if using C++ on Linux, be sure to #define __STDC_FORMAT_MACROS before including inttypes.h.

For int64_t type:

int64_t t;printf("%" PRId64 "\n", t);

for uint64_t type:

uint64_t t;printf("%" PRIu64 "\n", t);

you can also use PRIx64 to print in hexadecimal.

These macros are defined in inttypes.h
