df <-
Name DDay
1 Item1 5
2 Item2 3
3 Item3 3
4 Item4 1
5 Item5 1
6 Item6 1
Logic is:
For (i in seq(from=0, to=5, by=1){
If Dday == i
Print Corrensponding Name (Targets)
I've tried
for (i in seq(from=0, to=5, by=1)){
if(df$Dday == i){
print(df$Name)
}
Full of errors. How can I write this logic in R code?
Thank you.
I am having trouble getting the program to print either "Fruit", "Drink", or "Unknown" (followed by a newline) depending on the value of userItem. I have also tried switching (userItem == x) to (GroceryItem == x) and still no luck. I am stuck understanding on what my error is.
My Code:
import java.util.Scanner;
public class GrocerySorter {
public enum GroceryItem {GR_APPLES, GR_BANANAS, GR_JUICE, GR_WATER};
public static void main (String [] args) {
GroceryItem userItem = GroceryItem.GR_APPLES;
if (userItem == GR_APPLES) {
System.out.println("Fruit");
}
else if (userItem == GR_BANANAS) {
System.out.println("Fruit");
}
else if (userItem == GR_JUICE) {
System.out.println("Drink");
}
else if (userItem == GR_WATER) {
System.out.println("Drink");
}
else {
System.out.println("Unknown");
}
return;
}
}
Errors:

I am trying to accept user input for two people's hourly wage and the amount of hours of overtime they work per year.
using an algorithm I have researched, the program will tell both people the amount of money they make per year and the amount of taxes they pay, which is based on the amount that they make.
This is all fine and dandy. However, what I am now trying to do is to add a line at the end of the program which states who is paying more taxes. This would be accomplished with the method whoPaysMoreTaxes, but I have no idea what to include in that method. I know I would need a simple if/ else if/ else statement to get the job done, but I do not know how I would go about storing the taxes of person 1 and the taxes of person 2 and compare them. The output should be as follows I believe. The numbers 22, 100, 58, and 260 are user input:
Person 1's hourly wage: 22
Person 1's overtime hours for the year: 100
You will make $45540 this year
And you will pay $9108 in taxes
Person 2's hourly wage: 58
Person 2's overtime hours for the year: 260
You will make $133980 this year
And you will pay $40194 in taxes.
Person 2 is paying more taxes.
The issue I am having is finding a way to produce that final line that says who is paying more taxes.

This question already has an answer here:
I'm having trouble with this for some reason. Basically i'm trying to make it so that one person can go through. If the users name is equal to "Megan" "Renae" then the output will be Hello, "Megan" "Renae" but if there is anything else I want it to output I do not know you. I know this is probably something extremely simple and it is just going over my head but if someone could help you would stop my hair from turning grey! Thank you in advance to anyone that responds.

We have a template for item fulfilments that only works for the first 2 scenarios, (1 Complete & 2 partial);
1 Complete fulfilment for Sales Orders
2 Partial fulfilments for Sales Orders
1st fulfilment (shows all SO items, shows qty shipped + qty backorders)
2nd/final fulfilment (shows remaining SO items, shows qty shipped)
3 (or more) Partial fulfilments for Sales Orders - PROBLEM SCENARIO
1st fulfilment (shows all SO items, shows qty shipped + qty backorders)
2nd fulfilment (shows all SO items, shows qty shipped + qty backorders)
etc. other partial shipments, same as above
Final fulfilment (shows remaining SO items, shows qty shipped)
Any order that has 3 or more partial shipments does not work. So, I want to completely re-write the list-item section of our fulfilments but I need some help with the code. This is the basic outline of what we need;
<#if record.item?has_content>
<#list record.item as item>
<#list salesorder.item as tranline>
<#if tranline.line==item.orderline>
<tr>
<!-- item ID --><td>${tranline.item}</td>
<!-- U.O.M --><td><#if tranline.units=="">Unit<#else>${tranline.units}</#if></td>
<!-- Sales Order Qty --><td><#if tranline.quantityfulfilled==tranline.quantity>${item.quantity?c}<#else />${tranline.quantity?c}</#if></td>
<!-- Fulfilled Qty --><td>${item.quantity?c}</td>
<!-- Backorder Qty --><td><#if (tranline.quantity-tranline.quantityfulfilled)?int==0> <#else />${(tranline.quantity-item.quantity)?int}</#if></td>
<!-- Column Spacing --><td> </td>
<!-- Item Description--><td>${item.description}</td>
</tr>
<!-- Items Unfulfilled/On Backorder -->
<!-- this is what I need help with -->
<!-- table layout set out similar to above -->
<!-- but including the header before list -->
<th>The following items are on Backorder:</th>
<tr>
<td><!-- item ID --></td>
<td><!-- U.O.M --></td>
<td><!-- Sales Order Qty --></td>
<td><!-- column spacing --></td>
<td><!-- Backorder Qty --></td>
<td><!-- column spacing --></td>
<td><!-- Item Description--></td>

I would like to check if attr.title (or cell.id) == any of the elements in an array called 'datoer', which is defined in my component.

