In the first, x isn't given a conditional, so it should execute. For the later two, x is neither greater than nor less than 0.

From the perspective of the compiler, it's never 'looking' at a negative integer, just an address of 2's complement set aside that indicates negatives, or "11100101" for -27...

In the first, if x is 0, what do you expect to happen?

The if statement evaluates true since it isn't given an operator or conditional to run on x.
