Summary

This final chapter is the culmination of the various aspects of C programs we’ve developed throughout this book. We started by modifying and extending dealer.c to implement a simple but complete game of Blackjack. In doing so, we introduced various considerations when reusing pre-existing source code and using pre-existing libraries – source code intentionally built to be reused.

We finished by implementing a second game, very similar structurally to Blackjack, called One-Handed Solitaire. In this implementation, we not only built upon and extended dealer.c (via what we’d done with Blackjack); we also demonstrated how to incorporate some library code we unknowingly built earlier, a rudimentary linked list library. Note that when we employed this library, we also verified it with test code to exercise all of its functions. In this manner, we could rely on the library with confidence.

The development of both of these games provides a rather thorough...
