suppose A is a base class and B is the derved class. Both
have a method foo which is defined as a virtual method in
the base class. You have a pointer of classs B and you
typecast it to A. Now when you call pointer->foo, which
method gets called?
The next part of the question is, how does the compiler
know which method to call?
