Operators in C language
are the symbol that act upon data .They represent a particular operation to be performed on the data. Operator can be classified in the following categories:
•Arithmetic Operators:
The arithmetic operator perform arithmetic operation on any built in data type.
Operator Function
+ Addition
- Subtraction
× Multiplication
/ Division
^ Exponentiation
% Modulus(Remainder)
•Special Arithmetic Operation:
++ : increment
-- : decrement
X++ or : is equivalent to X=X+1
++X
Similarly
X-- or --X : is equivalent to X=X-1
•Relational Operators
These operators are used to compare two values on the basis of a certain condition .
Operator Function
< Less than
<= Less than equal to
> Greater than
>= Greater than equal to
!= Not equal to
== Equal to
•Logical Operators:
These operators are used to perform logical operation.
Operator Function
&& AND
|| OR
! NOT
• Assigning Operators:
These operators are used to assign values to variable.
Operator Function
= Assign a value
+= Add the value and assign it
to the left.
-= Subtract the value and assign
it to left side.
*= Multiple the values and assig-
n it to left side.
/= Divide the values and assign it
to left side.
%= Find the reminder and assign
it to the left side.
•Ternary Operators:
These operators are very powerful operators in C language. In some cases ,it equivalent to the "if" - els statement.
Operators"?" and ":"
syntax=> expression =exp 1? exp 2: exp 3;
Example:
a=50;
b=a>100?25:35;
Here the value of b will be 35 because a is less than 100 and the condition is false .
