Operators in C

Operators in C programming Language

An operator is a symbol that instructs C to perform some operation, or action, on one or more operands.  Operator which requires 1 operand (something where operator acts on) is called unary operator, operators which requires 2 operators are called binary operators and the operator which requires 3 operands is ternary operator.

For example: 

There are different types of operators in C

Arithmetic Operators

Relational Operators
Equality operators

Logical Operators

Assignment Operators etc.

• Arithmetic Operators:

An arithmetic is used for basic operations such as addition, subtraction and multiplication ( mathematical and arithmetic calculations). C has 5 arithmetic operators.

Operator	Meaning of Operator	Example
+	addition	A+B
-	subtraction	A-B
*	multiplication	A*B
/	division	A/B
%	remainder	A%B

• Relational Operators:

A relational operator checks the relationship between two different  operands. C provides 4 relational operators. It gives the result in terms of  true ( 1 ) and false ( 0 ).

Operator	Meaning of Operator	Example
<	Less than	A<B
>	Greater than	A>B
<=	Less than equal to	A<=B
>=	Greater that equal to	A>=B

• Equality operators 

The operator which is used to compare two operands to check their equality is known as equality operators.

Operator	Meaning of Operator	Example
==	Equal to	A==B
!=	Not equal to	A!=B

• Logical Operators 

The operator which logically connect the logical expression is called logical operator. It gives the result in binary value ( true = 1 and false = 0)

Operator	Meaning of Operator	Example
&&(AND)	True only if all operands are true.	A&&B
.. (OR)	True only if either one operand is true.	A..B
! (NOT)	True only if the operand is false.	!A

• Assignment Operators

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

Operator	Meaning of Operator	Example
+=	Add and assign	A+=B (A=A+B)
-=	Subtract and assign	A-=B (A=A-B)
*=	Multiply and assign	A*=B (A=A*B)
/=	Divide and assign	A/=B (A=A/B)
%=	Remainder and assign	A%=B (A=A%B)
