If not, a run-time error is raised. Boolean values are treated as numbers (0 if false, 1 if true).The operator is applied to the resulting number.For the ! operator, if expression is nonzero, result is zero. If expression is zero, result is 1....

But x is not greater than y, so how is this possible? The answer is that because the logical NOT operator has higher precedence than the greater than operator, the expression ! x > y actually evaluates as (!x) > y. Since x is 5, !x evaluates to 0, and 0 > y is false, so ...
