Hello guys i just started learning C and decided to make a simple guess game, but im having some trouble. My code is always printing out the else condition why?Photo of my code
I have question regarding for loops and functions, so there list of values which as three input variables which are values for example 0-5 or direction (West, North etc), I am not sure if I using If statement correctly. Have I done something wrong with for loop command or the function?
Example of array input variables but there isn't any set limit in data set:
['Start', 'Bottom right', 1]['South', 1, 1], ['North', 3, 4], ['West', 4, 0], ['West', 2, 0], ['South', 3, 4]
If I run the function, it will always give me else function and won't follow any of commands.
def follow_path(a):
legend() #draw legend
for draw in a:
direction(a[0])
location(a[1])
choosetoken(a[2])
def location(corner):
if corner == 'Top left':
goto(0,600)
if corner == 'Top right':
goto(600,600)
if corner == 'Bottom left':
home()
if corner == 'Bottom right':
goto(600,0)
if corner == 'Center':
goto(300,300)
if corner == 1:
forward(100)
if corner == 2:
forward(200)
if corner == 3:
forward(300)
if corner == 4:
forward(400)
if corner == 5:
forward(500)
else:
print ("Check input '1' is correct or not")
def direction(direction):
if direction == 'West':
setheading(180)
if direction == 'East':
setheading(0)
if direction == 'North':
setheading(90)
if direction == 'West':
setheading(270)
if direction == 'Start':
home()
else:
print ("Check input '0' is correct or not")
def choosetoken(a): #Draw shapes
if a == 0:
youtube()
elif a == 1:
chrome()
elif a == 2:
googledrive()
elif a == 3:

elif a == 4:
photo()
else:
print ("Token Value out of range, check if input '2' is correct or not")
I am trying to write a function that returns the number of prime numbers that exist up to and including a given number.
Initially this was my code:
def count_primes(num):
prime = [2]
x = 3
if num < 2:
return 0
while x <= num:
for y in prime:
if x%y == 0:
print('not prime')
x+=2
break
else:
prime.append(x)
x += 2
return len(prime)
How ever I realise this code will run forever because of the following line of code:
for y in prime:
if x%y == 0:
print('not prime')
x+=2
break
else:
prime.append(x)
x += 2
Can anyone help to explain to me why will this end up with an infinite loop compared to the following code?
for y in prime:
if x%y == 0:
print('not prime')
x+=2
break
else:
prime.append(x)
x += 2
Last time I posted a quite vague story about a date difference challenge which I haven't solved yet. I will try to elaborate since I have tried everything in my power and the problem still isn't fixed.
I currently have three columns.
F)
G)
H)
*Th thing which makes this case difficult is that only weekdays are included.
So, for example:
If a car starts repairs on Monday 1st of August, the finish date is Tuesday the 14th of August.
I tried to solve this with the following formula:
=IF(WEEKDAY(F218)=2;(F218+11);
IF(WEEKDAY(F218)=3;F218+12;
IF(WEEKDAY(F218)=4;F218+13;
IF(WEEKDAY(F218)=5;F218+14;
IF(WEEKDAY(F218)=6;F218+15)))))
In other words:
If startdate = Monday then startdate + 11,
if startdate = Tuesday then startdate + 12, etc.
This works, but I have 300+ rows and dragging this function down doesn't change the cell references.
I know about the NETWORKDAYS and WEEKDAY functions, but I encounter problems with any Monday where only 1 weekend passes and other days where 2 weekends pass.
I'm not sure if this is possible, or how to achieve this. I thought maybe a nested IF statement?
I am checking the product count in Woocommerce to check for a maximum of 4 items from a given category. I would like the IF statement to have logic as follows:
Currently whats happening is that the alert is triggering successfully for when 3 items becomes 4 items in the cart. But then it triggers the javascript alert again when the user attempts to add another and added_to_cart event fires.
success: function (response) {
$.each( JSON.parse(response), function( category, count ) {
if( count == 4 ){ //IF STATEMENT HERE
swal({
type: 'success',
title: "You've Added The 4 Minimum "+category+" Items!",
allowOutsideClick: false,
showCancelButton: false,
showConfirmButton: false,
timer: 3000,
})
}
My script prints multiple copies of the $value in the hash because there is likely a problem with the way my if statement is written. It is printing the entire hash for each occurrence where there is a regex match.
How do I restructure my if statement such that for each match only the corresponding value is printed and not the entire array?
Example Input
1 ..... A
2 ..... A
3 ..... WT00
4 ..... WT00
Example Output
3
4
3
4
Desired Output
3
4
Script
#!/usr/bin/perl
use strict;
use autodie;
use File::Basename;
my $input_path = $ARGV[0];
my %hash;
my $key;
my $value;
open(my $input_fh, "<", $filename) or die $!;
while (my $data = < $input_fh > ) {
chomp $data;
my@ columns = split '\s+', $data;
my($firstletter) = ($columns[2] =~ m/^(\w)/);
my($coordinates) = sprintf("%9.5f%16.5f%16.5f\n", $columns[5], $columns[6], $columns[7]);
$key = $columns[10];
$value = $columns[1];
$hash {$key} = $value;
if ($key =~ m/WT00/){
print "$hash{$key}\n";
}
}

I need to know which is better switch or if-else, but in my case, it will be sensitive because I will add condition rules for APIs, so I need to know the best way to switch between APIs condition without damage memory,
Note: the page will load with the condition, I will not switch between them in SPA, no It will load by condition but I need to know which better to make sure other conditions contain APIs off If user don't choose it
there are many roles and this role knows as props, so user will update it manually and refresh the page, I need to make sure other condition will be off, and which is better as a performance

