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?

It depends the pointer points to the object of which class.
If the pointer points to Class A, then the method defined
in class A will be called, and if the pointer points to
class B, then the method defined in class B will be called.
