Logical Operators

• Logical operators are used to compare values using truth table.
• It is answerable by TRUE (1) or FALSE (0).

The result is always the opposite of its value.

AND Operator (&&)

[pic 5]

The result is always FALSE if at least one of its value is FALSE.

OR Operator (||)

[pic 6]

The result is always TRUE if at least one of its value is TRUE.
