when I type the code in, there is an error saying this:
picture of the error: https://i.stack.imgur.com/ixFaM.png
How can I fix it?
@IBAction func nextQuestionButton(_ sender: Any) {
if (nextQuestionButton.isSelected == true) {
}
The function should display a message in the following format: '{operation} {status}.'
Where {operation} is the value of the parameter passed to this function
and
{status} is 'has started' if the value of the parameter 'value' is 0
{status} is 'is in progress ({value}% completed)' if the value of the parameter 'value' is between,
but not including, 0 and 100
{status} is 'has completed' if the value of the parameter 'value' is 100
Consider the following R input:
if(TRUE){1}else{0} + if(TRUE){1}else{0}
The result is 1, but I was expecting 2. If I enclose each if-else statement in parentheses,
(if(TRUE){1}else{0}) + (if(TRUE){1}else{0})
then the result is 2.
Can someone explain this behaviour?
I want to change the Elevated button color when I press the radio buttons. 1.button -> red, 2.button -> yellow, 3.button -> green. In the Elevated.stylefrom if condition did not work. Just ternary condition works but it is only for one condition. I want to add 3 conditions. I hope it was clear.
Or do I need to create a model for this?

I am new to C++ and would appreciate some guidance. Before I reveal the problem, let me emphatically state that I am looking for GUIDANCE, not an answer; having the answer given to me will not benefit me any! I know other people have asked similar questions on here, but the answers given included coding to which I have not been exposed yet- I'm not trying just to pass the class, I am taking this course to actually learn C++. Ok, here are the instructions:
Write a program whose input is:
firstName middleName lastNameand whose output is:
lastName, firstInitial.middleInitial.
My code is:
if (middleName.size() == 0 ) {
cout << lastName << ", " << firstName[0] << "." << endl; }
else {
cout << lastName << ", " << firstName[0] << "." << middleName[0] << "." << endl; }
I have the closing } and return 0; but didn't copy them. It works as expected when there is a middle name, but if there's not then it outputs this:
, t.d
My thinking was that if the middle name has no size, then it would output the last name and middle initial, but it does not. I tried outputting middleName.size() and keep getting zero, even if there is a middle name.
I appreciate any guidance, and know this is a long post, but I wanted to give as much info as I could.
I have If - else condition,
High = [18365.5, 18979.25, 19297.4, 19874.8, 20288.0, 20504.65, 20398.2]
Low = [17855.5, 18265.0, 18822.55, 18742.15, 19492.55, 20055.55, 20131.25]
Close = [18317.05, 18969.95, 18857.6, 19804.0, 20260.15, 20285.0, 20215.7]
length = len(Close) - 1
i = 0
a = 1
Trend = ["No Trend"]
Difference = ["No Trend"]
while i<length:
if Close[a] > Low[i]:
trend = "Long"
Trend.append(trend)
difference = Close[a] - Low[i]
Difference.append(difference)
elif Close[a] < High[i]:
trend = "Short"
Trend.append(trend)
difference = Close[a] - High[i]
Difference.append(difference)
i = i + 1
a = a + 1
df = pd.DataFrame(list(zip(High, Low, Close, Difference, Trend, From_date, End_date)),
columns =['High', 'Low', 'Close', 'Difference', 'Trend', 'From_date', 'End_date'])
display(df)
So i want if Close[a] > Low[i] condition is true so it will run continuously until it doesn't false, and when if condition will false so else Close[a] < High[i] condition start, so it will run continuously unitll it will not false.
I am showing you the below data frame, which will give you a clear-cut idea. 
In this Dataframe there are three columns which are High, Low, Close, and the rest of the columns are made by these three column.
So in if - condition is true so it's print "Long" continuously until It doesn't false, but when else condition start so else condition should run, and start checking this condition Close[a] < High[i]. until it doesn't false.
I'm trying my best to explain my question And Sorry, if my explanation is not good.
Let's say I have this table:
| ID | LANG | NAME | DEFAULT |
|---|---|---|---|
| 1 | ENG | Cinderella | false |
| 1 | ENG | The Ash Bride | false |
| 1 | FRE | Cendrillon | true |
| 1 | GER | Aschenputtel | false |
