WebJan 25, 2013 · Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits). On the other hand, int is guaranteed to be present in every implementation of C, where int8_t and int32_t are not.
