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.

Creating a structure with an array of structures

In earlier versions of carddeck.c, we represented a deck of cards with a simple array of structures. Now that we need to shuffle the deck and keep track of other information about the deck, it makes sense to make our Deck structure a combination of an array of Card structures and an array of pointers to Card structures, as well as other information about the deck.

Consider the following definition of a new Deck structure:

typedef struct {
Cardordered[ kCardsInDeck ];
Card* shuffled[ kCardsInDeck ];
int numDealt;
boolbIsShuffled;
} Deck;

The orderedmember array will contain the initialized and orderedCardstructures. Once initialized, the orderedarray elements will not be modified. Instead of moving cards around in theorderedarray, we will use another array,shuffled, which is a collection of pointers to cards in theorderedarray. We will rely on the bIsShuffledmember variable to indicate when the deck has been shuffled...