Is this possible? If you need more code samle to understand my problem, just ask.
So I am developing this app, where there is a textfield, and when you write on it, it is taken to the next SecondviewController. However, if nothing is written on the textfield and you press "Done" button, it should give you an error.
For this I have made an IBOutlet for the NSTextField as this:
@IBOutlet var weblinklabel: NSTextField!
Then this 'done' button contains an IBFunction with the following if statement:
@IBAction func actionWeblinklabel(_ sender: Any) {
if weblinklabel != "" {
self.view.window?.close()
} else {
label1.isHidden = false
}
Whatever is written in webllinklabel should be compared with an empty string, if weblinklabel has something in it then it should just close the current viewController otherwise it should give me a label (label1).
When I do this, I get this error:
Binary operator '!=' cannot be applied to operands of type 'NSTextField!' and 'String'
What am I doing wrong with my code. Thanks in advance! :)
I've been given a question:
Write a piece of Python code that prints out one of the following messages:
"string involved" if either varA or varB are strings
"bigger" if varA is larger than varB
"equal" if varA is equal to varB
"smaller" if varA is smaller than varB
Here's my solution:
if type(VarA) == str or type(VarB)==str:
print("string involved")
elif varA>varB:
print("bigger")
elif varA==varB:
print("equal")
else:
print("smaller")
This looks exactly the same as the given answer, but it is incorrect, and I think it has something to do with my indentation. For some reason, after the if statement on the first line, the shell doesn't automatically indent the next line automatically. Why is this? I had to press TAB after each line. Also, what exactly is wrong with the code that I've written?
Anyone know how to check similar strings in the if...else statement?
My code below is to check whether a user is in the custom restricted permission group so the system can allow/decline the access.
if ((myMemberships.indexOf(Sitetitle + " Restricted Readers")>=0) {
oInstance.model.dcn[0]._recordSet[i].isMember=false;
But I want to write an array that will store different string combinations of Sitetitle + " Restricted Readers" such as SiteTitle restricted reader(s), SiteTitleRestrictedReader(s), SiteTitle restrict reader(s). So I can prevent administrators typing the group name wrong when they create the group name, and eventually cause the code fail.
in c# i want to return IEnumerable with column with name isedit
my type of innerResult is IEnumerable
but i have error Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'System.Collections.Generic.IEnumerable'. An explicit conversion exists (are you missing a cast?)
innerResult = (from f in innerResult
select new
{
isedit = (bool?)Convert.ToBoolean(((APS_WorkFlow_Activities).Contains(f.Field<Guid>("ActivityID")) ? false : true))
});
I am new here. I have a problem with my if/else if statement.
I got this:
if (unalumno.notas >= "90" && unalumno.notas <= "100") {
unalumno.notas = "A";
} else if (unalumno.notas >= "80" && unalumno.notas <= "89") {
unalumno.notas = "B";
} else if (unalumno.notas >= "70" && unalumno.notas <= "79") {
unalumno.notas = "C";
} else if (unalumno.notas >= "60" && unalumno.notas <= "69") {
unalumno.notas = "D";
} else if (unalumno.notas <= "59") {
unalumno.notas = "F";
}
All the else if statement is giving to me the right result in letters, but the first if continue giving the result in numbers. Hope can understand me. Sorry for english lol
Have a good day
Ok so I have a block of code in WordPress that has "OR" conditions inside of the "elseif" statement. here is the code:
<?php } elseif($index == 1 || $index == 8 || $index == 9 || $index == 16 || $index == 17 || $index == 20 || $index == 21) { ?>
So the code works great up until $index == 20 || $index == 21
Is there a limit on how many times I can use || in the elseif statement?
this linq must create column with name isedit and value false but it doesn't create
innerResult.Select(f => new
{
isedit = false
});
I’m new to R and i’m trying to learn fundamentals. I’m facing a small problem for which i can’t find a solution online.
What i want to do: write a function to lower case for all the columns in my data.frame if they respect a condition (class = factor)
This code works, but for all my columns :
lower = function(x) {data.frame(tolower(as.matrix(x)))}
I need more something like this, but it doesn’t work:
lower = function (x) { for (i in 1:length(x)) {
if (class(i)=="factor") {
data.frame(tolower(as.matrix(x)))
}
}}
x is my data.frame
Thank you

Hey guys I'm really new to sheets so thanks for the help! I'm working on some inventory data where I need to differentiate between left hand and right hand products. Basically I want to find a certain character in an cell, and if true it will return Left Handed or Right Handed or nothing if it doesn't apply. The return value would appear on a different cell. I'm trying something like this, hope it makes sense:
IF(FIND(" lh",a1)), Left Handed, "")
I want if cell has character (space)lh, true renturn Left Handed, false return blank. I had a different variation of the aforementioned formula yesterday where it worked in returning left Handed but got #Value! when " lh" was not in the name. After this hump I also need to incorporate two of statements in one formula for Right Handed and Left Handed. I hope all this makes sense, again thanks for the help. I'm in a cab right now and will provide a picture of my sheets once I get to work.
My Else statement is always being executed as well as the if statement.
If i log in as user 2 and any of the if or else-if statements are correct it will do that section of code but then it will always print "You can't send money to yourself" also.
Can anybody see what I've done wrong here as I've looked for the last 2 hours and can't see whats causing this?
if (loggedInUser == 2 && TaccountNumberTBox.Text == accountNo && TsortCodeTBox.Text == sortCode && amount <= balance2)
{
int bal;
Int32.TryParse(TamountTBox.Text, out bal);
balance2 = balance2 - bal;
balance = balance + bal;
MessageBox.Show("Funds sent");
history = history + "£" + amount + " Sent to " + TnameTBox.Text + "\n";
historyLbl.Text = history;
}
else if (loggedInUser == 2 && TaccountNumberTBox.Text != accountNo | TsortCodeTBox.Text != sortCode)
{
MessageBox.Show("The account you want to transfer to does not exist.");

x = x * 2;

Output according to me should be
x is less than y
x is equal to y
x is equal to y
But the actual output is
x is less than y
x is equal to y
x is greater than y
Please explain me how is it possible?

