In short, it means that it returns 1 only if exactly one bit is set to 1 out of the two bits in comparison ( Exclusive OR ). A = 5 = 0101, B = 3 = 0011. A ^ B = 0101 ^ 0011 = 0110 = 6. That was the basic stuff about XOR. grape hand sanitizer

Taking for example an unsigned 8 bit integer: a = 0b10111001. Now becomes: a = {1, 0, 1, 1, 1, 0, 0, 1} Parsing. Once you can get your equations to just booleans, then you can apply the actual bitwise operators to simple 1s and 0s.
