Arithmetic Operators in C Language

 Arithmetic Operators

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

Flowing Arithmetic Operator according to their priority orders.--

Here top three has same and higher priority order as compare to bottom two. If top three or bottom two operator i.e. * / % or + - are in one instruction/line so we can solve it from associativity rule i.e. Left to Right order.

FOR EXAMPLE :-

#include <stdio.h>

int main ()

{

int a=9, b=4, c;

c= a+b;

printf("a+b = %d \n", c);

c= a-b;

printf("a-b = %d \n", c);

c= a*b;

printf("a*b = %d \n", c);

c= a/b;

printf("a/b = %d \n", c);

c= a%b;

printf("Reminder when a divided by b = %d \n", c);

return 0;

}

Output 

a+b =13

a-b =5

a*b =36

a/b =2

Reminder when divided by b=1

The operators +,- and * computes addition, subtraction and multiplication respectively as you might have expected. 

In normal calculation, 9/4= 2.25. However, the output is 2 in the program.It is because both variables a and b are integer. Hence, the output is also an integer.

The modulo operator % computes the remainder. When a=9 is divided by b=4, the remainder is 1. The % operator can only be used with integers. Please like share...
