Both of those can give warnings depending on architecture:
#include <stdint.h>
#include <stdio.h>
#include <inttypes.h>
int main() {
uint64_t x = 0x0123456789abcdefULL;
printf("%lu\n", x); // warns on 32-bit arch
printf("%llu\n", x); // warns on 64-bit arch
printf("%llu\n", (unsigned long long)x); // correct on both
printf("%" PRIu64 "\n", x); // correct on both
return 0;
}
