C++ Program to Subtract Two Numbers

In this post, we will learn how to subtract two numbers using the C++ Programming language.

The below program asks the user to enter two numbers, after that it performs the subtraction using the minus (-) operator and stores the result in a third variable.

Then, it prints the result on the screen using the cout statement.

So, without further ado, let’s begin this tutorial.

C++ Program to Subtract Two Numbers

// C++ Program to Subtract Two Numbers
#include <iostream>
using namespace std;

int main(){
    int num1, num2, sub;
    
    // Asking for input
    cout << "Enter the first number: ";
    cin >> num1;
    cout << "Enter the second number: ";
    cin >> num2;
    
    // Subtract two numbers
    sub = num1 - num2;
    
    // Display output
    cout << "The subtraction of two numbers = " << sub << endl;
    return 0;
}

Output

Enter the first number: 32
Enter the second number: 18
The subtraction of two numbers = 14

How Does This Program Work?

    int num1, num2, sub;

In this program, we have declared three integer data type variables named num1, num2, and sub.

    // Asking for input
    cout << "Enter the first number: ";
    cin >> num1;
    cout << "Enter the second number; ";
    cin >> num2;

The user is asked to enter two numbers. The entered numbers get stored in the num1 and num2 named variables.

    // Subtract two numbers
    sub = num1 - num2;

After that, we perform the subtraction of two numbers using the minus (-) arithmetic operator. The result gets stored in the sub named variable.

    // Display output
    cout << "The subtraction of two numbers = " << sub << endl;

Finally, the result is displayed on the screen using the cout statement.

Conclusion
