Addition of Numbers Using Functions and Arrays in C++

A very simple program that I wrote during the time I'm still working as university professor to add the sum of three numbers using functions and one dimensional array in C++. I hope you will find my work useful.  Thank you.

Program Listing

#include <iostream>

 using namespace std;

int addition(int a, int b, int c)

{

    cout << "The sum of "

      << a << "," << b <<  " and "

      <<  c << " is "

      << (a + b + c) << ".";

}

main() {

    int a[2];

    cout << "\t\t ADDITION USING FUNCTION";

    cout << "\n\n";

    cout << "Enter a Value No. 1 ";

    cin >> a[0];

    cout << "Enter a Value No. 2 ";

    cin >> a[1];

    cout << "Enter a Value No. 3 ";

    cin >> a[2];

    cout << "\n";

    addition(a[0],a[1],a[2]);

    cout << "\n\n";

    system("pause");

}
