Operators in C

In this section we will learn about various Operators. An operator is a symbol which performs for specific mathematical or logical operation. For an example, plus (+) operator is used for addition and minus (-) operator is used for subtraction.

Here we will talk about the following operators

• Arithmetic Operators
• Increment / Decrement Operators
• Assignment Operators
• Relational Operators
• Logical Operators

Arithmetic Operators

Arithmetic Operators are used to perform mathematical operation like addition, subtraction, division and multiplication. Following table shows the arithmetic operators with example. Let, X = 5 and Y = 2

Operator	Operation	Description	Example
+	Addition	Adds two operands	X + Y = 7
-	Subtraction	Subtracts second operand from the first	X - Y = 3
*	Multiplication	Multiplies both operands.	X * Y = 10
/	Division	Divides numerator by denominator.	X / Y = 2.5
%	Modulus	Gives remainder value after divides the first operands by second operands	X % Y = 1

Increment / Decrement Operators

Increment (++) Operator increases value by one and Decrement (--) Operator decreases value by one. Following table shows Increment / Decrement operators with example. Let, X = 5 and Y = 2

Operator	Operation	Description	Example
++	Increment	increases value by one	X++ is equal to 6
--	Decrement	decreases value by one	Y-- is equal to 1

Assignment Operator

Assignment Operators are used to assign value into variables. Following table shows the Assignment operators with example.

Operator	Description	Example	Same As
=	Assigns values from right side operands to left side operand	X = Y	X = Y
+=	Add and assignment operator	X += Y	X = X + Y
-=	Subtract and assignment operator	X -= Y	X = X - Y
*=	Multiply and assignment operator	X *= Y	X = X * Y
/=	Divide and assignment operator	X /= Y	X = X / Y
%=	Modulus and assignment operator	X %= Y	X = X % Y

Relational Operators

Relational Operators are used to compare between two operands. Following table shows the Relational operators with example. Let, X = 5 and Y = 2

Operator	Description	Example	True/False
==	Is Equal to	X == Y.	(5 == 2) False
!=	Is Not Equal to	X != Y	(5 != 2) True
>	Greater than	X > Y	(5 > 2) True
<	Less than	X < Y	(5 < 2) False
>=	Greater than or Equal to	X >= Y	(5 >= 2) True
<=	Less than or Equal to	X <= Y	(5 <= 2) False

Logical Operators

Logical Operators are used in decision making. Following table shows the Logical operators with example. let X = True and Y = False

Operator	Description	Example	True/False
&&	Checks both operands are True	(X && Y)	False
||	At least one of the Operands is True	(X || Y)	True
!	It checks the reverse condition is true or not	!(X)	False
