Counting Program

Source Code

#include <stdio.h>

int main() {

double nc;

for(nc=0;getchar()!=EOF;++nc)

;

printf("%.0f\n",nc);

}

if the input contains no characters, the while or for test fails on the very first call to get char, and the program produces zero. while and for is that they test at the top of the loop, before proceeding with the body. If there nothing to do, nothing is done. Even if that means never going through the loop body.
