Is there no XOR operator for booleans in golang?


Is there no XOR operator for booleans in golang?

I was trying to do something like b1^b2 but it said it wasn't defined for booleans.


Solution

  • There is not. Go does not provide a logical exclusive-OR operator (i.e. XOR over booleans) and the bitwise XOR operator applies only to integers.

    However, an exclusive-OR can be rewritten in terms of other logical operators. When re-evaluation of the expressions (X and Y) is ignored,

    X xor Y -> (X || Y) && !(X && Y)
    

    Or, more trivially as Jsor pointed out,

    X xor Y <-> X != Y
