if(a!=123) // legible to anyone
if(a^123) // wtf
Enter fullscreen mode Exit fullscreen mode

I don't believe this code actually improves anything, like many other snippets presented here. It sacrifices one keyboard hit for legibility.

While I might be dumb for not knowing the trick, the difficulty is to make the code better understandable, not vice versa.

Yeah, the XOR operator isn't doing an equivalence check, at least not in the way the OP is presenting. It's just not a relevant tool to use, I don't think.
