Beginner c program - Getting error

euser1984

Hi,
I'm using Code::Blocks as my IDE and gcc is being used as the compiler I think.

When I try to run the below code I get a process returned 320 error. Can anyone tell me what the problem is? I'm using Kernighan & Ritchies book and am trying to apply knowledge I've learned so far.

I think it may be to do with the last line as changes to this affect whether the program will run or not (if it does run after changing value = lower + step it repeatedly throws out 20. The IDE also shows this error. Process terminated with status -1073741510 (0 minutes, 4 seconds)

Also can anyone tell me how I can add proper code formatting into posts on boards?

Thanks a mill.

#include <stdio.h>

main()
{
int value;
int lower, upper, step;

lower = 0;
upper = 300;
step = 20;

value = lower;
while (value <= upper) {
printf("%d", value);

value = value + step;
}
}

For code formatting press the # button or wrap it in CODE tags.

I don't see it, whatever is wrong. The return value is garbage because you should really have a

return 0;

at the end and main should be
int main() {..}

but I don't see any other issue.

By the way you do say "value = lower + step" in your comment (which would print 20 all the time) but the code says "value = value + step" which appears right.

Edit: I don't think anything is wrong. Code Blocks is probably just reporting what it thinks your program returned. If you return 0, it'll probably say "process returned: 0"

You are not incrementing step.

You seem to want to go through a loop but you are not looping.

Always represent your programme graphically before coding, that way you stand half a chance of getting it right.

The Loop is checking for Value which is being incremented by the value of step.
no need to increment step.

I'd try the return 0; and see if that helps

Can you let me know what you mean here?

I've got it working now. To move the value up do I not need to increase it using the step value of 20. Otherwise the value will always be the same?
