    Key combo

    Code:
    int main(int argc, char *argv[]) {
    int test;
    test = 0;
    while (1) {
    	test++;
    }
    test--;
    printf("%d",test);
    return 0;
    This small test program runs until the end of time (console linux ). Now my question is.

    How do you make the while lus end by pressing a key or key combo?

    Along the lines of: while("A" is not pressed) ....

    You can use kbhit(). This will loop until a key is pressed:
    Code:
    while(!kbhit()) {
        puts("You haven't pressed a key yet . . .");
    }
    If you want to exit the loop only when a key is pressed, try this:
    Code:
    for(;;) {
        if(kbhit()) {
            if(getch() == 'A') break;
        }
    
        test++;
    }
    If you don't mind waiting, use scanf() or getchar().
