Write a C program to input two numbers and perform all arithmetic operations. How to perform all arithmetic operation between two numbers in C programming. C program to find sum, difference, product, quotient and modulus of two given numbers.

**Example**

**Input**

First number: 10 Second number: 5

**Output**

Sum = 15 Difference = 5 Product = 50 Quotient = 2 Modulus = 0

## Required knowledge

Arithmetic operators, Data types, Basic Input/Output

In previous post I explained to find the sum of two numbers.

In this exercise, we will pedal bit more and compute results of all arithmetic operations at once.

## Program to perform all arithmetic operations

```
/**
* C program to perform all arithmetic operations
*/
#include <stdio.h>
int main()
{
int num1, num2;
int sum, sub, mult, mod;
float div;
/*
* Input two numbers from user
*/
printf("Enter any two numbers: ");
scanf("%d%d", &num1, &num2);
/*
* Perform all arithmetic operations
*/
sum = num1 + num2;
sub = num1 - num2;
mult = num1 * num2;
div = (float)num1 / num2;
mod = num1 % num2;
/*
* Print result of all arithmetic operations
*/
printf("SUM = %d\n", sum);
printf("DIFFERENCE = %d\n", sub);
printf("PRODUCT = %d\n", mult);
printf("QUOTIENT = %f\n", div);
printf("MODULUS = %d", mod);
return 0;
}
```

In statement `div = (float) num1 / num2;`

, I have typecasted `num1`

to `float`

before the divide operation, to avoid integer division.

**Note:** `\n`

is an escape sequence character used to print new lines (move to the next line).

Output

Enter any two numbers : 20 10 SUM = 30 DIFFERENCE = 10 PRODUCT = 200 QUOTIENT = 2.000000 MODULUS = 0

Happy coding ðŸ˜‰
