RE: what is importance of const. pointer in copy const...

| Copy constructor is called when the copy of an object is made. One of the case is when a function argument is passed by value. So if the signature of copy constructor will take the argument by value it will get into an infinite loop. So a reference is passed and it is made constant to remain unchanged in the copy constructor. |
