ULONG_MAX refers to unsigned long and not to unsigned long long. For the latter, use ULLONG_MAX (note the extra L).

You need to change the printf() calls like so:

printf("unsigned long long int: \n%llu to %llu \n\n", 0ULL, ULLONG_MAX);
printf("unsigned long long int: \n%llu to %llu \n\n", ULLONG_MAX, ULLONG_MAX);

This ensures that the arguments to printf() match the format specifiers.
