Virtual Destructor is a concept, comes into picture when one
will try to delete the base object pointer pointing to
derived class.
Base* pb = new Derived();
delete pb;
In this case if Base class destructor is not virtual then
only base class destructor will be called up for clean up.

While if we make Base class destructor as virtual then
1. Derived class destructor will be called
2. Base class destructor will be called up

Proper clean up of the objects from derived as well as base
class. Mission Accomplish
