Firstly Virtual constructor is really not needed at all.
Explanation:
V-table is something which stores the addresses corrospond
to all virtual function within a class.Now every class
object contains virtual pointer points to base address of
v-table in memory which is being used to resolve the
corrosponding virtual function addresses.
This v-table construction is done when object of the class
has been created,While constructor is an initialization
process in construction of the object and so v-table is not
available during initialization process and hence virtual
constructor is not possible.
