C++ Reference variables

Mita SG

In c++ ,once a reference is tied with a variable it cannot be tied with another variable but when you write a code as follows ,this statement seems false-

the code is

#include<iostream.h>
void main()
{
int i = 5;
int &j= i;
int p = 10;
j = p;
cout<<endl<<i<<endl<<j;
p = 20;
cout<<endl<<i<<endl<<j;

}

Can you have any explaination to sort it out?