("Ash bride" is just fabrication that the same ID can have several names in the same language) The SQL query should return the name in the wanted language, if it doesn't exist, the default language.
So a search for the book title if your settings are in German (GER), the result should be "Aschenputtel", but if your settings are Spanish, they should return "Cendrillon".
This question brings up the same issue, but the answer suggests a double join through the name list, one for "lang='[preferred]'" and one for the default value, with a COALESCE to find the first non-null result. I am worried this would cause performance issues if the names list is long, when there cannot be a primary key (as there can be many names per language), and the question is quite old, so wonder if there is a method more along the likes of
SELECT NAME WHERE ID=1 and (LANG='SPA' OR DEFAULT=true)
and return the first non-null result of the OR-clause. Ideally, something like:
(not functional)
SELECT COALESCE(SELECT NAME WHERE ID=1 and (LANG='SPA' OR DEFAULT=true));
Anything? Or is a coalesce on a double select the only answer?
I need to loop through the sequence of variables and create a newvar conditional on other variables. The logic is the following:
loop through values i = 09 11 12 13 14 15 15b 15 16b 17 18 19
tempvar = "prefix" + "i" + "_variable"
newvar = 1 IF newvar != 1 AND tempvar == 1 AND condition1 == 2 AND condition2 == i
I tried the ifelse logic, but it does not give me the numbers I expect. It seems there are some issues with NAs and I do understand how it works.
Example of code I tried is below. It gives weird numbers, probably because there are many NA's in tempvar. Maybe I should use other approach instead of ifelse?
varnum <- c(paste0(sprintf("%02d", 9)), paste0(11:15), paste0('15b'), paste(16), paste0('16b'), paste0(17:19))
df$newvar <- NA
for (i in varnum) {
tempvar <- df[[paste0('name',sprintf("%02s", i),'_variable)]]
df$newvar <- ifelse(df$newvar != 1 & tempvar == "1" & df$condition1 == "2" & df$condition2 == i, 1, 0)
}
table(df$newvar)
In Stata I would write it like that:
global varnum "09 11 12 13 14 15 15b 16 16b 17 18 19"
gen newvar = .
foreach i in $varnum {
local tempvar = "name" + "`i'" + "_variable"
replace newvar = 1 if `newvar' != 1 & `tempvar' == "1" & condition1 == "2" & condition2 == `i'
}
tab newvar
Due to restrictions I cannot share the actual data.
Currently I am working on a loop. I tried making this with a apply function but it would not work. This loop takes ages. Also I cannot work with the ifelse function as I have nested two functions within 1 statement.
Thanks in advance
I am trying to make a code which countsdown the values in the columns to 0. When a value hits 0 it has to reset to 7 and create a new column with a value of 8. (i'm doing this for the advent of code 2021 event)
dag6 <- data.frame(var1 = 2,
var2 = 5,
var3 = 6,
var4 = 1,
var5 = 3,
var6 = 6) # Example data as loaded from file
row <- as.data.frame(8)
for (j in 1:80) {
print(j)
for (i in 1:ncol(dag6))
{if (dag6[1,i] == 0) {
dag6[1,i] <- 7
dag6 <- cbind(dag6, row)
}
else {dag6[1,i] <- dag6[1,i]-1}
}
}
I get a "syntax error" for my else-statement (commented the error) but I can't find anything wrong with my indentation.

This is my code and in this the age, marital status and gender input are not working please help me fix this I am noob and new to stack overflow ;(
#include <stdio.h>
int main(){
int age;
char ms;
char gender;
printf("\nEnter age: ");
scanf("%d",&age);
printf("\nEnter marital status: ");
scanf("%c",&ms);
printf("\nEnter gender: ");
scanf("%c",&gender);
if(ms=='M'||ms=='U'&&gender=='M'&& age>=30||ms=='U'&&gender=='F'&& age>=25)
printf("Driver is insured.");
return 0;
}
I have a condition like this, I want the first if conditional to have no reaction if you meet this condition again the second time give him a reaction, more or less like the example in the code below.
var x = -1;
if( x < 0){
console.log("is okay")
}if( x < 0 AGAIN ){
console.log("is not okay")
}
My script works as expected except that it ignores the if condition inside async def get_item - no basic errors I can see, "==" is used for if, type for comparison are both string and proof (?) that the if test is being ignored is that there is no output from the line, print("INSIDE IF"). No error messages are output.
import asyncio
AList = [['A','R','M'],
['B','W','N'],
['C','W','O'],

