We are nearly there. This short chapter will demonstrate how we can easily manipulate files stored on the hard drive using the C++ standard library, and we will also add sound effects. Of course, we know how to add sound effects, but we will discuss exactly where in the code the calls to play
will go. We will also tie up a few loose-ends to make the game complete.
In this chapter we will learn the following topics:
Saving and loading the high score
Adding sound effects
Allow the player to level up
Create never-ending multiple waves
