Summary
In this chapter, we have covered pointers and discussed that they are variables that hold a memory address to a specific type of object. The full significance of this will begin to reveal itself as this book progresses and the power of pointers is revealed. We also used pointers in order to create a huge horde of zombies that can be accessed using a pointer, which it turns out is also the same thing as the first element of an array.
We learned about the STL, and in particular the map class. We implemented a class that will store all our textures, as well as provide access to them.

In the next chapter, we will make two more classes: one for ammo and health pickups and one for bullets that the player can shoot. After we have done that, we will...