Help me guys!
I am having problem with multiple conditions in R. My data is like this:
Region in UK Year Third column (year.city) Liverpool 2008
Manchester 2010 Liverpool 2016 Chester 2015 Birmingham 2016 Blackpool 2012 Birmingham 2005 Chester 2009 Liverpool 2005 Hull 2011 Leeds 2013 Liverpool 2014 Bradford 2008 London 2010 Coventry 2009 Cardiff 2016 Liverpool 2007
What I want to create is a third column in a way that it has for groups in it: Liverpool before 2010, Liverpool after 2010, Other cities before 2010, other cities after 2010. I tried couple of codes like mutate but could not solve it. May you please help me to do it? Thanks
So I thought I found a typo in code I was working on. I thought 'not' would operate on string "eta" and make it False and False is not in the List,so nothing should print - however in both the below case "Eta not found" is printed. I guess this has something to do with order of evaluation that both statements are equal.
if not "eta" in ["alpha", "beta", "gamma"]:
print ("Eta not found")
if "eta" not in ["alpha", "beta", "gamma"]:
print ("Eta not found")
Im trying to aggrigate huge array of objects to single object, but my if statements replace each other:
const obj = [];
res.map((el) => {
if (el.resource.name === "FORM01" && el.name === "cost.ttl") {
obj[el.resource.name] = { [el.name]: el };
}
if ( el.resource.name === "FORM01" && el.name === "cost.use") {
obj[el.resource.name] = { [el.name]: el };
}
});
in result i wat add in obj[el.resource.name] = {} two fields "cost.ttl" and "cost.use".
I have written some PHP code, which shows an author alias if the variable is set, if not it shows the author.
I've written the following code, but it's not working.
The site is running PHP 5.3.10
<?php if (!empty($author_alias)) {
echo $author_alias
}
else {
echo $this->item->author;
} ?>
So I have been trying to find out a more beautiful way to actually do some fault and errors in a script I am working on.
Basically I have a json_resp = resp.json() who either gives me values or [] meaning either there is something or not.
Now the question I am having trouble with is that I don't know which way is the best to repeat a function if it is empty, shall I repeat the whole function or what else would be most "best reason" to solve it in a good way?
What I have done is that I changed the objects from the json resp to a len. If its 0 then repeat else do other stuff:
#json_resp['objects'] either has empty [] or not always.
json_resp = resp.json()
if len(json_resp['objects']) == 0:
print('Sleeping in 2 sec')
time.sleep(2)
run_method() #Shall I call the function to start over?
else:
print(len(json_resp['objects']))
continue do rest of the code
As you can see right now I am compare with len of the json_resp but what makes me unsure is that if it is a good way to actually call the function again? Wouldn't it have a limit or maybe delay the whole process... Im not sure but what is your thoughts of making this function "better, smarter, faster"?
My thought was maybe to either put a try except or while loop that? Let me know what you guys think
I am currently using a for loop and multiple if statements to count the number of records that match a string.
for (var i = 0; i < DailyLogs.length; i++) {
if (DailyLogs[i].created_at >= this.state.startMonth && DailyLogs[i].created_at <= this.state.finishMonth) {
if (DailyLogs[i].created_by_id === "37aa0778-c148-4c04-b239-18885d46a8b0" ) { md1++; }
if (DailyLogs[i].created_by_id === "869a7967-ffb3-4a20-b402-ad6d514472de" ) { md2++; }
if (DailyLogs[i].created_by_id === "92c0f155-ce82-4b50-821f-439428c517a3" ) { md3++; }
if (DailyLogs[i].created_by_id === "aa9eb0f2-35af-469a-8893-fc777b444bed" ) { md4++; }
if (DailyLogs[i].created_by_id === "967d63ea-492c-4475-8b08-911be2d0bf22" ) { md5++; }
if (DailyLogs[i].created_by_id === "47ec8d60-1fa2-4bf5-abc8-34df6bd53079" ) { md6++; }
if (DailyLogs[i].created_by_id === "92c0f155-ce82-4b50-821f-439428c517a3" ) { md7++; }
}
}
Is there a better way to do this, apart from having multiple if statements, or perhaps shorting this somehow.
I have a function for checking the type of a $value is valid or not. My current code is a simple switch case with too many cases exceeding the cyclomatic complexity to 17. I need to add more cases as well as reduce the complexity.
/**
* Check type of attribute value
* @param $type
* @param $value
* @return bool
*/
public function typeCheck($type, $value)
{
$this->value = $value;
switch ($type) {
case 'string':
return is_string($value) || is_integer($value) || is_bool($value);
case 'StringNotNull':
return is_string($value);
case 'LongStringNotNull':
return is_string($value);
case 'SuperLongStringNotNull':
return is_string($value);
case 'FortyStringNotNull':
return is_string($value) && (strlen($value) < 41);
case 'integer':
return is_numeric($value);
case 'positiveInteger':
return is_numeric($value) && ($value > 0);
case 'boolean':
return is_bool($value) || ($value == 'true' || $value = 'false');
case 'float':
return is_numeric($value);
case 'decimal':
return is_numeric($value);
case 'PositiveDimension':
return is_numeric($value) && ($value > 0);
case 'Dimension':
return is_numeric($value) && (strlen($value) < 13);
case 'Barcode':
$validator = $this->getBarcodeValidator();
$validator->setBarcode($value);
return is_string($value) && (strlen($value) < 17 && $validator->isValid());
case 'dateTime':
return true;
case 'normalizedString':
$this->value = strip_tags($value);
return is_string($value);
default:
return is_string($value);
}
}
Any better way around?
this is my first attempt at making a program. I want to time how long it takes for the user to type what is displayed on the screen, however, it is only timing once every two tries.
For example X might be displayed they type X and it doesn't time. When e.g. Y appears next and they type Y it will time it, and it just goes round in circles like that.
This is what i have so far sorry if it's bad.
answer.addKeyListener(new KeyAdapter() {
long entryStart;
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_ENTER)
{
countTime++;
if (countTime % 2 != 0) {
entryStart = System.currentTimeMillis();
}
if (countTime % 2 == 0)
{
long entryEnd = System.currentTimeMillis();
long differenceEntry = (entryEnd - entryStart);
timeField.setText(String.valueOf(differenceEntry / 1000.0));
}
if (answer.getText().isEmpty()){
JOptionPane.showMessageDialog(answer, "Error!");
}
if (answer.getText().equals(matchingField.getText())){
points++;
pointsField.setText(String.valueOf(points));
}
else {
incorrectpoints++;
incorrectField.setText(String.valueOf(incorrectpoints));
points--;
pointsField.setText(String.valueOf(points));
}
matchingField.setText("");
answerField.setText("");
StringGenerator sg = new StringGenerator();
matchingField.setText(sg.randomString());
}
}
Also if you could provide any details on how I could improve my code that would also be appreciated. Thank you.

UPDATE:
using:
listTransactions.getStatus().equals("PENDING")
seems to work. But why doesn't it work the other way? I admit I'm newish to Java coming from C# but this is as elementary as it gets. Does Java not use "==" with Strings?
Hello,
In the below snippet:
Log.d("test",listTransactions.getType()+" "+listTransactions.getStatus());
if(listTransactions.getType()==2 && listTransactions.getStatus()=="PENDING")
{
Log.d("test2","WORKING");
}
the Log.d output is
D/test: 2 PENDING
but for some reason the code inside IF does not evaluate.
getType() returns int and getStatus() returns String.
I've spent the last half hour trying to re-write it with the same result. What could be causing this?
Many thanks for your time.
I'm writing a bash script for inventory information, and i'm attempting to collect data on two seperate version of Red Hat. They have two different types of output for the ifconfig, so i'm simply trying to add an 'if' statement to the already working function. I keep getting an error that says syntax error: unexpected end of file . I assume i'm not closing something somewhere, but I can't seem to see it, though i've probably been looking at it too long. any assistance would be great.
Here is the script
#!/bin/sh
OS_VERSION=`cat /etc/redhat-release |awk '{print $0}'`
pat=".*Santiago.*"
num=1
if [[ "$OS_VERSION" =~ $pat ]]; then
for i in `/sbin/ifconfig -a |grep -i -B 3 "UP" |grep -i "HWaddr"|awk '{print $1}'`
do
{
MacAddress=`/sbin/ifconfig $i |grep -i -B 3 "UP" |grep -i "HWaddr"| awk '{print $NF}'`
Ip_Address=`/sbin/ifconfig $i|grep -i "inet addr"|awk '{print $2}'|awk -F: '{print $2}'`
echo -n "ethName$num=$i | ethMac$num=\"$MacAddress\" | ethIp$num=\"$Ip_Address\" | "
num=$(expr $num+1|bc)
}
else
echo "Not Santiago, use other script"
done;
echo "";

I'm working on a program that's based on a device used in the early 20th century. While testing on parts of the program, a part of the code doesn't work like I thought it would. Here is some code that is similar to it:
@echo off
setlocal enabledelayedexpansion
cls
set /p ar=Type a number:
:loop
for /l %%a in (1,1,100) do (
set var1=%%a
if !var1! equ %ar%(
echo It worked
goto pause1
) else (
echo It didn't work
)
)
:pause1
pause
What I'm trying to do here is comparing the "%%a" variable with a variable set outside of the FOR command, but every time I tested the program, it would suddenly exit from the command prompt. I have tried changing the order of the commands, and changing the symbols, but the output is the same. I've checked many references and I haven't found any that tackles this certain scenario. Can you tell me what I'm doing wrong here and what to do to fix it? Thank you.

