Why is … WebAug 21, 2014 · For example, an int is defined by the C standard to be at least 16 bits. a 32-bit CPU might process 32-bit numbers efficiently, and so an int might be stored in 32 bits (or 4 bytes) for that CPU. A different CPU might only be able to process 16 bits at a time, and so it would store the number in that format instead.

WebFeb 2, 2024 · DWORD_PTR. An unsigned long type for pointer precision. Use when casting a pointer to a long type to perform pointer arithmetic.
