strtok ignores empty fields. Edward would recommend using another solution, like strcspn and some method of reading or copying a substring:

while (condition) {

#include <stdio.h>

int main()
{
printf("%d\n", EOF);
return 0;

The same number or some numbers are being repeated? Your code works just fine when Edward tests it, but repeated numbers are expected unless you go out of your way to avoid them with something like a...
