Answer Posted / subhashish sen
Constructor can not be virtual...The main reason is when we
have a virtual function in a class the VTABLE for that
function will be created..which contains the address of the
virtual function...means for each class which contains a
virtual function a VTABLE will be created and constructor is
an entity which initializes this VTABLE.So if you declare
constructor as virtual who will initialize VTABLE for it.
Destructors can be virtual because virtual destructor
ensures proper calling order of all destructors in a class
hierarchy.
If you need further clarification reply me....
