The logical operators are:
- && Logical AND (and)
- || Logical OR (or)
- Considerations

- Two subexpressions joined by a logical operator form a logical expression.
- Logical expressions resolve to a Boolean value: 1/0 or TRUE/FALSE.
- Logical expressions can be grouped using parentheses: ()
- Parentheses are used in pairs. For each left parenthesis, there must be a right parenthesis. For example:
- ((<expression1> && <expression2>) || <expression3>) && (<expression_4)
