    Little Confused..?

    Ok i've been reading a book called "C for Dummies" which has alot of padding. It show you some basic things like printf.. and how to compile.

    When you run these "programs" in the book they run though cmd, but the program doesn't complete (or it does but you don't see it), you see it closes as soon as the program is finish. What do I need to add to the code you keep it open untill someone exits.

    Thanks.

    Hi, welcome to the forums!

    You can use the getchar() function at the end of your program. More details are available in this FAQ entry.
    How do I get my program to wait for a keypress?

    Make sure you have read this before posting code.

    welcome!

    im a bit of a newbie too! you can of course put while(1) after the code is executed in the int main() function, which basically means while forever (or user closes program) so eg:

    Code:
    #include <stdio.h>
    
    int main()
    {
       printf("Hello World\n"); /* a trivial example */
    
       while(1) /* while forever */
       {
          /* do nothing */
       }
       
       return(0);
    }
    hope this helps!

    I would avoid using this method - it effectively means that you have to force your program to stop and affects portability (eg *nix based operating systems dont really like having processes killed). I would stick to the getchar method

    In what way?
    If you understand what you're doing, you're not learning anything.

    Mine cackles gleefully when it gets a chance to kill a process. But maybe that's just mine...

    Why do I imagine you have the Doom process management utility Quzah?
    Demonographic rhinology is not the only possible outcome, but why take the chance
