#include <stdio.h>

int main() {
    char read = ' ';

    while ((read = getchar()) != '\n') {
        putchar(read);
    }

    return 0;
}

My input is f (followed by an enter, of course). I expect getchar() to ask for input again, but instead the program is terminated. How come? How can I fix this?
