by Dinesh Thakur Category: Operator

When number of operators occurs in an expression the operator which is to be evaluated first is judged by applying priority of operators. The arithmetic operators available in C are

+ used for Addition

-  used for Subtraction

* used for Multiplication

/ used for Division

 

% used for Modulus operation. In other words operator used to remainder after division  

When all this is used in an expression in a C program then the operator priority is applied in the following order namely

* followed by

/ followed by

% followed by

+ and this followed by –

Example to understand the concept of priority of operators is


main()

{

int a;

a=5 + 7 – 8 * 10 / 5 % 10;

printf(“a=%d”,a);

}


The output of the above program is a=6 , This occurs as follows:


a=5 + 6 – 80 / 5 % 10 (since * is operated first)

a=5 + 6 – 16 % 10 (/ is operated)

a= 5 + 7 - 6 (% is calculated)

a= 12 - 6 (+ is operated)

a=6
