Using virtual destructors, you can destroy objects without
knowing their type - the correct destructor for the object
is invoked using the virtual function mechanism. Note that
destructors can also be declared as pure virtual functions
for abstract classes.

if someone will derive from your class, and if someone will
say "new Derived", where "Derived" is derived from your
class, and if someone will say delete p, where the actual
object's type is "Derived" but the pointer p's type is your
class.
