Return value

On success, getchar returns the character read, after converting it to an int without sign extension. On end-of-file or error, it returns EOF.

Example

#include <stdio.h>

int main(void)
{
   int c;

   /* Note that getchar reads from stdin and  is line buffered; */
   /* this means it will not return until you press  <ENTER> */
   while ((c = getchar 0)  1= '\n')
      printf("%c", c);
return
