    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 !=3D =
b).
