C++ operator is a symbol used to perform mathematical or logical manipulations. C++ language is rich with built-in operators. This tutorial describes various operators in C++.
Arithmetic Operators

==
| Is equal to |
!=
| It is not equal to |
>

<
| Less than |
>=
| Greater than or equal to |
<=

Logical Operators
| Operator | Description |
|---|---|
&&
| The "and" operator performs a logical conjunction of two expressions. (If both expressions evaluate as True, the result is true. If either expression evaluates to False, the result is false.)
|
||
| The "or" operator performs a logical disjunction on two expressions. (if either or both expressions evaluate to True, the result is true)
|
!
| It is "not" operator that performs logical negation on an expression. |
Bitwise Operators
| Operator | Description |
|---|---|
<<
| Binary Left Shift Operator |
>>
| Binary Right Shift Operator |
~
| Binary One's Complement Operator |
&
| Binary AND Operator |
^
| Binary XOR Operator |
|
| Binary OR Operator |
Assignment Operators
| Operator | Description |
|---|---|
=
| Assign |
+=
| Increment then assign |
-=
| Decrement then assign |
*=
| Multiply then assign |
/=
| Divide then assign |
%=
| Modulus then assign |
<<=
| Left shift and assign |
>>=
| Right shift and assign |
&=
| Bitwise AND assign |
^=
| Bitwise exclusive OR and assign |
|=
| Bitwise inclusive OR and assign |
Misc Operators
| Operator | Description |
|---|---|