The last 2 lines is where I am showing an issue in PyCharm. It says "Statement has no effect" but when I remove the 0 the code does not operate correctly - so clearly the 0 does have an effect. Is there something else I should have in the place of a 0 so that it does not throw this code? Or is it just a false-positive in PyCharm?

Situation:
Cell A1 is a number (age of a person)
Cell B1 generates one of 2 texts.
I can't get to the solution of this: If A1 is larger then 14 and smaler or equal to 17 it should give text A. If A1 is larger then then 17 it should give text B. But if A1 is empty B1 should stay empty too.

I have a form that if a field is blank, it tells the user that it can't be blank, and gives the user the option to fill in the blank field (Yes) or close the form (No). Problem is that when the user picks No (or close the form), it gives me a run-time error 2585. After researching, I have it checking if the field is blank on the field after using On Got Focus. (After Update on the field didn't work because there's no update if it's blank.) Here's my code:

For my thesis work I was suggested to use a related code made in year 2000 on Matlab; when transcribing it I found the next syntax for some if loops:
if \ min(x)>= 0
statement;
end
However it is not valid anymore for recent software's versions. I did some search on Google but using "\" is pretty ambiguous and found nothing out of conditionals. Do you know what does it stand for?
Desired Behaviour:
I want to change the value of a cell if and only if a cell current value of another cell matches some constant string value (only alpha characters) I have chosen.
Code:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
With ActiveWindow
Dim sht As Worksheet
Set sht = ThisWorkbook.Sheets("Sheet1")
Dim selection As Long
selection = Target.Cells.CountLarge
Dim someString As String
someString= "something"
If selection = 1 Then
If (Target.Column = 4 And Target.Value = someString And IsEmpty(Target) =False) Then
thisrow = Target.Row
sht.Cells(thisrow, 5).Value = "N/A"
End If
End If
End With
End Sub
Question: Is there a better way to handle this? The first if statement is necessary to ensure one cell is selected and to avoid error message type mismatch.
I have data that is in the structure of: Subject > Category > Subcategories
e.g.
Planet of the Apes
-Scifi
--Movie
--TV series
-Popular
--Remake
--Cult Classic
----------------
BBC News
-Topical
--Daily News
-Geographical
--UK
--England
(the data isn't actually as bad this!)
I'm trying to work out the best way to convert this into something I can work with to filter and sort. Since the data currently is plain text, I've got an if statement that works out if it's a Subject, Category, or Subcategory but what would be the most sensible way to build a hashtable out of data like this?
$processedData = @{}
$versionattribs | ForEach-Object{
if($_ -match "^\s*$" -or $_ -match "Inherits.*")
{
# Is a blank line
}
elseif($_ -notmatch "`t")
{
# Is a Subject
Write-Host "Subject: $_ "
$Subject = $_
}
elseif($_ -match "`t" -and $_ -notmatch "`t`t")
{
# Is a category
Write-host "Category: $_"
$category = $_
}
elseif($_ -match "`t`t")
{
# Is a sub-category label
Write-Host "Label: $_ "
$label = $_
}
else
{
#Unexpected attribute
Write-host "Error - unexpected line indentation : $_"
}
}

Once I get that error, I cannot use the ELSE statement in that window; I must start a new shell process, at which point my scripts work as expected. For example, once that error occurs in a window, I observe the following:
C:\> IF DEFINED AN_ENV_VAR (ECHO YES) ELSE ECHO NO
ELSE was unexpected at this time.
C:\> IF NOT DEFINED AN_ENV_VAR (ECHO YES) ELSE ECHO NO
ELSE was unexpected at this time.
C:\> IF DEFINED AN_ENV_VAR (ECHO YES)
C:\> IF NOT DEFINED AN_ENV_VAR (ECHO YES)
YES
A new shell gives expected results:
C:\> IF DEFINED AN_ENV_VAR (ECHO YES) ELSE ECHO NO
NO
C:\> IF NOT DEFINED AN_ENV_VAR (ECHO YES) ELSE ECHO NO
YES
C:\> IF DEFINED AN_ENV_VAR (ECHO YES)
C:\> IF NOT DEFINED AN_ENV_VAR (ECHO YES)
YES
Is there any way to fix the current shell?
I have two numpy arrays similar to these, which represent coordinates:
import numpy as np
x=np.array([1,3,2,4,6,5,4,1])
y=np.array([4,4,3,2,2,1,3,5])
I also have n squares:
s1 -> x=0 to 3, y=0 to 3
s2 -> x=3 to 6, y=3 to 6
s3 -> ...
s4 -> ...
and I want to count the number of points falling within each square. This comes down to evaluating n inequalities.
My approach is verbose and (probably) inefficient:
count1=0
count2=0
count3=0
count4=0
for j in range(0, len(x)):
#Square 1
if x[j]<=3 and y[j]<=3:
count1+=1
#Square 2
if x[j]<=3 and y[j]>3 and y[j]<=6:
count2+=1
#Square 3
if x[j]>3 and x[j]<=6 and y[j]<=3:
count3+=1
#Square 4
if x[j]>3 and x[j]<=6 and y[j]>3 and y[j]<=6:
count4+=1
Given my two arrays, this returns:
In[1]: count1, count2, count3, count4
Out[1]: (1, 3, 4, 0)
My real problems consists of a variable number of squares (it could be 6, it could be 36, etc.).
Is there a way I can automate both the generation of the count variables, as well as the number and boundaries of the if statements?
n=range(101)
if n%2==0:
print("weird")
if range(2,6):
print("not weird")
if range(6,21):
print("weird")
if n>20:
print("not weird")
else :
print("weird")
Given an integer, , perform the following conditional actions:
If is odd, print Weird If is even and in the inclusive range of 2 to 5, print Not Weird If is even and in the inclusive range of 6 to 20 , print Weird If is even and greater than 20, print Not Weird
This is a self-answered question.

