Hi,

Can there be any use of "Pure Virtual Destructor"?
If yes, then in what scenario do we use it?

Thanks in advance.

Warm Regards.

You can, but I see no reason to have one - except perhaps for one
bizarre situation where the destructor is the main theme of the class.
Keeping it virtual and empty is sufficient.

Sure.

For deleting object through their abstract interface?

It might be a valid solution for home-made synchronous garbage
collectors or other on-demand mechanisms for deleting groups of objects,
for example.

You can. The purpose is to mark a class as abstract that has no other pure
virtual functions.

Note that you can still provide an implementation even if the destructor
is pure virtual.

Yes.

I have trouble imagining one.
