if both the base class and derived class can have the constructors,if the derived class is to call the constructor of its own using its object,it can.but when it calls its destructor,the compiler calls the destructor of base class.thats why the virtual destructor concept is coined. but there are no virtualconstructors

Whenever In inheritance hierarchy we access the objects of derived class by using generic pointer, and now we need to destroy the object, at this point the destructor of that class is called to whom generic pointer belongs and not of objects class .
Here the object does not get completely destroyed. For this reson we require virtual destructor.