I've been doing some research online and toying around with my code, but I can't seem to figure out how to create an if statement for my shapes created using tkinter-canvas.
It's difficult to word this correctly, but I would like to know how to create a condition where if two of my shapes enter the same coordinate area, I can make something happen.
How would you identify your shape or tags = " " in the statement? Would you create a boolean statement for if it is in a certain coordinate range?

I'm trying to run a check against two arrays (one has 4 objects, one just have a few strings) with for loops and if statement for a problem set.
The idea is to use for loop to iterate over every element in the object array and the string array, then use if statement to figure out matches and shove the matching string into a new array. Once all the elements are iterated, it returns the string if there is a matching one.
The problem is the function calls it a day once a single match in the object array is found and returns that only that instead of iterating over the rest of the elements in the object array.
var passengers = [
{ name: ["Michael Jackson"], paid: true },
{ name: ["Osama"], paid: false },
{ name: ["Harambe"], paid: true },
{ name: ["Pepe"], paid: true },
];
var noFlyList = ["Jimmy", "John", "Pepe", "Osama"];
function checkNoFly(passengers, noFlyList) {
for (var i = 0; i < passengers.length; i++) {
for (var j = 0; j < noFlyList.length; j++) {
if (passengers[i].name[0] == noFlyList[j]) {
var passengerList = [];
passengerList.push(passengers[i].name[0]);
return passengerList;
}
}
}
return true;
}
function processPassenger(passengers, testFunction) {
for (var i = 0; i < passengers.length; i++) {
if (testFunction(passengers[i])) {
return false;
}
}
return true;
}
var allCanFly = processPassenger(passengers, checkNoFly);
if (!allCanFly) {
console.log("We cannot fly because " + checkNoFly(passengers, noFlyList) + " is on the no-fly list");
}
I'm having some unexpected errors in achieving the following functionality. In this example code, I have the temperature on several days of the week. For this generalized example, I'm interested in determining the days that are 72,74, or 65 degrees. As an output, a variable should be created that contains the day of the week that is within this temperature range. Also, please note that in these data there is only ever 1 day that would fall within have one of these temperatures.
Monday Tuesday Wednesday Day of Interest
72 78 80
61 78 74
Monday Tuesday Wednesday Day of Interest
72 78 80 2
61 78 74 4
I wrote the following code, with the generous help of the great folks here at StackOverflow,
IF (Monday = 65 OR 72 OR 74) Day_Of_Interest = 2.
IF (Tuesday= 65 OR 72 OR 74) Day_Of_Interest = 3.
IF (Wednesday = 65 OR '72' OR 74) Day_Of_Interest = 4.
IF (Thursday = 65 OR 72 OR 74) Day_Of_Interest = 5.
but sadly it returns an error:
IF A relational operator may have two numeric operands or two character
string operands. To compare a character string to a numeric quantity,
consider using the STRING or NUMBER function.'
I tried changing the code to be akin to '65' OR '72', but this produced another error. I would really appreciate if anyone had any thoughts on how to make this work. I know the example above isn't the best, but it's the best I could think of. If you need anymore details I'd be more than happy to oblige. Thanks so much for your help!

