The using of pointers between two variables (Swaping)

This code let you see the using of the pointers for the integer a, b and how we swap these pointers

Code:

#include<iostream.h>
void main()
{
    int a=5,b=4;

   int &refa=a,&refb=b;
   int temp;
    cout<<&refa<<&refb<<endl;
   temp=refa;
   refa=refb;
   refb=temp;
 

    cout<<&refa<<&refb<<endl; 
}
