Answer Posted / uma sankar pradhan
constructors are invoked at the time of object creation.
The v-table for virtual function mechanism is not
intialised properly during the constructor invocation.
So constructors cannot be virtual
But,destructors can be virtual.Because the V-table is
properly initialised at the time of object creation.
So the v-table is available for the destructors.
Destructors can be made pure virtual also.But unlike other
member functions,it must be redfined outside the class.
