How the destructor can be a virtual ?

Destructor can be virtual because whenever the object goes in out of the scope then we have to delete it explicitly i.e. we need to call the destructor explicitly so destructor should made as virtual destructor like same as virtual function.

What is mean by virtual function?

Virtual functions provide run time polymorphism as the function to be executed is decided at run-time.

But if object goes out of scope, destructor is called automatically. Then why we need to call it explicitly?

In C++ there is no automatic garbage collection.

Destructor is invisibility in your program and it's call automatically. Because every constructor program using inside destructor.

Please clarify my doubt. Class is declared as virtual then how the class contain destructor?
