# Operators in C++

An expression consists of variables and constants separated by Operators in C++. There are mainly 8 types of Operators in C++ are given as follows :

**1. Arithmetic Operators :** Arithmetic Operators are used to perform arithmetic operations.

**2. Relational Operators :** Relational Operators are used to compare the values of operands to produce a logical value. It is a type of bool so, a logical is either **true** or **false.**

**3. Logical Operators :** Logical Operators combine two or more relational operators or expressions and produce a logical value or results.

**Example :**

x>y && x==5 x==5 || y==7

**4. Increment and decrement operators :**Increment operator

**(++)**is used to increase the value of an integer or char variable by 1. Decrement operator

**(- -)**is used to reduce the value of an integer or char variable by 1

x = 15; x++ or ++x will produce the result x = 16 x = 15; x- – or – -x will produce the result x = 14

**5. Pointer Operators :**Pointer Operators produces address values.

**Example :**

&a ptr ptr+1 "ABC"

where

**a**is a variable and

**ptr**is a pointer.

**6. Assignment Operators :** In C++, there are three types of Assignment Operators are given as below :

**(i) Chained Operators :** A chained operator is used for instance variable at the time of declaration. It can’t used to initialize varables.

a=(b=5); or a=b=5;

**(ii) Embedded Operators :**

a=(b=10)+5; (b=10) is an assignement operator that is known as Embedded Operator, Here the value 10 is assigned to b and then the result 10+5=15 is assigned to a.

**(iii) Compound Operators :** In C++, compound operator is a combination of the assignment operator with a binary arithmetic operator.

a+=5; or a=a+5; The operator += is known as Compound Assignment Operator.

**7. Bitwise Operators :** Bitwise Operators are used to manipulate data at bit level. They are basically used for testing or shifting bits.

**Example :**

a<<4 // shift four bit position to left b>> 2 // shift two bit position to right
