# Add, Subtract, Multiply and Division in C Programming Language

Write a program in C Programming to perform basic arithmetic operation like addition, subtraction, multiplication and division. C Programming Language comes with arithmetic operators. Operator we will use in the C Program are:

• ‘-‘ Subtraction
• ‘*’ Multiplication
• ‘/’ Division

This operation can be performed on Integer, Float or Double Number. These are Data Types.

```/**
Write a C program to perform arithmetic Operation on two Numbers
**/
#include <stdio.h>

int main()
{
int first, second, add, subtract, multiply;
float divide;

printf("Enter two integers\n");
scanf("%d%d", &first, &second);

add        = first + second;
subtract = first - second;
multiply = first * second;
divide     = first / (float)second;   //typecasting

printf("Difference = %d\n",subtract);
printf("Multiplication = %d\n",multiply);
printf("Division = %.2f\n",divide);

return 0;
}```

Output:

```Enter Two Integers
5 4
Sum = 9
Difference = 1
Multiplication = 20
Division = 1.25```

In c language when we divide two integers we get integer result for example 5/2 evaluates to 2. As a general rule integer/integer = integer and float/integer = float or integer/float = float. So we convert denominator to float in our program, you may also write float in numerator. This explicit conversion is known as typecasting.
