WebThe typical size is for 32-bit architectures like the Intel i386. Some 64-bit machines might have 64-bit ints and longs, and some prehistoric computers had 16-bit ints. Particularly … WebJun 8, 2024 · An unsigned int is also 16-bits, but from 0-65535 since it’s unsigned. The fact that an int uses a fixed number of bytes (such as 4) is a compiler/CPU efficiency and limitation, designed to make common integer operations fast and efficient.

The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with. This allows great flexibility: for example, all types can be 64-bit.
