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 an array of structures

Now that we have a deck of cards, what are some operations that we might need to perform on it? Two operations immediately come to mind—first, initializing the deck to the proper suit and face values, and second, printing out the deck of cards.

Let's add the following two function prototypes to the program, as follows:

void InitializeDeck( Card* pDeck );
void PrintDeck(Card* pDeck );

In each function, the function takes a pointer to a Card structure, which for now is an array of Card. These will operate on the entire deck, so no other parameters are needed for these functions.

To initialize our deck of cards, we will loop through the array, setting the structure member values. Before we show that, however, consider the patterns of repetition in an ordered card deck. Each suite has 13 cards. Within those 13 cards, the face value goes from two to ace (13). We now have some options for how to loop through...
