Logical Operators

Logical Operators can be used for combining two logical expressions or logical values. Following are the three logical operators:

Operator	Operation
&&	AND
\|\|	OR
!	NOT

Note
An operand refers to a value or expression that is used as an input for an operator in a statement or expression. For-example in the expression 1 + 2, the values 1 and 2 are operands. In the case of logical operators, an operand is always a boolean expression or value.

The AND (&&) operator takes two operands and returns true only if both the operands are true. It is demonstrated by the following code:

main.cs

Instead of directly using the true and false literals (values), we commonly use expressions:

main.cs

The OR (||) operator returns true if any one of the operands is true:

main.cs

Following is an example which uses the OR (||) operator:

main.cs

The NOT (!) operator simply negates (inverts) the logical expression or logical value. So if an expression returns true, it changes it into false.

main.cs
