grue

Implement the Grue class as shown in the class hierarchy diagram. Place this code in the npc.h and npc.cpp files. Remember that as the Grue class inherits from NPC, it will need to implement the virtual encounter method. Grue's should have a max health of 1000000. When a Grue encounters a player, that player should be immediately killed. When a Grue encounters a player, print a message stating that the player "has been eaten by a Grue".

platypus

Implement the Platypus class as shown in the class hierarchy diagram. Place this code in the npc.h and npc.cpp files. Platypodes (platypuses? platypi?) should have a max health of 10. When a Platypus encounters a player, that player should be healed. When a Platypus encounters a player, print a message stating that the player has been "cuddled".

game

Modify the game.cpp so that there is a single vector called creatures which can store both Grues and Platypodes. Add at least one Grue and one Platypus to this vector.

encounter

Have the player encounter all the creatures in the creatures vector.
