C++ Operators

C++ Operators

An operator may be a symbol that tells the compiler to perform specific mathematical or logical manipulations

C++ divides the operators into the subsequent groups:

• Arithmetic Operators
• Relational Operators
• Logical Operators
• Bitwise Operators

Arithmetic Operators

There are following arithmetic operators supported by C++ language −

Let Say, A = 10 and B = 20, then -

Operators	Description	Example	Output
+	Add Two Operands	A + B	30
-	Substract Two Operands	A - B	-10
*	Multiplies Two Operands	A * B	200
/	Divides Two Operands	B / A	2
%	Modulus Two Operands	B % A	0
++	Increase Value By One	A++	11
--	Increase Value By One	A--	9

Relational Operators

There are following relational operators supported by C++ language −

Let Say, A = 10 and B = 20, then -

Operators	Description	Example	Output
==	Checks if the values of two operands are equal or not.if the value are same then condition becomes true.	A == B	Not True
!=	Checks if the values of two operands are equal or not.if the value are not same then condition becomes true	A == B	True
>	Checks if the worth of left operand is bigger than the worth of right operand, if yes then condition becomes true.	A > B	Not True
<	Checks if the worth of left operand is a smaller amount than the worth of right operand, if yes then condition becomes true	A < B	True
>=	Checks if the worth of left operand is bigger than or adequate to the worth of right operand, if yes then condition becomes true.	A >= B	Not True
<=	Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.	A <= B	True

Logical Operators

There are following logical operators supported by C++ language.

Let Say, A = 1 and B = 0, then -

Operators	Description	Example	Output
&&	Called Logical AND operator. If both the operands are non-zero, then condition becomes true.	A && B	False
||	Called Logical OR Operator. If any of the two operands is non-zero, then condition becomes true.	A || B	True
!	Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true, then Logical NOT operator will make false.	!(A && B)	True

Bitwise Operators

Bitwise operator works on bits and perform bit-by-bit operation.

The truth tables for &, |, and ^ are as follows −

p	q	p & q	p | q	p ^ q
0	0	0	0	0
0	1	0	1	1
1	1	1	1	0
1	0	0	1	1
