Question

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.

Answer 1

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

Answer 2

With booleans an xor is simply:

if boolA != boolB {

}

In this context not equal to performs the same function as xor: the statement can only be true if one of the booleans is true and one is false.