I have the following sequence:
seq = [['ATG','ATG','ATG','ATG'],['GAC','GAT','GAA','CCT'],['GCC','GCG','GCA','GCT']]
Here is a dictionary key that stores the value of amino acid for each of the codons (Triplet bases like ATG, GCT etc).
aminoacid = {'TTT' : 'F','TTC' : 'F','TTA' : 'L','TTG' : 'L','CTT' : 'L','CTC' : 'L','CTA' : 'L','CTG' : 'L','ATT' : 'I','ATC' : 'I','ATA' : 'I','ATG' : 'M','GTT' : 'V','GTC' : 'V','GTA' : 'V','GTG' : 'V','TCT' : 'S','TCC' : 'S','TCA' : 'S','TCG' : 'S','CCT' : 'P','CCC' : 'P','CCA' : 'P','CCG' : 'P','ACT' : 'T','ACC' : 'T','ACA' : 'T','ACG' : 'T','GCT' : 'A','GCG' : 'A','GCA' : 'A','GCG' : 'A','TAT' : 'Y','TAC' : 'Y','TAA' : 'STOP','TAG' : 'STOP','CAT' : 'H','CAC' : 'H','CAA' : 'Q','CAG' : 'Q','AAT' : 'N','AAC' : 'N','AAA' : 'K','AAG' : 'K','GAT' : 'D','GAC' : 'D','GAA' : 'E','GAG' : 'E','TGT' : 'C','TGC' : 'C','TGA' : 'STOP','TGG' : 'W','CGT' : 'R','CGC' : 'R','CGA' : 'R','CGG' : 'R','AGT' : 'S','AGC' : 'S','AGA' : 'R','AGC' : 'R','CGT' : 'G','GGC' : 'G','GGA' : 'G','GGG' : 'G',}
As one can see several codons can code for the same aminoacid (eg. GGT,GGC,GGA, GGG etc all code for Glycine (G) ). These are Synonymous (PSyn) and if codons code for different amino acids they are Non-Synonymous (PNonsyn)
In this code, I need to do the following:
For each element in the list of lists, if there is a change in the bases AND they all code for the same amino acid, then increase count of PSyn by 1 and if it codes for different amino acids increment count PNonsyn by 1
Here,
ATG all code for M #However, all are ATG's no change in bases. So no increment in count
GAC, GAT for D; GAA for E; and CCT for P #Codes for three different amino acids, increment count by 1
GGT,GGC,GGA, GGG for G #Different bases but all code for same amino acids, increment count by 1
OutPut: CountPsyn = 1 CountPNonsyn = 1
Generate a list of amino acids that corresponds to the above seq. such that:
Output : ['ATG','nonsyn','G'] #For sites with different aminoacids, the list should say nonsyn and for sites which had identical bases it should list the bases
I need help modifying the following code to get the program to work. I am not confident on how to call values from dictionary and check them against all the elements. Code Attempted:
countPsyn = 0
countPnonsyn = 0
listofaa =[]
for i in seq:
for base, value in enumerate(i):
if value[i] == value[i+1]: #eg. ['ATG','ATG','ATG','ATG']
listofaa.append(value)
if value[i] != value[i+1]:
if aminoacid[value][i] == aminoacid[value][i+1]: #eg.['GCC','GCG','GCA','GCT']
countPsyn =+ 1
listofaa.append(aminoacid)
else: #eg. ['GAC','GAT','GAA','CCT']
countPnonsyn =+ 1
listofaa.append('nonsyn')
File Output can be found [here][1]
Objective of program:
Program that requires the user to enter two passwords that are the same.
The password must be at least 8 characters long.
The password must contain at least:
- ONE alpha character
- ONE numeric character [0-9]
- ONE character that is not alpha or numeric, such as: ! @ $ % ^ & * ( ) - _ = + [ ] ; : ' " , < . > / ?
The password MUST NOT:
- contain spaces;
- begin with an exclamation [!] or a question mark [?];
- contain repeating character strings of 3 or more identical characters, such as “1111” or “aaa”.

My problem:
The program allows me to enter three or more identical characters, when it shouldn't.
So I can't seem to find out what is wrong with my code, Its good, i checked but it seems not to work. everything left out of what is shown is correct because i tested it before, so, well, here's my code...
1 = Stay 2 = Go 3 = South ''') while True: choice = raw_input("->") if choice == 1: time.sleep (2.5) '<' + str(Pname) + '> Lets Stay Here For Tonight' time.sleep (2.5) '<' + str(NPCChester) + '> But we have no other choice, we have nothing so we have to go out and find stuff as fast as possable!' time.sleep (2.5) '<' + str(NPCAnnabeth) + '> On the other hand, we have nothing so we should play it safe right?' time.sleep (2.5) '<' + str(NPCChester) + 'Fine...' time.sleep (2.5) break elif choice == 2: '<' + str(Pname) + '> Well, Lets Just Go' time.sleep (2.5) '<' + str(Pname) + "> But we should play it safe right after we lost everything because we're not prepared right?" time.sleep (2.5) break elif choice == 3: '<' + str(Pname) + '> How About We Go South' time.sleep (2.5) '<' + str(NPCAnnabeth) + "> But we're still going some where anyways I want to stay" time.sleep (2.5) '<' + str(NPCChester) + "well, we have tot go soo" break else: print "That Is Not A Choice" continue
So I know that the correct way is:
if (x > y)
{
//...
}
else if (x = y)
{
//...
}
else
{
//...
}
Or for example if I want specific condition for last condition:
if (x > y)
{
//...
}
else if (x = y)
{
//...
}
else
{
if (x < y)
{
//...
}
}
But if it is wrong, like this one:
if (x > y)
{
//...
}
else if (x = y)
{
//...
}
else if (x < y)
{
//...
}
My question is why last one is wrong and what kind of failure it can cause?
For example, can it be cause of multiplication of process in last condition in if-statement?
So I am in the process of developing this app for Mac and I am using Swift. I am just learning + developing the app side by side. I have the main viewController and when you press (+) button, it opens another viewcontroller with textfield. Now i have two buttons, one says "Done" and the other says "Cancel". If you press Cancel the viewController dismisses. However, if you press "Done" then whatever you added in that textfield appears in the first ViewController.
I want to run an if statement on "Done" button. So if you haven't written anything in the textfield and you press done, it gives you an error, and if you have written something, then it allows you to press Done and it dismisses!
I created an IBOutlet for the textfield:
@IBOutlet var weblinklabel: NSTextField!
Then whatever is stored in the weblinklabel is stored in another variable:
weblinklabel.stringValue = done!
Obviously, "done" is an optional string variable, assigned as this:
var done: String? = ""
Now in my understanding, "done" variable if empty should give the error which in this case is a label that shows itself(which is isHidden = false' in viewdidload()) function initially.
This is the "if-statement" that I am trying to use:
if done != nil {
self.view.window?.close()
}
else {
label1.isHidden = false
}
I believe the placement of this code isn't right. I am placing it under IBAction of the "Done" button.
Any help in this regard, will be appreciated! thanks
I've got the following code where:

