#include <iostream>
using namespace std;

int main() {
    int num1, num2, sum;

    cout << "Enter first number: ";
    cin >> num1;

    cout << "Enter second number: ";
    cin >> num2;

    sum = num1 + num2;

    cout << "Sum: " << sum;

    return 0;
}

This C++ code prompts the user to enter two integers, reads those values, calculates their sum, and finally displays the result.
