OK thank you for all the feedback
it was interesting seeing this
((a && !b) || (b && !a))

Using truth tables and logic gates I came up with
(in_A||in_B) && !(in_A && in_B)

Just note that the OP didn't talk about bit-wise and (&) but bit-wise
xcor, ie an operator that doesn't have a logical equivalent.

(a ^ b) is definitely shorter than ((a && !b) || (b && !a))

However, when testing two logical variables with boolean values (i.e.
always the same non-zero value for true) i't enough to write (a != b).