I have strange problem with a simple c program.
#include<stdio.h>
#include<math.h>
#include<conio.h>
main() {
int a, b, c, delta;
float x1, x2;
printf("Please Enter a,b,c :");
scanf("%d%d%d",&a,&b,&c);
delta = (b * b) - (4 * (a * c));
if(delta < 0){
printf("No roots!");
}
else{
if (delta >= 0){
x1 = (-b + sqrt(delta)) / (2 * a);
x2 = (-b - sqrt(delta)) / (2 * a);
}
}
printf("r1=%f and r2=%f", x1, x2);
getch();
}
when I enter 2 1 1, it seems, the program executes both if and else in line 10 and 13. The output is No roots!x1=0.0000 and x2=0.0000 what's wrong?
I have a table with approximately 3000 rows with data in the form of :
Number Type
10001 0
10005 7
10006 0
10007 14
10012 16
10022 14
10023 0
10024 0
10029 7
10035 17
10045 14
I want to add a third column so that the table looks like :
Number Type SCHEach
10001 0 0
10005 7 0
10006 0 0
10007 14 0
10012 16 1
10022 14 0
10023 0 0
10024 0 0
10029 7 0
10035 17 1
10045 14 0
where values in the SCHEach column are based on values in the Type column. If values in the Type column are 16,17,21, or 22, values in the SCHeach column should be 1. For any other values in the Type column, SCHEach values should be 0.
Right now I'm using the following
library(dplyr)
schtable$SCHEach = ifelse(
schtable$Type == 16 |
schtable$Type == 17 |
schtable$Type == 21 |
schtable$Type == 22, 1, 0)
I am new to R and wanted to know if there is a way to do it without having to type the following separately for 16,17,21,and 22?
schtable$Type == 'number'
I am trying to pass a pointer through this for loop but it doesn't work. This is just a block from my original code. I didn't want to overload you all with 200 lines of code! If you need all of it please ask.
Ok! so I used 3 printf's to see how far my code gets before it crashes. It gets to the printf( "2" ); before it crashes. So I am assuming it is something to do with "if ( *(userInput + i ) == sNumArray[j] )" I am not sure what I am doing wrong. As far as I know pointers dont use pointer[i] to cycle through each element they use *( pointer + i )?
I only started programming with c 4 weeks ago so sorry if I didn't explain this thoroughly. I am still learning the terminology etc
for ( i = 0; i < sUserInput_SIZE; i++ ) {
printf( "1" );
for( j = 0; j < sNumArray_SIZE; j++ ) {
printf( "2" );
if ( *(userInput + i ) == sNumArray[j] ) {
validInput++;
printf( "3" );
}//End if( )
}//End inner for( )
}//End outer for( )
This question already has an answer here:
I have an if statement here and there are no errors but it gives the wrong result:
Initial Code
import java.util.Scanner;
public class Decision {
public static void main(String args[]){
String enter;
Scanner inputanswer = new Scanner(System.in);
System.out.println("welcome to a test");
System.out.println("proceed? yes or no?");
String decision1 = inputanswer.nextLine();
if ( decision1 == "yes" ){
System.out.println("lets proceed");
} else if ( decision1 == "no" ){
System.out.println("Quitting now");
} else {
System.out.println("invalid");
}
}
}
so when I type in yes or no for example it still comes out as invalid.
Also can someone help me put this in a loop so that when they do an invalid statement it resets to the question.
I wrote the following script trying to calculate portions in array a and stack the result to the original array:
import numpy
a = numpy.array([[1, 4, 4.555],
[2, 3, 9.112],
[3, 1, 7.322],
[1, 5, 3.911]])
i = 0
b = numpy.ones((4,1))
if i <= 2:
b[i][0] = float(a[i][2])/(a[i][2]+a[i+1][2])
b[i+1][0] = float(a[i+1][2])/(a[i][2]+a[i+1][2])
i = i+2
print b
c = numpy.hstack((a,b))
print c
But the result were strange:
array b:
[[ 0.33328455]
[ 0.66671545]
[ 1. ]
[ 1. ]]
array c:
[[ 1. 4. 4.555 0.33328455]
[ 2. 3. 9.112 0.66671545]
[ 3. 1. 7.322 1. ]
[ 1. 5. 3.911 1. ]]
The first and second rows of array c was what I want, but the rest rows were strange. The result array I expected is:
[[ 1. 4. 4.555 0.33328455]

