Answer Posted / subhashish sen
Constructor can't be virtual,becoz constructor is an entity
which initializes V-table(V-table contains addrress of all
the virtual functions of class).So if we declare constructor
as virtual the who will intialize V-table for this constructor.
Destructor can not be overloaded simply becoz we cant
provide argument to a destructor and also its going to
release the memory when an object goes out of scope.
