WebJun 10, 2024 · c = a + b; is undefined behaviour if it overflows. On a 2's complement machine, use c = a + (unsigned)b; to do the addition as unsigned and then implicitly convert back to signed. It's the same binary operation as 2's complement signed addition, but in C is guaranteed to wrap. – Peter Cordes. Oct 8, 2024 at 21:21. WebJan 5, 2016 · In C, signed integer overflow is undefined behavior but unsigned integer overflow is not. Your compiler probably will treat the two lines above identically, but to be safe you should use the unsigned add. Save a couple of instructions.