How to fix this? And is there more efficient coding to do this task?
I have the following code:
<form action='' method='POST' id='form1'>
imdbcode : <input type='text' id='imdbcode' name='imdbcode' /><br/>
<input type='submit' name='submit' value='Get'/>
</form>
<?php
if(isset($_POST['submit'])){
.
.
.
$title = ... ;
echo "
<form action='' method='POST' id='form2'>
<input type='submit' name='Send' value='Send'/>
</form>";
}
if(isset($_POST['Send'])){
//I WANT TO USE $Title from condition1
} ?>
I want to use $title in second condition.
It prints $title in first condition! But doesn't print after closing condition!
How can I do that?
It was first time to join developer forums (CMIIW) to learning coding for my college. C++ Builder 6 was used in my department
So I had learning simple login forms, but I want to try to make "Login" button accessing another forms (or .cpp) such database system if login successful ("if" code) and I don't know what code for this. I had find this but I cannot figure it (because I am new student and I never know about app coding).
For example, login.cpp --> Press "login" --> "If-statement" --> "ShowMessage" --> database.cpp
What's code for accessing another form in "if-statement"?
Thanks :)
Sorry for my bad English
This question already has an answer here:
How can you have user input a certain string and have a certain response? This is a piece of code I'm working on...
import java.util.Scanner;
public class AppetizerInformation {
public static void main(String[] args) {
System.out.print("Please enter an appetizer: ");
Scanner userFoodInput = new Scanner(System.in);
String appetizer = userFoodInput.next();
if (appetizer = "Potato") {
System.out.println("Good");
}
}
}
I'm trying to build a simple program that asks for a grade whether it is numerical or general weighted average e.g. 75, 1.5 respectively. And when the user input a non numerical number a stated in the if condition, it prints error as stated also in the else condition. The problem is when I enter a 3-digit,4 , 5 digit number and so on, I get an error that is supposed to be Grade is not within the scope as stated in the nested if (else inside the if condition). Also the same thing happens when I enter 0. But the good thing is, when I enter a negative number or integer, it properly works well. Can I ask what is the problem with my condition? (Tnx in advance)
#include <iostream>
using namespace std;
int main ()
{
double grade;
cout<<"Enter Grade or GWA: ";
cin>>grade;
if (grade!=grade>='a'&&grade<='z'||grade!=grade>='A'&&grade<='Z')
/*The first If condition states that the user will get an error if
input a non-numerical integer or number.*/
{
if (grade<=5&&grade>=1)
{
if (grade>2.5)
cout<<"Failed"<<endl;
else
cout<<"Passed"<<endl;
}
else if (grade<75&&grade>=0)
cout << "Failed" << endl;
else if (grade>=75&&grade<=100)
cout << "Passed" << endl;
else
cout<<"Grade is not within the scope!"<<endl;
}
else
cout<<"Error!"<<endl;
cin.get();
return 0;
}
I normally use python for large (or cross platform) things and BASH for small things. I love the BASH syntax, so I really hate the fact that python doesn't use (curly) brackets/braces to enclose things like if statements. Is there a language with similar functionality to python that uses (curly) brackets/braces?
Example:
What I want:
if x=1 {
do something
}
What python has:
if x=1:
do something
There are given lots and I'm suppose to print out all letters, either uppercase or lower case. I'm also not allowed to use any built in functions. I'm having difficult printing out the list of letters. All i get in return is an empty closed bracket.
alphabet = "abcdefghijklmnopqrstuvwxyz"
alphabet2 = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
def get_symbols(lot):
list = []
for i in lot:
if (i == alphabet or i == alphabet2):
list.append(lot);
return list
The given lot:
lot1 = [['.', '.', 'a', 'D', 'D'],
['.', '.', 'a', '.', '.'],
['A', 'A', '.', 'z', '.'],
['.', '.', '.', 'z', '.'],
['.', '.', 'C', 'C', 'C']]
My output:
Traceback (most recent call last):
File "tester4p.py", line 233, in test_get_symbols_2
def test_get_symbols_2 (self): self.assertEqual (get_symbols(lot1()),['a','D','A','z','C'])
AssertionError: Lists differ: [] != ['a', 'D', 'A', 'z', 'C']
Second list contains 5 additional elements.
First extra element 0:
'a'
- []
+ ['a', 'D', 'A', 'z', 'C']
Expected Output:
['a', 'D', 'A', 'z', 'C']
I'm having difficulty starting a while loop trying to generate a program that will generate a pie chart or bar graph from numbers that a user will input. How does the while loop need to be written so it's not looping forever? I know I could use a for loop for a finite sequence but i'm not too experienced in that. any guidance would be helpful!
from SimpleGraphics import *
print("Chart Menu: 1.Pie Chart, 2.Bar Chart")
chart = int(input("enter either 1 for pie chart or 2 for bar chart:"))
if chart == 1:
title = input("Enter the title of the chart: ")
numSec = int(input("Enter the number of sectors: "))
tSum = int(input("Enter the total sum of all sector values: "))
gsize = int(input("Ehter the grid size (Between 10 and 400): "))
yLabel = input("Enter the label for the Y-Axis:")
while loop
-the name of each sector
-the value each sector
-draw pie chart
if chart == 2:
title = input("Enter the title of the chart: ")
numCat = int(input("Enter the number of categories: "))
grid = int(input("Ehter the grid size (Between 10 and 400): "))
while loop
-name of each category
-value for that category
-draw bar graph
So what i'm trying is to do a specific task from the answer of the two options, here's some of the code, but i don't know what's going on here.
String[] sex = { boy, girl };
JOptionPane.showOptionDialog(null,"Hey " +output1 +". Are you a boy or a girl?", "Question",
JOptionPane.YES_OPTION, JOptionPane.NO_OPTION,
null, sex, sex[0]);
if(sex == JOptionPane.YES_OPTION)
{
I'm preparing for an exam that's coming up soon about python and seem to have gotten stuck with a task.
The task says as follows:
Data is received as a stream of characters:
A typical character sequence is:
**ali#thomas#ghandi#akmar#smith#barija**
Write program code to:
input a character sequence (made up of one or more surnames
check that the character sequence has a valid format
calculate and output the number of surnames*
If anybody out there would be kind enough to help me out, even if it's just a little bit, I would be very grateful.
Thank you all very much for your time.
Cheers, Ben
I have this C program almost all completed. Option 1 asks the user to enter a fraction and then option 2 displays that fraction. option 3 sorts the fractions in ascending order, option 4 finds the min, median and max of my set of fractions. However. If the user selects option 4 before sorting the fractions, then a "Please sort the values first" should pop up. I know to add the if statement but not sure what the statement would be.
This is my code:
//This is my code:
#include <stdio.h>
#include <stdlib.h>
//Struct to hold fraction data
typedef struct fraction
{
int numerator, denom;
}fraction;
double Calc_Frac(fraction b)
{
return((double)b.numerator / b.denom);
}
int main()
{ fraction arrFraction[100];
int i = 0;
int j;
int num = 1;
while (num == 1)
{
int choice;
printf("\nPress 1 to enter a fraction\n");
printf("Press 2 to view stored fractions\n");
printf("Press 3 to sort fractions\n");
printf("Press 4 to find min max median fraction\n");
scanf("%d", &choice);
if (choice == 1)
{
//Prompting user
printf("\nEnter your fraction, numerator followed by denominator\n");
//Reading values from user
scanf("%d %d", &arrFraction[i].numerator, &arrFraction[i].denom);
//Incrementing counter
i++;
}
if (choice == 2) {
printf("-------------------------\n");
for (j = 0; j < i; j++)
{
printf("%d %d/%d \n", arrFraction[j].numerator /
arrFraction[j].denom, arrFraction[j].numerator%arrFraction[j].denom,
arrFraction[j].denom);
}
printf("\n-------------------------\n\n");
}
if (choice == 3) {
int min;
fraction tmp;
for (int k = 0; k < i; k++)
{
min = k;
for (j = k + 1; j < i; j++)
{
if (Calc_Frac(arrFraction[j]) < Calc_Frac(arrFraction[min]))
{
min = j;
}
}
tmp = arrFraction[k];
arrFraction[k] = arrFraction[min];
arrFraction[min] = tmp;
}
}
if (choice == 4)
{
if (//the statement ){
printf("please sort values first"\n);
}
else
{
printf("Min fraction is: %d %d/%d\n", arrFraction[0].numerator / arrFraction[0].denom, arrFraction[0].numerator%arrFraction[0].denom, arrFraction[0].denom);
printf("Median fraction is: %d/%d\n", arrFraction[i / 2].numerator, arrFraction[i / 2].denom);
printf("Max fraction is: %d %d/%d\n", arrFraction[i - 1].numerator / arrFraction[i - 1].denom, arrFraction[i - 1].numerator%arrFraction[i - 1].denom, arrFraction[i - 1].denom);
}
}
}
system("pause");
return(0);

