WebProper manual logical XOR implementation depends on how closely you want to mimic the general behavior of other logical operators ( and &&) with your XOR. There are two important things about these operators: 1) they guarantee short-circuit evaluation, 2) they introduce a sequence point, 3) they evaluate their operands only once.
WebJan 1, 2000 · The uppermost bit of the XOR result is always zero and promptly shifted out of the remainder Since we already have the information in the uppermost bit and we don't need it for the XOR, the polynomial can also be stored in an 8-, 16-, or 32-bit register. We can simply discard the most significant bit. WebMar 12, 2024 · In C++, though we have logical OR ( ) and logical AND (&&), we do not have logical XOR. Using the existing operators, we can mimic the functionality of logical XOR. …
