Introduction

The following table lists C's arithmetic operators.

Operator Action
- Subtraction, also unary minus
+ Addition
* Multiplication
/ Division
% Modulus
-- Decrement
++ Increment

When you apply / to an integer or character, any remainder will be truncated. For example, 5/2 will equal 2 in integer division.

The modulus operator % yields the remainder of an integer division. However, you cannot use it on floating-point types.

The following code fragment illustrates %:

Demo Code

#include <stdio.h>

int main(void)
{

   int x, y;//from  ww w.jav  a2s.c o  m

   x = 5;
   y = 2;

   printf("%d \n", x / y);  /* will display 2 */
   printf("%d \n", x%y);  /* will display 1, the remainder of
                          the integer division */

   x = 1;
   y = 2;

   printf("%d %d \n", x / y, x%y); /* will display 0 1 */


   return 0;
}

Result

The unary minus multiplies its operand by -1. That is, any number preceded by a minus sign switches its sign.
