Answer 1

What do you mean ?
It's mathematically correct.

Xor operator (^) is commutative ( a^b will be equal to b^a) and thus
((x^y)>(y^x)) will always evaluate to be false, and even your compiler is telling you the same.

Answer 2

The ^ character is the bitwise exclusive OR operator (XOR for short), which is commutative, hence the warning that a self-comparison like that always fails.

I assume you want to compute the power instead. In that case, have a look at pow() from the standard library:
