`Hey,
Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
The copy constructor or destructor is a fundamental part of C++, since it automatically makes a local copy or destroys of an object. In Java everything that we manipulate is a handle, while in C++ you can have handle-like entities and you can also pass around the objects directly. That’s what the C++ copy constructor is for: when you want to take an object and pass it in by value, thus duplicating the object. So it works fine in C++, but you should keep in mind that this scheme fails in Java, so don’t use it.
Kindly revert for any queries
Thanks.

A.3 - 10 pts It is legal to have a pure virtual destructor in a C++ class as far as that destructor has a function body. Please explain the logic behind this requirement. int fu int fu Pure virtual functions in C++ can have function body implementation. Please explain a scenario when and how this implementation is used. Then please provide a sample code to access/invoke that original function code if it was overridden by a child class
