@lore Zallen {0,1}.
Seemingly the negation of X and 1. Negation of X being the bit flip of the binary number. So it's going to be swapping to truth value and adding a 1 to it. It could return the same value or probably cause a compiler error. The bool is not bitwise but the operation occurs outside the bool.
It's not comfortable code to look at.
@AmpBenzScientist it's not really adding a 1 because that's an AND, not an OR. and in C/C++, bool is just an integer type. it's considered true if nonzero.
@AmpBenzScientist in Java/C# it would probably cause a syntax error, but you typically don't see much bitmasking code of this sort in those languages. i could have mentioned that this is C99 code (earlier revisions lack a "bool" type) i guess.
