C Operators Let add operator to our world

An operator is a symbol which performs certain operation on values or variables.

The operators in C can be classified as:

Arithmetic Operators

An arithmetic operator performs mathematical operations such as addition, subtraction and multiplication on numerical values (constants and variables).

Operator	Meaning of Operator
+	addition
-	subtraction
*	multiplication
/	division
%	remainder after division( modulo division)

Below program demonstrate the use of arithmetic operator :

Increment and decrement Operator

Operator	Meaning of Operator
Increment ++	increases the value by 1
Decrement --	decreases the value by 1

Below program demonstrate the use of Increment and decrement Operator :

Assignment Operators

An assignment operator is used for assigning a value to a variable. The most common assignment operator is =

Operator	Example	Same as
=	a = b	a =b
+=	a += b	a = a+b
-=	a -= b	a = a-b
*=	a *= b	a = a*b
%=	a %= b	a = a%b

Below program demonstrate the use of Assignment Operators :

Relational(or logical) Operators

A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0.

Relational operators are used in decision making and loops (We will read in next chapter).

Operator	Description	Example
==	Checks if the value of two operands is equal or not, if yes then condition becomes true.	(A == B) is not true.
!=	Checks if the value of two operands is equal or not, if values are not equal then condition becomes true.	(A != B) is true.
>	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	(A > B) is not true.
<	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	(A < B) is true.
>=	Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.	(A >= B) is 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) is true.
&&	Called Logical AND operator. If both the operands are non zero then then condition becomes true.	(A && B) is true.
||	Called Logical OR Operator. If any of the two operands is non zero then then condition becomes true.	(A || B) is 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) is false.

Below program demonstrate the use of Relational Operators :