What is the best practice for conditionally enforcing states (depending on other command outputs)?
Here's my case:
# vim: set syntax=yaml:
# Ensures that outbound connections are allowed for httpd
httpd:selinux:
cmd.run:
- name: /usr/sbin/setsebool -P httpd_can_network_connect 1
Now, I only want to run this if SELinux is enabled (enforced).
Today I've come across an interesting bit of C# code:
if(!myobject) { /*Do Stuff*/ }
It does seem to behave the same as:
if(myobject == null) { /*Do Stuff*/ }
... but is it really the same thing? I haven't found any documentation about this anywhere yet.
Is there a reason to not use the shorter version or prefer one over the other?
#include<stdio.h>
int main()
{int y=1;
if(y&(y=2))
printf("true %d\n",y);
else
printf("false %d\n",y);
return 0;
}
how does the ouput come as true 2? according to me inside the if condition this will happen "if(1&(2))" but the output comes as true 2 .
I want to create a column in mysql workbench where there is a sum of the duration of a behaviour when multiple columns (e.g condition, trial, subject, behaviour type...) are the same.
I am relatively new to working in sql and have so far mostly just used it for extracting data. Is this something that is possible? If so how do I go about it?
Thanks :)
First time I post here ! Hope my question will be relevant.
I defined a function to exclude a category in a calendar which works well when I execute it like this:
function tribe_exclude_events_category_month_list( $query ) {
if ( isset( $query->query_vars['eventDisplay'] ) && ! is_singular( 'tribe_events' ) ) {
if ( $query->query_vars['eventDisplay'] == 'list' && ! is_tax( Tribe__Events__Main::TAXONOMY ) || $query->query_vars['eventDisplay'] == 'month' && $query->query_vars['post_type'] == Tribe__Events__Main::POSTTYPE && ! is_tax( Tribe__Events__Main::TAXONOMY ) && empty( $query->query_vars['suppress_filters'] ) ) {
$query->set( 'tax_query', array(
array(
'taxonomy' => Tribe__Events__Main::TAXONOMY,
'field' => 'slug',
'terms' => array( 'reunions'),
'operator' => 'NOT IN'
)
) );
}
}
return $query;} add_action( 'pre_get_posts', 'tribe_exclude_events_category_month_list' );
But what I want is to execute it if only if user is logged in. So I did this :
function tribe_exclude_events_category_month_list( $query ) {
if ( isset( $query->query_vars['eventDisplay'] ) && ! is_singular( 'tribe_events' ) ) {
if ( $query->query_vars['eventDisplay'] == 'list' && ! is_tax( Tribe__Events__Main::TAXONOMY ) || $query->query_vars['eventDisplay'] == 'month' && $query->query_vars['post_type'] == Tribe__Events__Main::POSTTYPE && ! is_tax( Tribe__Events__Main::TAXONOMY ) && empty( $query->query_vars['suppress_filters'] ) ) {
$query->set( 'tax_query', array(
array(
'taxonomy' => Tribe__Events__Main::TAXONOMY,
'field' => 'slug',
'terms' => array( 'reunions'),
'operator' => 'NOT IN'
)
) );
}
}
return $query; }
function exclude_category_when_logged_in() {
if ( is_user_logged_in() ) {
add_action( 'pre_get_posts', 'tribe_exclude_events_category_month_list' );
}} add_action( 'init', 'exclude_category_when_logged_in' );
But this doesn't seem to work.
Could you help please ? Thanks a lot Lucas
I have code that compares userinput from EditText to the correct translation(String[] answers). Now i wrote a if/else statement but I'm trying to put that in a for loop. Otherwise I need to write over 30 statements. just with a few numbers different.
Now I have came up with the following 'basis':
for(int i = 0; i < answers.length; i++){ if (Uinput[].equals(answers[])) { edit1.setBackgroundColor(Color.parseColor("#00FF00")); } else { edit1.setBackgroundColor(Color.parseColor("#FF0000")); } }
What do I need to put between the brackets([]) as it wont allow it empty, and further any recommendations or changes? Thanks in advance.
Code sample of what I'm currently using:
private String[] answers = {"daylight", "task"};
private EditText edit1;
this.edit1 = findViewById(R.id.edit1);
String Uinput[] = {edit1.getText().toString()};
// Comparison 1
if (Uinput[0].equals(answers[0])) {
edit1.setBackgroundColor(Color.parseColor("#00FF00"));
}
else {
edit1.setBackgroundColor(Color.parseColor("#FF0000"));
}

I need to break out both the while loop and if statement when the the value inside the if statement is great than 0, in turn the code should then break from the while loop.
How can I achieve this?
My code is as follows:
it('x Accordion description should appear after 5 seconds upon being clicked', function(done) {
//this.timeout(15000);
//setTimeout(done, 6000);
var i = 0;
while (i < 15000) {
browser.click('#accordion');
//var timeoutText = browser.getText('#timeout').length;
var timeoutText = browser.getText('#timeout').length;
console.log(timeoutText);
if (timeoutText > 0) {
browser.pause(5000);
console.log("Pass");
break;
i++;
}
}
Thanks for your help.
The purpose of this code is trying to output the route where the second element of one tuple is the same as the first element of another tuple.
When the i += 1 has the same indentation as for loop, "JFK" is the origin, path = segments. I got ['JFK', 'DEN', 'SFO', 'LAS', 'LAX', 'ORD', 'ATL'] which is the correct answer.
When i += 1 has the same indentation as if statement, I only got ['JFK', 'DEN', 'SFO', 'LAS']. Does anyone know why???
segments = [("JFK", "DEN"), ("LAX", "ORD"), ("DEN", "SFO"),
("LAS", "LAX"), ("ORD", "ATL"), ("ATL", "JFK"), ("SFO", "LAS")]
def get_route(path, origin):
my_list = []
i = 0
list_len = len(path)
path_copy = path.copy()
while i <= list_len:
for k in path_copy:
if origin == k[0] and origin not in my_list:
my_list.append(k[0])
origin = k[1]
path_copy.remove(k)
i += 1
return my_list

I'm fairly new to arrays and I was interested in using it to control a series of thumbnail positions whenever a next or previous arrow is pressed. Additionally these thumbs should loop whenever an image completes a cycle across the array. I used a series of if/else statements and splice to add and remove thumbs that needed to be recycled.
I was successful at getting the Next button to accomplish the task I was working to achieve, but I cannot seem to get the Previous button to behave the same way and reverse the thumbnail flow in the opposite direction. I've tried many different things, but have had no success.

am completely new to programming and I am learning through edX now and I came across this code but I do not really know why the code is termed incorrect even though it gives an output. would have asked on the edx platform but the course finished two years ago, just learning from what is archived. Thanks .
The result is 'i win' and 'tie' it has an output so why is it still incorrect?
comp = 'rock'
user = 'rock'
if comp == 'rock':
print 'I win *_*!'
if user == 'paper':
print 'You win.'
else:
print 'Tie.'

Hi there I have become stuck with an exercise on if-else statements in java the problem is when I run the code it prints; Enter a card: 9 S end 9ofS
please see below for my code example:
String suit;
String rank;
String userOne;
Scanner sc = new Scanner( System.in );
System.out.print("Enter a card: ");
rank= sc.next();
suit= sc.next();
userOne= sc.next();
if (userOne.equals("9")){ System.out.println("Nine");
} else if (userOne.equals("S")){ System.out.println("Spades");
} System.out.print(rank+ "of" +suit);
had to squeeze the code in at the bottom I know its not in the right format but for just getting an answer to this question I had to lay it out like that.
Why is the code printing out- Enter a card: 9 S end 9ofS instead of Enter a card: 9 S Nine of Spades ?
I have a project that requires Java-Mysql connectivity. Here I require the use of if-else blocks within the try and catch statements.

