In this thread we pick up innocent programs and tank the shit out of them.

#include <stdio.h>
int main () {
  int n1, n2;
  printf("First integer:");
  scanf("%d", &n1);
  printf("Second integer:");
  scanf("%d", &n2);
  printf("Sum = %d\n", n1+n2);
  return 0;
}

also, http://www.opengroup.org/onlinepubs/000095399/functions/fgets.html gives this example:
#include <stdio.h>
...
char line[LINE_MAX];
...
while (fgets(line, LINE_MAX, fp) != NULL) {
...
}
