How do you format an unsigned long long int using printf?
...want to try using the inttypes.h library that gives you types such as
int32_t, int64_t, uint64_t etc.
You can then use its macros such as:
uint64_t x;
uint32_t y;
printf("x: %"PRId64", y: %"PRId32"\n", x, y);
This is "guaranteed" to not give you the same trouble as long, unsigned long long etc, ...
