# OPERATORS AND EXPRESSIONS IN ‘C’

Operators form expressions by joining individual constants, variables, array elements as discussed in previous lesson. C includes a large number of operators which fall into different categories. In this lesson we will see how arithmetic operators, unary operators, relational and logical operators, assignment operators and the conditional operators are used to form expressions.

The data items on which operators act upon are called operands. Some operators require two operands while others require only one operand. Most operators allow the individual operands to be expressions. A few operators permit only single variable as operand.