This question already has an answer here:
this is my first post on SO, so forgive me if the formatting is wanting.
I'm trying to write a utility script that checks whether required packages are installed and installs the packages if not installed. I am trying to use a for loop to do this. For example,
requiredpackages <- c("FinancialMath", "FinCal", "ggplot2")
for (pkg in requiredpackages) {
if (pkg %in% rownames(installed.packages()) == FALSE)
{install.packages(pkg)}
if (pkg %in% rownames(.packages()) == FALSE)
{library(pkg)}
}
When I run this script, however, I get the following error message: "Error in library(pkg) : there is no package called ‘pkg’"
What am I doing wrong?
Thank you for your time.
I have a form in which the user inputs a number, and I want my macro to check whether the number exists in a specific list in order to do some stuff. Here's how I did it:
Private Sub CommandButton3_Click()
Dim number As Integer, i As Integer
For i = 10 To 10020
If TextBox1.Value = Sheet1.Cells(i, 2).Value Then
number = TextBox1.Value
End If
Next i
MsgBox "A dica número " & TextBox1.Value & " não consta na lista.", vbOKOnly, "Dica não encontrada!"
Exit Sub
'Do the rest of the code here
End Sub
The thing is: no matter what number I input, the message box always comes up. number = TextBox1.Value is never read. I've tried manually checking if the values were the same for a specific input with message boxes, and even though they were the same, If/Else was never accessed.
Any help would be appreciated.
How I can check if parameter it contains variable or string for example :
String text = "hello";
//I want like this
Demo(text);
//But if he wrote like this give him error
Demo("hello");
public void Demo(String text) {
}
int pi_digits1=0;
int pi_digits2=0;
System.out.println("Would you like from starting to fixed no. or for a
range:\n1.Fixed no\n2.Range");
byte choice = input.nextByte();
if(choice ==1){
System.out.println("Enter the no. of digits after decimal within 1 million
of pi to see and play");
pi_digits2=input.nextInt();
}
else if(choice ==2){
System.out.println("Enter the smaller +ve no of range");
pi_digits1=input.nextInt();
System.out.println("Enter the larger +ve no of range");
pi_digits2=input.nextInt();
System.out.println("Check");
}
else{
System.out.println("Wrong choice.Program terminated");
}
When the choice is 1,loop works fine. But for the choice 2,after taking inputs for pi_digits2 ,it is still asking for inputs.
Check is also being printed,but program is strucked in input loop and hence further code is not being executed.
Program executed in Bluej environment

This question already has an answer here:
I am trying to see if my UITextField.text matches any of the strings in my array exactly. As I am using letters I need to know if the text matches exactly and not just contains elements from the array.
In the if statement I am not sure what to put after 'cameraBodies' to search over the whole array?
Thank you for any help
let cameraBodies = ["A","B","C","D","E","F","G","H","I","J","K",
"L","M","N","O","P","Q","R","S","T","U","V",
"W","X","Y","Z","Other"]
if cameraBodyTextField.text != cameraBodies (Here is the problem) {
print("Does not match")
} else {
print("Does match")

I am trying to figure out how can i distribute particular elements of a list, based on an if statement.
This is the list:
@x = ["american", "assistive", "audio", "blind", "braille", "closed-captioning", "closed-captioning", "deaf", "low", "phone", "question-circle", "question-circle", "sign", "tty", "universal", "wheelchair"]
This is my haml code:
%ul.list-inline
- @x.each do |i|
- if i[0].length < i[1].length
%li
%i{:class=>"fas fa-#{i[0]} fa-2x"}
%span.f6 #{i[0]}
- else
%li
%i{:class=>"far fa-#{i[1]} fa-2x"}
%span.f6 #{i[1]}
What i am trying to do, is to determine the length of each string in the list and compare it to the length of the next string in the list.
Once the second string is determined as being a duplicate, it should go under the else statement.
The problem i am facing, is that by going with i[0], instead of the first string in the list, i am getting the first letter of the each string in the list.
I don't know if my way of using length is the best way to solve this issue, so if anyone else has a better solution i am open for it, as long as it gets the job done.
I am thinking that maybe if i could filter the elements in the list based on which elements are unique and which are duplicates, i could then distribute them accordingly.
But how i do that?
Thank you.
I have designed UML diagrams in different tools such as plantUML. I am looking for a way to add condition to execute a part of the code. Is it possible ? For example, I will present only the first part if the input value is 1 and the second part if the value is 2, etc... Any idea please?

df <- as.data.frame(LETTERS[seq( from = 1, to = 10 )])
names(df)<- c("Letters")
I want to apply the function on the dataframe:
df$result <- new_function(df$Letters)
And it doesent work (the function only writes "Correct")
i get this warning:
Warning message: In if (x %in% letters) { : the condition has length 1 and only the first element will be used

I am trying to update my database and im getting "Parse error: syntax error, unexpected 'if' (T_IF)" on my second if statement and i cant seem to find the error. Please do help me. Thank you.
Here's my code:
<?php

if (isset($_POST['update'])) {
$name = $_POST['stockname'];
$code = $_POST['stockcode'];
$des= $_POST['stockdes'];
$sql = mysqli_query($conn, "UPDATE SIInfo SET StockName = '$name', ProductCode='$code', StockDescription = '$des' ")
**if ($sql)** {
echo "<script>alert ('Record Updated!')</script>;";
include ('../SI/selectSI.php');
}else{
echo "<script>alert ('Error! Failed to update.')</script>;";

