When no negative numbers are required, unsigned … WebPerforming arithmetic on unsigned fixed-width integer types can lead to subtle bugs. For example: Let uint16_t = unsigned short and let int be 32-bit. Then uint16_t x=0xFFFF, y=0xFFFF, z=x*y; would have x and y promoted to int, and x * y would overflow int – hence undefined behavior. Let uint32_t = unsigned char and let int be 33-bit.
