#include <inttypes.h>
The inttypes.h header includes definitions of, at least, the following types:
| int8_t | 8-bit signed integral type. |
| int16_t | 16-bit signed integral type. |
| int32_t | 32-bit signed integral type. |
| int64_t | 64-bit signed integral type. |
| uint8_t | 8-bit unsigned integral type. |
| uint16_t | 16-bit unsigned integral type. |
| uint32_t | 32-bit unsigned integral type. |
| uint64_t | 64-bit unsigned integral type. |
| intptr_t | Signed integral type large enough to hold any pointer. |
| uintptr_t | Unsigned integral type large enough to hold any pointer. |