This question already has an answer here:
Can i use multiple if and then after an else like this ?
if(sky == 'blue') { ... }
if(sky == 'red') { ... }
else { alert('Sky is not blue or red'); }
When do I need else if ?
Thanks.
I’m writing a program in the Java language, and I’m using if else statement. In this program i need to input word(s), i.e., alphabet character that has been assigned to be the values of the String data type. So that the program will print the sequential if statement, but is seems that program is not recognizing the input, because it keep printing only else statement. I need to know how to assign String values in Java language, import java.util.Scanner; on an if else Statement algorithm.
import java.util.Scanner;
public class Compare
{
public static void main (String []args)
{
Scanner input = new Scanner(System.in);
String name = “Henry”;
System.out.println(“Enter a NAME”);
name = input.nextLine();
If ( name = “Henry”)
System.out.println(“Welcome Henry”);
else
System.out.println(“Invalid Input”);
}
}
When i run it in CMD:
C:\CODE>java Compare
Enter a NAME:
Henry
Invalid Input
It doesn’t accept the String value “Henry” thats why the else statement keeps displaying “Invalid Input”.
I have 2 columns in Sheet 1 (named Projects), "Projects" in column A and "Status" in column B. The number of rows is dynamic.
In Sheet 2, I want to extract the projects that meet a certain string criteria and populate a table. For example, if the Status is "Operating", take the project name in column A for that row and put it in a table.
I tried =IF(Projects!B1:B="Operating",Projects!A1:A,"") but it returns the names of the projects in the same row position as in Sheet 1. So if there is a 2 row gap in Sheet 1 between two operating projects, it keeps the 2 row gap in Sheet 2.
How do I get rid of the gaps?
My question is, what's the best way to verify two conditions?
In this case the conditions are not very long but what's the best pratice? Should I create 2 if's or should I use the AND (&&) operator?
Example:
if ( A > X AND A > Y)
code here...
ENDIF
Ou:
if ( A > X )
if ( A > Y)
code here...
ENDIF
ENDIF
I'm new to Java (and programming in general), so apologies if some of this doesn't make sense and/or if the code is really bad:
I am trying get a unique four digit code from a user input (that is what the Keyboard.readInput line does), and I have put in a couple of conditional statements to ensure that the code that is entered can only be 4 digits and that each digit must be different to the other three.
The if statements work as intended in the sense that they output the error message and prompt them to re-enter (i.e. the method getPlayerGuess() gets called). For example, if the user enters 123 (i.e. userGuess.length() != 4), it will prompt them to enter again. If they then enter 1234, the method will complete.
However, the problem I have is that when I call this method in another class that I have, the code that is being pulled through is the first code entered (i.e. 123) and not the four digit one I want (i.e. 1234) - which is resulting in an arrayOutOfBoundsException.
Any ideas on how I can ensure that the code that is being returned is the four digit one that passes the conditionals, and not the first one entered?
public int[] getPlayerGuess() {
System.out.print("Guess a four digit code: ");
String userGuess = Keyboard.readInput();
if (userGuess.length() != 4) {
System.out.print("Your code must be 4 digits - ");
getPlayerGuess();
}
int[] userCode = createArrayFromGuess(userGuess);
for (int i = 0; i < userCode.length-1; i++){
for (int j = i+1; j < userCode.length; j++){
if (userCode[i] == userCode[j]) {
System.out.print("Code must have four unique digits - ");
getPlayerGuess();
}
}
}
return userCode;
}
Just had to decompile my old code and i'm used to write it this way:
if(!x)
{
DoSth();
}
but the decompiler always wrote it this way if there is no code after the snippet:
if(x)
{
return;
}
DoSth();
Is there any performance advantage in calling return like in the lower code snippet or is it just a personal preference thing?
I am in a programming class to learn C++. We had to work on a if and else statement problem. Below is my code, and I am trying to figure out why it is halving it.
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int age;
double price;
char category;
double finalPrice;
cin >> price;
cin >> age;
cin >> category;
if (age <= 0) {
cout << "Wrong input";
}
if (age > 0 && age <= 5) {
if (category != 'A' || 'a') {
finalPrice = price - (( price * 100)/100);
cout << fixed;
cout << setprecision(2) << finalPrice;
}
else if(category == 'A' || 'a') {
finalPrice = price - (( price * 0)/100);
cout << fixed;
cout << setprecision(2) << finalPrice;
}
}

finalPrice = price - (( price * 50)/100);
cout << fixed;
cout << setprecision(2) << finalPrice;
}
else if(category == 'B' || 'b') {
finalPrice = price - (( price * 0)/100);
cout << fixed;

}
else if(category == 'D' || 'd') {
finalPrice = price - (( price * 0)/100);

}
if (age > 60) {
if (category != 'E' || 'e') {
finalPrice = price - (( price * 80)/100);

So above is my code for a assignment for school.
When I enter the values 14.56 25 C I get an output of 5.8.2
However my expected output should just be 14.56
Am I just overseeing something? I don't get how it is even getting half.
Thanks!
I have a working code that can insert and update information from the database and echoing it to page. but I like to hide the specific empty column while displaying all the information from the row. check this screenshot my goal is to hide the "image" column when its null/empty; so the crock image wont display. here is my code below:
<?php
$result = mysqli_query($mysqli, "SELECT * FROM blogs ORDER BY id DESC");
while ($row = mysqli_fetch_array($result))
if (!empty($row['image'] != ""))
{
echo "<div class='row'>
<div class='col-lg-12 box'>
<div class='content-heading'>
<p>
<text>".$row['title']."</text>
</p>
</div>
<p>
<text1 class='pull-right' >".$row['image_text']."</text1><br/>
<img class='img-size' id='hp'src='admin/upload_images/".$row['image']."'/>
<text>".$row['definition']."</text>
</p>
</div>
</div>";
}
?>
but this code if (!empty($row['image'] != "")) is hiding all the row from my database. can anyone have the right code from my problem?
This is my first question on SO, so my apologies if it is poorly composed.
The project I am working on involves a class, let it be myClass, which is similar to a set, and I need to allow the programmer to compare objects of this type in a meaningful way.
What I would like to be able to do is something like this:
myClass a, b;
...
if (a == b)
{
//execute code where a and b are implicitly used as
// each of a and b's elements, respectively
}
and have my custom if statement execute the conditional code for each pair of elements from a and b, based on the condition performed on the pair of elements.
Here is a more concrete example:
myClass a = {1, 2}, b = {2, 3};
if (a == b)
std::cout << a << " equals " << b << std::endl;
else
std::cout << a << " does not equal " << b << std::endl;
Where the result would be (not necessarily in this order):
1 does not equal 2
2 equals 2
1 does not equal 3
2 does not equal 3
Currently, I have comparison operators overloaded to return a "comparison type" which simply stores the two operands and the comparison function for lazy evaluation. Is there a way to accomplish this custom if/else behavior so that it occurs whenever an if statement receives a parameter of type "comparison type?" Or is it necessary to just define a regular function which accepts an object of this type and a reference to a binary operator function as the conditional code?
I saw this question, but simply defining a conversion to bool will not work in this case. C++ 'overloading' the if() statement
This question already has an answer here:
I know it's not the best way to write code, but I would like to fix what I have- not necessarily change the entire thing. I know there are parts where the code will stop since I haven't created anything else for it. At this point what I would like to fix is that once I call the initial_username function, and I enter N as the input for the confirm variable, it still prints what is under the if statement rather than calling the function within the elif statement.
def wrong_data():
print("I'm sorry, I didn't get that.")
fix_name()
def fix_name():
print("Let's try that again.")
fn_error= input('Please re-enter your first name: ')
ln_error= input('Please re-enter your last name: ')
second_confirm= input('Is your full name ' + str(fn_error) + ' ' + str(ln_error) + '? Please enter Y or N: ')
if second_confirm== 'Y' or 'y':
print('Thank you, ' + str(fn_error) + ' ' + str(ln_error) + '.')
def initial_username():
user_fn= input('Please enter your first name: ')
user_ln= input('Please enter your last name: ')
confirm= input('Is your full name ' + str(user_fn) + ' ' + str(user_ln) + '? Please enter Y or N: ')
if confirm == 'Y'or 'y':
print('Thank you, ' + str(user_fn) + ' ' + str(user_ln) + '.')
elif confirm == 'N' or 'n':
fix_name()
else:

I'd like to check if my vector / array is made of numbers.