Asub = [] """ a yet to be nominated sub list of AList"""
List_out= [] """ output list - empty at start."""
N = 0
""" define a coroutine to simulate retrieval of an item"""
async def get_item(i):
global N
N = N + 1 """ used to count passes"""
Asub = AList[i] """nominated sub list (i range 0 to 3 for example)"""

List_out.append(value1_str)
OutLen = len(List_out)
print( "InListLen: ", num_items,"OutListLen ", OutLen)
return f'item {List_out}'

loop = asyncio.get_event_loop()
try:
"""execute the coroutine in the event loop """
loop.run_until_complete(get_items(num_items)) #num_items also works
finally:
loop.close()
Output from the above is more or less as expected - but without any evidence of the if condition being processed.
Outputs - with no change to 'W'
There seems to be little on the issue on line, and I have seen the same error in the work of a "professional" !!
This one has beaten me - any assistance much appreciated.
I'm working in visual basic on visual studio 2019. There is a way to execute all ElseIf blocks even if the first "if" or one of the precessor were true? if is not possible with the ElseIf, there is any other command I could use? The final idea and the explanation of why I can't just do separated Ifs is because I need to give a error message if all the statements were false, and I don't know how to group them without the ElseIf command, so this is the only idea I have in mind right now to do so.
So, this is the ElseIf structure, it stops when it finds one of this statements true
If(boolean_expression 1)Then ' Executes when the boolean expression 1 is true ElseIf( boolean_expression 2)Then ' Executes when the boolean expression 2 is true ElseIf( boolean_expression 3)Then ' Executes when the boolean expression 3 is true Else ' executes when the none of the above condition is true End If
So, I want to execute every single ElseIf no matters if the predecessor was true of false. I hope you can help me resolve this, thanks!
Sorry if this is an obvious problem.
I'm trying to read strings from users and store them in an array. but I want to Ignore the if case (i.e., consider “The” and “the” as the same word)
Thanks a lot for any help!
Scanner fileScanner = new Scanner(file);
fileScanner.useDelimiter("[^A-Za-z0-9]");
ArrayList<String> words = new ArrayList<String>();
while (fileScanner.hasNext()) {
String nextWord = fileScanner.next();
if (!words.contains(nextWord) ) {
words.add(nextWord);
}
}
I am trying to change the time in each Date/Time cell so that the time is 5:00:00. So that 05/10/2021 07:00:00 becomes 05/10/2021 05:00:00.
I have tried turning the cell into plain text, splitting it by the decimal and rejoining with the appropriate time, but it breaks my other formulas even though the format looks identical. I have also tried splitting the date and time, then using '''=CONCATENATE(text(A2,"M/D/YYYY")& " " &text($B$2,"H:MM:SS"))''' - the formulas still break.
I have the following code to create a file if it does not exist, creating a variable (hi), echo the variable into the file, and then read the text as a variable. If it does exist, it simply reads the text as a variable:
if exist hiscore.txt (
for /f "delims=" %%x in (hiscore.txt) do set /a hi=%%x
) else (
set /a hi=0
echo %hi%>"hiscore.txt"
for /f "delims=" %%x in (hiscore.txt) do set /a hi=%%x
)
if I create the file manually, and type 0 into it manually, it works. If I delete the file, and then run this, it says "Missing Operand" and echos "ECHO is off" into the file. What can I change?
word1 = input()
word2 = input()
a = len(word2)
b = len(word1)
count = b
while (word2[a-1] == word1[b-1]):
count-=1
a -= 1
if count == 0:
break
else:
print('it cant be made')
b-=1
print('it can be made')
What I am trying to do is compare the last letter of word2 to the last letter of word 1 and if they are equal, - the count by 1 and move down a letter in word 2 until the count is == to 0 therefore suggesting the word can be made. if the 2 letters aren't equal it should just move onto the next letter of word1 and repeat the process. if the the count doesn't reach 0 then the word can't be made because it is the Len of the word you are trying to make.
// Create a function that takes a word and returns true if the word has two consecutive identical letters.
What am I doing wrong?
module.exports = (word) => {
for (let i = 0; i <= word.length; i++) {
for (let j = i + 1; j <= word.length; j++) {
if (word[j] == word[i]) {
return true;
}
} return false;
}
};
