Answer / sandip
To avoid local copy of object reference (&) is used in copy
constructor.
Moreover if the & is ommited then copy constructor goes in
infinite loop.
eg. if class name is Sample.
Copy constructor without &
Sample :: Sample (Sample s)
{
//Code goes here
}
and we create object as follows. ;
Sample s;
Sample s1(s);
In this scenario program will go in infinite loop.

constuctor one more time and another copy will be created
there and so on...
