Thread: Loop isn't printing

I'm new to C and was trying to teach myself some simple things first. I don't particularly know why this code is not performing like I would think it would:

Code:

int main() {
    int ch;
    int i4 = 0;
    while ((ch = getchar()) != '\n' && ch != EOF) {
        printf("%i", i4);
        i4++;
    }
    return(0);
}

I would think that this would be an infinite loop that would print integers increasing by 1 and the loop wouldn't stop until I pressed enter.

The loop just exits when I hit enter with no printing at all to the screen. What's wrong here?

I see what you're saying. What would be a way to check for input from the user while still looping and printing those numbers?

Code:

#include <stdio.h>
#include <conio.h>

int infiniteloop(int index);

int main() {
    infiniteloop(0);
}

int infiniteloop(int index) {
    int ch;
    int i4 = index;
    while (!_kbhit()) {
        i4++;
        printf("%d\n", i4);
    }
    
    if((ch = _getch()) != 13) {
        infiniteloop(i4);
    }
    
    return(0);
}

This works now, but I have a dependency on Windows. I'm using Visual Studio 2005 on XP Pro and want to write code that's not OS dependent.

I want to be able to loop numbers, print them to the screen, and stop the loop when I press enter. Is there a way to do it without using _kbhit?

This just seems like something that somebody must have done before but I'm not coming up with anything specifically like this.
