Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Manipulating a structure with an array of structures

So, a question regarding when to use direct references versus using an indirect reference may come to mind. This is a very pertinent question. Unfortunately, there is no obvious answer or one that must be strictly obeyed.

In general, however, whenever a structure is declared in a function block and its elements are accessed within that function block, direct references typically make the most sense. On the other hand, when structures are declared in one function block and then manipulated by another function block, it is typically best to use indirect references (pointers) to them in the manipulating function called.

With this in mind, we can now redefine the prototypes to the Deck manipulation operations, as follows:

voidInitializeDeck( Deck* pDeck );
voidShuffleDeck(Deck* pDeck );
Card* DealCardFromDeck( Deck* pDeck );
voidPrintDeck(Deck* pDeck );

In each case, the Deck structure is not copied...