I'm working in C# using Visual Studio and have been going over my code trying to improve its readability. I came across this site, that lists 15 best practices. #7 - Avoid Deep Nesting, it talks about If statements and says instead of using Else, make another If statement.
This got me wondering about the difference in the instructions between the two. Would using additional If statements cost more performance than just using Else?
Example:
if(condition)
{
actions;
}
else
{
actions;
}
OR
if(condition)
{
actions;
}
if(condtion)
{
actions
}
Any advice would be appreciated
I am running an if-statement to check if a file upload input is not empty. I am checking the fileNameVal with the following code if (fileNameVal != null) {. It seems to be always running true when it should not if a file input does not have anything within it.
The fileShow.text() code line is always displaying.
If you need to see this live, visit here.
Does anyone see what I am doing wrong?
var fileShow = $('#fileUploadMessage');
fileShow.hide();
var fileNameVal = '';
$('#uploadedFileTest').change(function () {
fileNameVal = $('#uploadedFileTest').val();
console.log(fileNameVal);
});
$("form#submit").submit(function (e) {
$.LoadingOverlay("show");

The function checks if array elements are same, if they are same it should return true.
When I use the function below, it gives the correct result.
var arr = [1, 2, 3, 4];
function isUniform(arr) {
var store = arr[0];
for (var i = 0; i < arr.length; i++) {
if (arr[i] !== store) {
return false;
}
}
return true;
}
console.log(isUniform(arr));
But when I use the function like this i.e; changing the if condition, it returns false
var arr = [1, 2, 3, 4];
function isUniform(arr) {
var store = arr[0];
for (var i = 0; i < arr.length; i++) {
if (arr[i] === store) {
return true;
}
}
return false;
}
console.log(isUniform(arr));

I'm working on a small VMware ESXi project (personal project, not for any company). Im trying to build a html file that contains a table with some information from ESXi OS, like time/date, OS version, patch number, etc. However there are some commands that give no output and then my table has an empty box (cell). What i am trying to do..and terribly failing at ...is that i am trying to put a simple if-else-fi statement in the shell script that would check if the output is empty or not. Here is the command i use the check if there is an output to the command or not:
if [ $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}') != " " ]; then echo "Not Empty!"; else echo "Empty!"; fi
The problem with this is, that while it gives the correct result, it also prints out the following:
sh: : unknown operand
Empty!
Yes, the result is supposed to be "Empty!", but i cant get rid of the "sh: : unknown operand" message. It seems it does not like that the != operand is not close to ")".
If however i put the "!=" operand close to the ")", like this:
if [ $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}')!=" " ]; then echo "Not Empty!"; else echo "Empty!"; fi
..it no longer gives the "sh: : unknown operand" message but it gives the wrong result "Not Empty!". If however i insert a command in the if-else-fi statement that gives an output, for example:
if [ $(esxcli system time get) != " " ]; then echo "Not Empty!"; else echo "Empty!"; fi
..it give no "sh: : unknown operand" messages and gives the correct result as "Not Empty!"
I have tried in the following ways but it gave the same "sh: : unknown operand" message:
if [[ $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}') != " " ]]; then echo "Not Empty!"; else echo "Empty!"; fi
if [ -n $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}') ]; then echo "Not Empty!"; else echo "Empty!"; fi
if [ -z $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}') ]; then echo "Not Empty!"; else echo "Empty!"; fi
if "$(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}')" == " " ; then echo "Not Empty!"; else echo "Empty!"; fi
if $(esxcli hardware ipmi bmc get |grep -i gate |awk '{print $2}')==" "; then echo "Not Empty!"; else echo "Empty!"; fi
How can i get rid of that message...What else can i do?

I am trying to make it so that when one cell (B1) reaches a value of 0, A1 which is text entered by user, is now replaced with the data in C1 which is also data entered by the user. Meaning that formulas cannot be placed in either A1 or C1 as they are data inputted by user (B1 already has formula calculating its value.)
Instinctly I want to use =IF(B1=0,A1=C1,"") but obviously that doesn't work as A1 = C1 is checking if they equal each other, not replacing A1 with C1.
There's probably going to be a simple solution to this but I cannot figure out a way to make it work.
I have a java-8 class:
class MyClass{
double field1;
double field2;
int field3;
...
float fieldN;
boolean isEmpty() {
// I want to implement this such that if all my numeric fields are 0's then return true else false
}
}
What would be the most elegant way of implementing isEmpty() instead of adding many different if(fieldX == 0 ) conditions in there ?
I have a function like below.
First, I change all class to "badge badge-secondary". Then, check text in span. If it is "right" and clicked, then change to "badge badge-primary". Else, it is "wrong" and clicked, changing to "class", "badge badge-danger".
Can I make my code more concise and righter?
function updateOrderType(ansType) {
lastAnsType = ansType;
var ansBadge = d3.select("#anstype").selectAll("span.badge");
ansBadge.attr("class", "badge badge-secondary");
ansBadge.filter(function() {
if (d3.select(this).text() == ansType) {
return d3.select(this).text() == "right";
}
}).attr("class", "badge badge-primary");
ansBadge.filter(function() {
if (d3.select(this).text() == ansType) {
return d3.select(this).text() == "wrong";
}
}).attr("class", "badge badge-danger");

I'm trying to run an if statement, where I want to run something IF any of 23 values is below a certain value.
test.df<-as.data.frame(c(1:50))
if (test.df[,c(27:50)] <30){ print("hi")}
I get the error that the condition has length > 1 and only the first element will be used. Which is true... Does anyone know how I can test this if statement for 23 values, whithout having to type them one by one?
Thanks!
Sorry, I'm kind of new to this.
Is there a specific reason, why the if-statement in this snippet is not working? If yes, could somebody point me in the right direction?
var app = (function(){
selector = {
app: ".js-app",
app__home: ".js-app__home"
}
foo();
foo = function () {
console.log(selector.app__home);
if ($(selector.app).hasClass(selector.app__home)) {
console.log("is home page")
}
}
})();
$(document).on("ready", function() {
app();
});
The first console.log()-output (the one outside the if-statement) works correctly though. Thanks!
I've found a bug in my code
func receive() (err error) {
if v, err := produce(); err == nil {
fmt.Println("value: ", v)
}
return
}
Error is never returning from this function, but I was absolutely sure it should.
After some testing I understood that err is redeclared in the if statement. More than that - all variables are always redeclared in short variable assignment inside if statement, despite they were declared before.
This is working code
func receive() (err error) {
v, err := produce()
if err == nil {
fmt.Println("value: ", v)
}
return
}
Here is an example: https://play.golang.org/p/1AWBsPbLiI1
Seems like if statement
//some code
if <init_statement>; <expression> {}
//more code
is equivalent to
//some code
{
<init_statement>
if expression {}
}
//more code
So, my questions:
1) why existing variables are not used
2) why such scoping is not mentioned in documentation/language spec
3) why compiler doesn't say that no one returns a value
I have a plot on which I want to plot either diagram A, or diagram B, or both.
Currently my structure is:

plot A
Is there a more concise / more elegant way?
So I'm trying to set up some dynamic text for a report in SSRS with 4 user parameter fields and I keep running into the same error. I'm still pretty new to SSRS and Visual Basic, so it's a bit hard to understand the error message.
System.Web.Services.Protocols.SoapException: The Value expression for the textrun
‘Textbox2.Paragraphs[2].TextRuns[1]’ contains an error: [BC33104] 'If' operator
requires either two or three operands.
The 4 parameter fields are beginYear, beginMonth, endYear, & endMonth. The following is the code I have in the expression:
If (bYear = eYear) And (bMonth = 1) And (eMonth = 3)
"3rd Quarter January - March " & eYear
ElseIf (bYear = eYear) And (bMonth = 4) And (eMonth = 6)
"4th Quarter April - June " & eYear
ElseIf (bYear = eYear) And (bMonth = 7) And (eMonth = 9)
"1st Quarter July - September " & eYear
ElseIf (bYear = eYear) And (bMonth = 10) And (eMonth = 12)
"2nd Quarter October - December " & eYear
ElseIf (bYear = eYear) And (bMonth = 1) And (eMonth = 12)
"Calendar Year " & eYear
ElseIf (bYear = eYear) And (bMonth = eMonth)
eYear & " " & eMonth
ElseIf (((Convert.toInt32(bYear)) = (Convert.toInt32(eYear)) - 1) And (((Convert.toInt32(eYear)) = (Convert.toInt32(bYear)) + 1) And (bMonth = 7) And (eMonth = 6)
"Fiscal Year " & bYear & "-" & eYear
Else
bMonth & " " & bYear & "-" & eMonth & " " & eYear
End If
So if I selected the following parameters from the report as follows (in the month parameters, I assigned numerical values to months):
-Begin Year=2018
-Begin Month=April
-End Year=2018
-End Month=June
I should see the following expression in the text box of the report => "4th Quarter April - June 2018"
So I have this data frame of a condition column and a value column. Suppose I want to change one of the values for which the condition is satisfied, but not all of the values for which the condition is satisfied. The idea here is that I would like to change the values one by one (or select one randomly).
df <- data.frame(condition = c(TRUE,TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE),
value = 8:1)
I would like to store this in a new column. Suppose I randomly select row 2: The condition is TRUE and the original value is 7. I change it to 0 (or some other value). The desired output in this case is:
> df
condition value
1 TRUE 8
2 TRUE 7
3 TRUE 6
4 TRUE 5
5 FALSE 4
6 FALSE 3
7 FALSE 2
8 FALSE 1
I suppose I could do this with an if statement, a third column of group-row-numbers and the sample function, but is there a nicer way? In particular, I need to make sure I do not generate a new column in case the condition is not satisfied for any of the values. Otherwise I am wasting a lot of computing time later on in the analysis. I usually do things inside the tidyverse if I can, but I do not mind if there is a nice solution without using the package (or using a different package). Thanks!
I'm doing an application where I have the following scenario:
I have several rules (business classes)
where they all return the client code. They are separate classes that will look for the code trial and error, if find the client code returns it and so on.
How can I use a rule without using a bunch of IFs or threaded IFs in the class that calls the others that contains the specific business rules?
For the specific classes, I used the design pattern strategy.
EX: Main Class
public abstract class Geral
{
public abstract string retornaCodigo(Arquivo cliente)
{
var codigo = ""; // logica
return codigo;
}
}
//Classe derivada 1
public class derivada1 : Geral
{
public override string retornaCodigo(Arquivo cliente)
{
var codigo = ""; // logica
return codigo;
}
}
//Classe derivada 2
public class derivada2 : Geral
{
public override string retornaCodigo(Arquivo cliente)
{
var codigo = ""; // logica 2
return codigo;
}
}
//Classe derivada 3
public class derivada3 : Geral
{
public override string retornaCodigo(Arquivo cliente)
{
var codigo = ""; // logica 3
return codigo ;
}
}
//Classe de Negocio
public class Negocio
{
public string Codigo()
{
var arquivo = new Arquivo();
var derivada1 = new derivada1().retornaCodigo(arquivo);
var derivada2 = new derivada2().retornaCodigo(arquivo);
var derivada3 = new derivada3().retornaCodigo(arquivo);
if (derivada1.Equals(null))
{
return derivada1;
}
if (derivada2.Equals(null))
{
return derivada2;
}
if (derivada3.Equals(null))
{
return derivada3;
}
return "";
}
}
what I wanted and that I did not have to use Ifs in the Business class for validation whether or not I found the code where it can fall under any condition gave example of 3 classes plus I have more than 15 conditions and can increase, case would be many Ifs.
In my C# application i am using linq. I need a help what is the syntax for if-elseif- using linq in single line. Here is the code:
var Date1 = RangeData.ToList();
foreach (var tr in Date1)
{
int id =0;
if (tr >0)
{
id =1;
}
else if (tr >3)
{
id =2;
}
if (id > 0)
{
//
}
}
Someone pointed out a missing semicolon in a simple shell script and I'm curious why it's not throwing a syntax error.
Full script:
interval () {
INTERVAL="$*"
WHEN_TO_RUN=0
while read LINE; do
if (( $(epoch 0S) >= $WHEN_TO_RUN )) then
echo $LINE
WHEN_TO_RUN="$(epoch $INTERVAL)"
fi
done
}
line in question:
if (( $(epoch 0S) >= $WHEN_TO_RUN )) then
I'm also confused as to why the parens make that line work, when I'd normally expect:
if [ $(epoch 0S) -ge $WHEN_TO_RUN ]; then
on OSX if relevant
I am new in python and using Spyder for scripting. I have some python codes for nested if-else (multiple statements). But the problem is same code may give different outputs if someone shifted the codes. Following is an example of that kind of situation.
num1 = -1
num2 = -2
if(num1 > 0):
if(num2 < 0):
print("num1 +ve")
print("num2 -ve")
elif(num2 < 0):
print("num1 -ve")
print("num1 -ve")
else:
print("num1 -ve")
print("num2 +ve")
# num1 -ve
# num1 -ve
if(num1 > 0):
if(num2 < 0):
print("num1 +ve")
print("num2 -ve")
elif(num2 < 0):
print("num1 -ve")
print("num1 -ve")
else:
print("num1 -ve")
print("num2 +ve")
# num1 -ve
# num2 +ve
Can I use any parenthesis or something like that so that code shift do not effect the output?
I have an array, of type myClass, got (status, description_1, description_2, .. till 6, duration_1 ... till 6, fromDay_1 to 6, toDay_1 to 6 fromTime_1 to 6 toTime_1 to 6) these data all in String format: data Example:
"status" : "present",
"description1": "2P MTR M-F 7:30-16:00",
"description2": "2P MTR M-F 18:30-20:30",
"description3": "2P MTR SAT 7:30-20:30",
"description4": "2P SUN 7:30-18:30",
"duration1": "120",
"duration2": "120",
"duration3": "120",
"duration4": "120",
"endtime1": "16:00:00",
"endtime2": "20:30:00",
"endtime3": "20:30:00",
"endtime4": "18:30:00",
"fromday1": "1",
"fromday2": "1",
"fromday3": "6",
"fromday4": "0",
"starttime1": "07:30:00",
"starttime2": "18:30:00",
"starttime3": "07:30:00",
"starttime4": "07:30:00",
"today1": "5",
"today2": "5",
"today3": "6",
"today4": "0"
I have a 3000 data set. I need to output a different result for each set for example :
if (current time between fromTime_1 and toTime_1) and (current week day between fromDay_1 and toDay_1) output: description_1 else if (current time between fromTime_2 and toTime_2) and (current week day between fromDay_2 and toDay_2) output: description_2. and so on for all the 6 conditions.
The other part is I also wanted to display different img on the screen for below conditions:
if (current time between fromTime_1 and toTime_1) and (current week day between fromDay_1 and toDay_1) and status = Unoccupied "but i need to check if the status is = present" and duration_1 = 15 "but duration might be 60 or 120 or 240 and that is output a different img in regarding to the time and the status" output: imgGreen
else if ... same for all 6 conditions. What is the best way to filter my data, I have not much experience in this type of data filtering so please help. Thanks in advance.
