The only problem left is that if you have enabled warnings about signed-unsigned comparison (to detect these kind of mistakes) it would still warn. Webwhen would you use a negative comparison in programming. In those cases, it's clearer to talk about "negation / opposite of the outcome being true" vs "outcome not being true"; however the point is that it would be even clearer to introduce an 'empty' step, or invert the meaning of the variable names. Most switch statements end each case with. The XOR of x and y will have the sign bit as 1 if they have opposite sign.

However it looks much more familiar when written as such: Leaving the else branch empty here would cause a value to be undefined - in most cases, not what we want to be a valid case when programming functionality. The issue about avoiding negatives deserves some more attention though: Typically, whenever you need to use a boolean value, you need some blocks of code to operate when it's set, and some other blocks to operate when it's not set.
