Building the Thomas and Bob classes
Now, we get to use inheritance for real. We will build a class for Thomas and a class for Bob. They will both inherit from the PlayableCharacter class we just coded. They will then have all the functionality of the PlayableCharacter class, including direct access to its protected variables. We will also add the definition for the pure virtual function, handleInput. You will notice that the handleInput functions for Thomas and Bob will be different.
Coding Thomas.h
Right-click Header Files in the Solution Explorer and select Add | New Item.... In the Add New Item window, highlight (by left-clicking) Header File (.h) and then, in the Name field, type Thomas.h. Finally, click the Add button. We are now ready to code the header file for the Thomas class.
Add the following code to the Thomas.h class:
#pragma once
#include "PlayableCharacter.h"
class Thomas : public PlayableCharacter
{
public:
    // A constructor...
