LOGICAL OPERATOR
-
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.
- Use parentheses--()--to group expressions logically and to join multiple expressions.
- Parentheses are used in pairs; each open parenthesis "(" requires a closing parenthesis ")".
- For example:
- ((<expression1> && <expression2>) || (<expression3> && <expression_4>))
