C++ Pointers, structures and user define function in a single program

Write a C++ program having concept of Pointers and structure in a single program.

#include<iostream>
using namespace std;

struct Numbers {
    int x;
    int y;
};

int add(Numbers* nums) {
    return nums->x + nums->y;
}

int main() {
    Numbers nums;
    int sum;
    
    cout << "Please enter the First Number  : " << endl;
    cin >> nums.x;
    
    cout << "Please enter the Second Number : " << endl;
    cin >> nums.y;
    
    sum = add(&nums);
    cout << "Sum of Two Numbers " << nums.x << " and " << nums.y << " = " << sum;
    
    return 0;
}

Output

Please enter the First Number :

5

Please enter the Second Number :

10

Sum of Two Numbers 5 and 10 = 15
