Operators in C

An operator is a symbol that specifies the operation or activity to be performed. For example + means add , - means subtract  and  * means multiply.

a + b /*Here a and b are operands and + is an operator */
a++   /*Here a is operand and ++ is the operator */

We can classify operator on 

  1. Number of operands an operator has.
  2. The type of operation being performed.

1. Operators classification based on number of operands

Based on number of operand, operators can be classified into four major category.Operators classification based on operands

Unary Operators: An operator which act on only one operand to produce result is called unary operator. For example +x, ++a, !b

Binary Operators: An operator which act on two operands to produce result is called binary operator. For example a+b, a%b, a>>1

Ternary Operators: An operator which act on three operands to produce result is called ternary operator. For example x?y:x.

2. Operators classification based on type of operation

Classifying based on type of operation being performed gives a clear picture of all operators.

 

we will discuss each operator in detail with example in next topics.
