Answer Posted / lylez00
If A is a base class, and from that, B is derived, and a
dynamically allocated object of type B is deleted via a
pointer of type A, then B's destructor will not be invoked
unless A's destructor is virtual.
A *a = new B();
delete a; // won't invoke B's destructor unless A's
destructor is virtual
