Operators and Expressions

Definition

" Operators are the symbols which performs some operation on operands. "

" Expreation is any valid combination of operators, constants and variables. "

Types of operators

There are two types of operators

     a) On the basis of type of operands 

              1- Unary operator
              2- Binary operator
              3- Ternary operator

     b) On the basis of type operation performed 

              1- Arithmetic operator
              2- Logical operator
              3- Relational operator
              4- Bit wise operator
              5- Assignment operator
              6- Increment and Decrements operator
              7- Shorthand operator
              8- Conditional operator

A)  On The Basis Of Type Of Number Operands

1- Unary Operator -

These are the operator which operates upon single operand.

Eg-  +5, +7, -6, -54.7, x++; y--   etc

2-Binary Operator -

These are the operator which operates upon two operands.

Eg-  5+7, 10-8, 15%3, x&&y, a||b   etc.

3- Ternary Operator -

It is the operator which operates upon three operads.It is also called Conditional Operator.

Eg- ?:  (Question mark and colon)

B)  On The Basis Of  Type Of Number Operands


1- Arithmetic Operator- 

These operator is used for the performing arithmetic operation in the Expiration.

2- Logical Operator- 

These operator is used to combine logical expiration.It works on Control Statement.

3- Relational Operator-

These operator is used to determine the relation among different operand.

4- Bitwise Operator- 

These operator is used as like gates. It works on mathematical expiration. 

5- Assignment Operator-

It is used to assignment value to a variable.

Eg-  x=5;

6- Increment and Decrement Operator- 

7- Shorthand Operator-

Is used to minimize code length.

8- Conditional Operator-

This operator is used like to select one thing from two things based upon the situation.

It is also called Ternary Operator.
