What is the preferred IDE for C? I've been using visual studio for now but opinions would be nice! :)
vscode is pretty much the best available option unless you have bleeding edge distro and could install the latest gnome builder so it would be better option ig
spacevim is nice thing to try
(imho)

I've opened the file but now I don't know how to read and sum the numbers.
take a look at std::getline

anyone ever tried resharper c++？
bdam
hi guys
bdam
I wrote a simple program inspired by an exercise from the C book (ritchie and Kernighan)
bdam
I have a weird bug and I can't fix it
bdam
could someone take a look at the 10 lines of code and help me out pls?

How about posting the code first, nobody can help you without that
klimi
Just add semicolon
klimi
I hope my crystal ball is working ok
Ariana
Isn’t bug like unexpected behaviour?
Dima
Imagine how much of undefined behaviours you can fit into 10 lines
Dima
especially in cxx

Oh sorry, I didn't know that it's allowed to post code in the group here (wanted to send it per pm)
bdam
Give me 30 min, not at work rn

If it is, use a paste site like the one in the pinned message

Ok great, thx
bdam
#include <stdio.h>
/*for every input by the user, the boolean value of c is determined and printed out*/
main()
{
int c;
c = 1;
while((c = getchar()) != EOF) {
c = getchar() != EOF;
printf("%d\n",c);
}
}
bdam
When I compiled & ran I noticed weird behavior
Dima
wtf
bdam
for example, when the input is:
bdam
ssssssssssssss
bdam
I get in return:
bdam
1
1
1
1
1
1
1
bdam
so 14x s and 7x 1
bdam
why is it not 14x 1?
Dima
use getchar once
bdam
oh, it's tokenized?
bdam
e.g it takes every second input cause I used getchar twice?
olli
#include <stdio.h>
/*for every input by the user, the boolean value of c is determined and printed out*/
main()
{
int c;
c = 1;
while((c = getchar()) != EOF) {
c = getchar() != EOF;
printf("%d\n",c);
}
}
Remove the c = getchar() != EOF;
You don't use the result from the first getchar call
bdam
Thank you guys. and now I feel dumb again lmao

Hi, working on a small program that takes 3 numbers and returns the average. The online judge I use requests that I have 2 decimal places. Not sure what I am doing wrong here.

#include <iostream>
#include <iomanip>
int main(){
int a,b,c;
double by = 3;
std::cin>>a>>b>>c;
std::cout<<std::setprecision(2)<<(a+b+c)/by;
return 0;
}

I Googled, found out about setprecision, yet something is off and not sure what.

For 9 8 7...it returns 8 instead of 8.00

Also tried:

#include <iostream>
#include <iomanip>
int main(){
int a,b,c;
std::cin>>a>>b>>c;
std::cout<<std::setprecision(2)<<float(a+b+c)/float(3);
return 0;
}
Alignant
std::cout << std::setprecision(2) << std::fixed << (a+b+c)/by;
Alignant
Try add std::fixed

That works @Alignant TY!

Need to read more on std::fixed

Is this an ok site for reading documentation or should I be using something else?
Alignant
And you shouldn't devide ints by doubles, it's confusing.
And there's nothing to read about it. std::setprecision doesn't enforce your number to have 2 digits after the dot
Alignant

It's a great website
Anonymous
So I should declare numbers a,b,c as floats or?
Alignant
double a = 10, b = 3;
std::cout << std::setprecision(3) << a/b << std::endl;
That would print 3.33. But
double a = 10, b = 3;
std::cout << std::setprecision(3) << a/b << std::endl;
But it would just print 3. setprecision sets the max precision

You can also read about the formatting of floating-point values here

and even if you wanted to do that check, you're calling getchar twice

doesn't make any sense either

he is calling getchar() twice
Anonymous
already did that check

This problem is already solved
