# C program to perform all arithmetic operations

Write a C program to enter two numbers and perform all arithmetic operations like addition, subtraction etc to understand how to perform basic arithmetic operations in C language.

In this program we are going to perform all basic operations like addition, subtraction, multiplication, division, modulus and finding quotient of two numbers.

**Example**

```
Input: Enter first number: 20
Enter second number: 10
Output: Sum = 30
Difference = 10
Multiply = 200
Modulus = 0
Quotient = 2
```

## C program to perform all arithmetic operations

```
#include <stdio.h>
void main()
{
int num1, num2;
int sum, diff, mul, div, mod, quo;
printf("Enter first number: ");
scanf("%d", &num1);
printf("Enter second number: ");
scanf("%d", &num2);
sum = num1 + num2;
diff = num1 - num2;
mul = num1 * num2;
mod = num1 % num2;
quo = num1 / num2;
printf("Sum = %d\n", sum);
printf("Difference = %d\n", diff);
printf("Multiply = %d\n", mul);
printf("Modulus = %d\n", mod);
printf("Quotient = %d\n", quo);
}
```

**Output**

```
Enter first number: 20
Enter second number: 10
Sum = 30
Difference = 10
Multiply = 200
Modulus = 0
Quotient = 2
```
