3/15/2013 5:18:50 AM Q: Define Virtual Destructor? A: By using virtual destructors, one can destroy objects without knowing their type - the correct destructor for the object is invoked by the virtual function mechanism. Note down that destructors can also be declared such as pure virtual functions for abstract classes. if someone else will derive from your class, and if someone else will say "new Derived", where "Derived" is derived through your class, and if someone else will say delete p, where the actual object''s type is "Derived" though the pointer p''s type is your class.
