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 consisting of other structures

We have already seen how to create a Hand structure that consists of the Card structures, as follows:

typedef struct {
int cardsDealt;
Card card1;
Card card2;
Card card3;
Card card4;
Card card5;
} Hand;

Hand is a structure that represents a collection of cards dealt with that hand. In this case, Hand contains five individual instances of a Card structure, each of them named card1 through card5. The cardsDealtmember variable allows us to keep track of how many cards are in a hand.

Add the preceding structure definition to carddeck_2.c.

When you consider this structure, you might wonder why an array of Card structures is not used instead. Since an array is a collection of identical times, an array might be more appropriate than five named variables. In reality, using an array is an approach we will take later. For now, we want to explore accessing structures within structures. In the next section...