Hi all, I have following input:
id <- c("a", "b", "c", "d")
target <- seq(from = 100, to = 400, length.out = 4)
a <- c(300, 304, 100, 405)
b <- c(300, 104, 100, 405)
c <- c(85, 304, 500, 405)
df <- as.data.frame(cbind(id, target, a, b, c))
I would like to add a new column "column" which indicates per row, which of the columns "a", "b", "c" would be the first column with a value smaller than the target solution. The requested output looks like this:
df$column <- c("c", "b", "a", "NA")
df
I thought about a concenated if check per row and apply this to all rows with the apply function. However the abc columns are quite long (round 20, therefore a loop would be required) and the number of rows are about 4.000. Does anybody have an idea on how to solve it? Thanks! Nils
I am trying to iterate through three recent posts and display their thumbnail, title and permalink.
The first one has a slightly different look so there is an if statement as well to display the first one in a different setting and then iterate throguh the rest. What is happening instead, it is showing the first post three times with styling for both if and else.
I am not sure what am I doing wrong, thanks for any help!
<?php
$recent = wp_get_recent_posts( array('numberposts' => 3) );
$i = 0;
global $recent_post;
foreach( $recent as $recent_post ) {
if ($i == 0 ): ?>
<div class="header_recent main">
<a href="<?php the_permalink($recent_post); ?>">
<img src="<?php echo get_the_post_thumbnail($recent_post->ID); ?>"/>
<div class="overlay">
<h1><?php the_title_attribute($recent_post); ?></h1>
</div>

wp_reset_postdata(); ?>
Also, I would really appreciate help with the warning about get_the_post_thumbnail function:

In the code above, I am taking input from scanner and checking to see if my word is in my database. If so I print yup if not no. In my scenario, my else is being skipped. Why is it that my if statement works but when I put in a phony value it does not print no and decrease points?
System.out.println("tag " + status + " - " + status.matches("Not yet synchronized"));
I have this and it returns
I/System.out: tag Not yet synchronized - false
Meaning status value is Not yet synchronized but the condition
status.matches("Not yet synchronized")) return false wherein I expect it should return true.
Why does this happened.
I have the code divided on three functions:
f.m (This function works)
function y=f(x)
y = x^2;
endfunction
df.m (The function that return the derivate of y=x^2. This function works)
function y=df(i)
syms x,diff(f(x),x);
subs(ans,x,i);
y = ans;
endfunction
newton.m (maxIt = max of tries)
function [x1,nIt] = newton (f,df,x0,tol,maxIt)
k=0;
x=x0;
nIt = 0;
while (k<maxIt)
if(df(x)== 0)
fprintf("La derivada, da resultado 0");
k=maxIt;
else
i = x - (f(x)/df(x))
x = i;
nIt = nIt + 1
k=k+1;
endif
end
endfunction
Ok, i execute this comand "newton(@f,@df,0,10,2)", 2/3 of the program works good but if i do df(0), the result of this is 0 but the if dont works. I verify if df(0) return 0 and it´s ok. I´m new in Matlab/Octave. Sorry for the "english".

I was wondering if any of you could help me out with my code. I am struggling to find out how to make a 'lights out' game using only javascript. Attached is my code. My main question is how do I use if or if else statements to make the squares around the one clicked turn yellow. Your help is appreciated.

