WebWhat you say the code is doing is actually how bit-wise operators are supposed to work. In your example of (8 & 1): 1000 & 0001 = 0000 because in the first value, the last bit is set to 0, while in the second value, the last bit is set to 1. 0 & 1 = 0. 0111 & 0001 = 0001 In both values, the last bit is set to 1, so the result is 1 since 1 & 1 = 1.
