﻿ C : Add, subtraction, multiplication of 2 numbers

# C Exercises: Perform addition, subtraction, multiplication and  division of two numbers

## C Input Output statement: Exercise-9 with Solution

Write a C program to perform addition, subtraction, multiplication and division of two numbers.

Pictorial Presentation:

Sample Solution:

C Code:

``````#include <stdio.h>    // Include the standard input/output header file.

int main()
{
int num1, num2;   // Declare two integer variables 'num1' and 'num2'.
int sum, sub, mult, mod;   // Declare variables to store the results of arithmetic operations.
float div;   // Declare a float variable 'div' to store the result of division.

/*
* Read two numbers from user separated by comma
*/
printf("Input any two numbers separated by comma : ");   // Prompt the user to input two numbers separated by a comma.
scanf("%d,%d", &num1, &num2);   // Read and store the user's input in 'num1' and 'num2'.

/*
* Performs all arithmetic operations
*/
sum = num1 + num2;   // Calculate the sum of 'num1' and 'num2'.
sub = num1 - num2;   // Calculate the difference between 'num1' and 'num2'.
mult = num1 * num2;  // Calculate the product of 'num1' and 'num2'.
div = (float)num1 / num2;   // Calculate the division of 'num1' by 'num2' and cast the result to a float.
mod = num1 % num2;   // Calculate the modulus of 'num1' and 'num2'.

/*
* Prints the result of all arithmetic operations
*/
printf("The sum of the given numbers : %d\n", sum);   // Print the sum.
printf("The difference of the given numbers : %d\n", sub);   // Print the difference.
printf("The product of the given numbers : %d\n", mult);   // Print the product.
printf("The quotient of the given numbers : %f\n", div);   // Print the quotient.
printf("MODULUS = %d\n", mod);   // Print the modulus.

return 0;   // Return 0 to indicate successful execution of the program.
}
```
```

Sample Output:

```Input any two numbers separated by comma : 10,5
The sum of the given numbers : 15
The difference of the given numbers : 5
The product of the given numbers : 50
The quotient of the given numbers : 2.000000
MODULUS = 0
```
