The not logical operator is denoted by !.
It reverses the bool outcome of the expression that immediately follows.
Here’s the truth table:
| a | !a |
|---|---|
| false | true |
| true | false |
For instance:
( !true ) returns false( !false ) returns true( !(10 < 11) ) returns falseNote: The keyword not can be used in the place of !.
