Creating and Using References for integer

  

#include <iostream>



int main()

{

   using namespace std;

   int  intOne;

   int &rSomeRef = intOne;



   intOne = 5;

   cout << "intOne: " << intOne << endl;

   cout << "rSomeRef: " << rSomeRef << endl;



   rSomeRef = 7;

   cout << "intOne: " << intOne << endl;

   cout << "rSomeRef: " << rSomeRef << endl;



   return 0;
