Example: Sum of Two Numbers using Class with User Input in C++

// Sum of Two Numbers using Class with User Input
#include <iostream>
using namespace std;

// Define a class named 'InteractiveAdder'
class InteractiveAdder {
private:
    int num1;
    int num2;

public:
    // Method to get numbers from the user
    void getNumbersFromUser() {
        cout << "Enter first number: ";
        cin >> num1;
        cout << "Enter second number: ";
        cin >> num2;
    }

    // Method to calculate the sum
    int calculateSum() {
        return num1 + num2;
    }

    // Method to display the sum
    void displaySum() {
        cout << "The sum of " << num1 << " and " << num2 << " is: " << calculateSum() << endl;
    }
};

int main() {
    // Step 1: Create an object of the 'InteractiveAdder' class
    InteractiveAdder userAdder;

    // Step 2: Call the 'getNumbersFromUser' method to prompt for input
    userAdder.getNumbersFromUser();

    // Step 3: Call the 'displaySum' method to show the result
    userAdder.displaySum();

    return 0;
