• Meaning: An Operator is a symbol that is used to provide new values from one or more operands. The output of most operations is a Numeric value or a Boolean.
• There are Four General Classes of Operators: Arithmetic, Relational, Logical, and Bitwise.
·
1. Arithmetic

·
The output of Relational and Logical operators is a Boolean
value.
·

highest to lowest.
