Assuming you've access to the source code, then this is possible (at least in cygwin):

#include <stdio.h>
#include <unistd.h>

int
main(void)
{
  int n;
  printf ("Enter value:");
  scanf("%d", &n);
  if (isatty(STDIN_FILENO)==0)
    printf("%d\n", n);
  printf("Value was %d\n", n);
  return(0);
}
