Arithmetic Operators

C programming language supports almost common arithmetic operator such as +,-,* and modulus operator %. Modulus operator (%) returns the remainder of integer division calculation. The operators have precedence rules which are the same rule in math.

Here is a C program demonstrate arithmetic operators:

01.#include <stdio.h>

02./* a program demonstrates C arithmetic operators */

03.void main(){

04.int x = 10, y = 20;

05. 

06.printf("x = %d\n",x);

07.printf("y = %d\n",y);

08./* demonstrate = operator + */

09.y = y + x;

10.printf("y = y + x; y = %d\n",y);

11. 

12./* demonstrate - operator */

13.y = y - 2;

14.printf("y = y - 2; y = %d\n",y);

15./* demonstrate * operator */

16.y = y * 5;

17.printf("y = y * 5; y = %d\n",y);

18. 

19./* demonstrate / operator */

20.y = y / 5;

21.printf("y = y / 5; y = %d\n",y);

22. 

23./* demonstrate modulus operator % */

24.int remainder = 0;

25.remainder = y %3;

26. 

27.printf("remainder = y %% 3; remainder = %d\n",remainder);

28. 

29./* keep console screen until a key stroke */

30.char key;

31.scanf(&key);

32.}

And here is the output

x = 10
y = 20
y = y + x; y = 30
y = y - 2; y = 28
y = y * 5; y = 140
y = y / 5; y = 28
remainder = y % 3; remainder = 1
