Answer 1

x -= 1

--x doesn't give you an error because it isn't wrong. It just doesn't do anything. It's the negative value of the negative value. --x = x => -(-5) = 5. You could use -------x as well, which will be the same as -x. But you don't do anything with that value, so the whole statement is useless

Answer 2

It's infinite while loop

Answer 3

But before that you assign greater value to the same variable.
So the decrement means nothing
