      cout<<"\n"<<"Enter the no: ";
      cin>>n;
    }
    void show()
    {
      cout<<"\n"<<"No of new Object is: "<<n;
    }
    void operator=(abc n1)
    {
      n=n1.n;
    }
};
void main()
{
abc n1,n2;
  clrscr();
  n1.getdata();
  n2=n1;
  n2.show();
  getch();
}


 


OUTPUT
Enter the no:23
