Answer / subhashish sen

Constructor can not be virtual.becoz constuctor is an entity
which initializes the V-table(V-table stores the addresses
of all virtual member functions of a class.)So if we declare
a constructor as virtual then who will inialize V-table for
this constructor??Thats why constructor can never be virual.

Answer / john

virtual constructor is not possible.
This is because v-table is created only after the
constructor is called.
