Simple way:

public int FindDepthOfTree(RBNode n)
{
if (n == null) return 0;
return Math.Max(FindDepthOfTree(n.LeftNode),
FindDepthOfTree(n.RightNode)) + 1;
}

They started with the brief introduction followed by few basic C++ questions on polumorphism, inheritance and then virtual functions. What is polymorphims? How you will access polymorphic functions in C? How virtual function mechanism works?
