Question

Implement a two player game. You are given a main, and a game source file and the creature class definition file.

1. Create the enumerator type in the creature.h file

2. Allocate the creature (derived) objects in the RequestCreatureType() function (game.cpp) by using the new operator.

3. Implement all the methods for the Creature class and its derived classes.

4. Make the game compile and run successfully.
