What are Arithmetic Operators?
Arithmetic Operators are used to performing mathematical calculations like addition (+), subtraction (-), multiplication (*), division (/) and modulus (%).
The following table shows all the arithmetic operators supported by the C language. Assume variable A holds 10 and variable B holds 20 then
| Operator | Description | Example |
|---|---|---|
| + | Adds two operands. | A + B = 30 |
| − | Subtracts second operand from the first. | A − B = -10 |
| * | Multiplies both operands. | A * B = 200 |
| / | Divides numerator by de-numerator. | B / A = 2 |
| % | Modulus Operator and remainder of after an integer division. | B % A = 0 |
| ++ | Increment operator increases the integer value by one. | A++ = 11 |
| — | Decrement operator decreases the integer value by one. | A– = 9 |
Example 1:
#include <stdio.h>
void main()
{ int i=3,j=7,k; /* Variables Defining and Assign values */
k=i+j;
printf(“sum of two numbers is %d\n”, k);
}
Output:
sum of two numbers is 10
EXAMPLE 2:
#include <stdio.h>
int main()
{
int a=40,b=20, add,sub,mul,div,mod;
add = a+b;
sub = a–b;
mul = a*b;
div = a/b;
mod = a%b;
printf(“Addition of a, b is : %d\n”, add);
printf(“Subtraction of a, b is : %d\n”, sub);
printf(“Multiplication of a, b is : %d\n”, mul);
printf(“Division of a, b is : %d\n”, div);
printf(“Modulus of a, b is : %d\n”, mod);
}
Output:
Addition of a, b is : 60
Subtraction of a, b is : 20
Multiplication of a, b is : 800
Division of a, b is : 2
Modulus of a, b is : 0
Subtraction of a, b is : 20
Multiplication of a, b is : 800
Division of a, b is : 2
Modulus of a, b is : 0