This question already has an answer here:
I've been trying to figure this out for about 3 hours and I am finally almost done; I just need help with this last part. The problem is as follows: "Write a Java program that simulates the random flipping of two coins. At the start of the program prompt the user for the amount of times to flip the coin. Display each flip, and afterward display the percentages of heads and tails for each coin. Also, display the percentage that both coins were heads, and the percentage both coins were tails." I can't seem to figure out why I keep getting 0's for percentages on all of them.
import java.util.Scanner;
public class prob3
{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many times would you like to flip the coins?");
int n;
n = in.nextInt();
int coin1HeadsCount = 0;
int coin2HeadsCount = 0;
int coin1TailsCount = 0;
int coin2TailsCount = 0;
for (int i = 1; i <= n; i++)
{
int range = 2;
int randomNum = (int) (range * Math.random()) + 1;
int range2 = 2;
int randomNum2 = (int) (range2 * Math.random()) + 1;
if (randomNum == 1 &&
randomNum2 == 1)
{
System.out.println("H H");
coin1HeadsCount++;
coin2HeadsCount++;
}
else if (randomNum == 1 &&
randomNum2 == 2)
{
System.out.println("H T");
coin1HeadsCount++;
coin2TailsCount++;
}
else if (randomNum == 2 &&
randomNum2 == 2)
{
System.out.println("T T");
coin1TailsCount++;
coin2TailsCount++;
}
else if (randomNum == 2 &&
randomNum2 == 1)
{
System.out.println("T H");
coin1TailsCount++;
coin2HeadsCount++;

int total2Heads = (coin2HeadsCount / n);
int total1Tails = (coin1TailsCount / n);
int total2Tails = (coin2TailsCount / n);
int bothHeads = ((coin1HeadsCount + coin2HeadsCount) / n);
int bothTails = ((coin1TailsCount + coin2TailsCount) / n);
System.out.println("Coin 1 was heads " + total1Heads + ", and tails " + total1Tails);

REAL:: counter,smallest
WRITE(*,*) " Counter", " num4"
WRITE(*,*) " --------------------"
DO counter = 0.1,8,0.1

smallest = num4
END IF
IF (num4 < smallest) THEN
smallest = num4
END IF
END DO
WRITE(*,*) "The smallest num4 is:", smallest
STOP
END PROGRAM ONE
The program needs to be ran to understand what I am trying to say.
This finds and displays the lowest "num4" value. What I also do want it to display is the corresponding "counter" value to the "num4" value. That "counter" value will go along with the last WRITE statement. It should say:
WRITE(*,*) "The smallest num4 is:", smallest, "for", counter
The output should be:
The smallest num4 is 640.021 for 7.10000

Still very new to Python, so I apologize if anything in here is off. This is for a program where you enter a number, and get back a value. You have to enter a number, so I'm trying to make it say "different values needed" when the user enters a string. However, I have an int() around the input, which means I get the following error when I input a string:
ValueError: invalid literal for int() with base 10
My code is as follows:
while True:
OVR = int(input('OVR?'))
if OVR == 0:
break
elif OVR < 50:
print('0.75M')
elif OVR >= 50 and OVR < 60:
print('8M')
elif OVR >= 60 and OVR <= 70:
print('15M')
elif OVR > 70 and OVR <= 82:
print('30M')
elif OVR > 82:
print("He's the GOAT, what do you think he wants?")
else:
print('different values needed')
I know it's probably a bad idea to have all those elifs, so I will eventually consolidate that into one formula. As said earlier, my main goal is that I want to make this so that it prints "different values needed" when the user enters a string. I've considered a try/except statement, but if I'm understanding them correctly, they are not really for calculating and printing things, and also couldn't take these elifs.
Below I am asking the user to enter data, now if the user enters all field of data..then I get what i expect in return. Yet I want the user to be able to enter one value and print the entire row containing that one value the user entered. Now i am trying to use if else statements while the values are empty..but it is not working. Can someone tell me a better way?/ why this is not working?

I'm new to Java and at a loss what I'm doing wrong. I'm just trying to save the highscore and then print it.
int max = players[0].getHighScore();
int bestIndex = 0;
String bestName = "testing";
for (int i = 1; i < players.length; i=i+1) {
if (players[i].getHighScore() > max) {
bestIndex = i;
max = players[i].getHighScore();
bestName = players[i].getName();
}
}
System.out.println(bestIndex);
System.out.println(max);
System.out.println(bestName);
The variable max will update for every loop and then print the high score, no problems there. But the two other variables, bestIndex and bestName will just stay with the same value as initiated. I've even tried setting bestIndex and bestName to a constant and a string respectively inside the if statement but they won't change. If I remove the if statement, both will change, but ofcourse then I will just end up with the last entries, rather than the ones corresponding to the high score. So I figure the problem is with the if statement but other than that, I have no clue.

I'm new to JavaScript and I've been trying to make a code that finds the formula of a triangle. My problem is after the if statement I would like to change the value of "Area" but I keep getting undefined everytime I run the code. How do I change the value of a variable within an if statement?
I am currently working with the IBM dashDB and I need to know the sql statement for inserting a new row if this row does not already exist based to certain criteria. So, something like this:
INSERT INTO tablexyz (Col1, Col2, Col3) VALUES (val1, val2, val3) IF NOT EXIST (SELECT * FROM tablexyz WHERE val1 = x, val2 = y)
How can I do this?
