Implementing Game State
The logic presented in Figure 4-7 is implemented in the class CoinsController . To help you
understand how the class CoinsController creates the Coin Sorter game, let's take a look at the
header file. There you can get an overview of the class, shown in Listing 4-7.
Listing 4-7. CoinsController.h
