WebJun 6, 2024 · C and C++ use 32 bit int because otherwise there is no 32 bit type available (char = 8 bit, short = 16 bit or you have no 16 bit type, int must be 32 bit or you have no 32 bit type). Swift on 64 bit devices has Int = 64 bit, but also has Int8, Int16, Int32 and Int64 so the problem that C has is avoided. – gnasher729 Jun 6, 2024 at 18:53 4 WebLimits of cstdint types Where N is one in 8, 16, 32, 64, or any other type width supported by the library.
