/*
Exercise 1-6. Verify that the expression getchar() != EOF is 0 or 1.
===
Each character typed returned a 1, until I typed Ctrl+d, to signify the end of
input, which yielded a 0. Therefor, getchar()!=EOF is 1 with all characters and
0 a the end of input/file. Thus, it always equals 0 or 1.
*/
#include <stdio.h>
int main () {
int c;
while ((c=getchar())!=EOF) {
printf("%d ", c!=EOF); /* while input */
} printf("%d ", c!=EOF); /* on input end */
