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.

Accessing individual structure elements of the array within a structure

Accessing structure elements and sub-elements is a matter of layering access from the topmost, or outer structure elements, to the bottommost, or inner sub-structure elements. We have already seen simpler versions of this in the earlier sections of this chapter.

We must, however, be mindful of the data type of the sub-element being accessed. In particular, we must pay attention to whether the member element is a direct intrinsic type or structure or whether it is a pointer to another intrinsic type or structure. Being clear about differentiating member elements and pointer elements determines which notation is required—dot (.) or arrow (->) notation.

Given the preceding definition of Deck, consider the following access to each of its various elements and sub-elements:

Deck deck;

deck.cardsDealt = 0;
deck.bIsShuffled = false;
deck.shuffled[0] = NULL;
deck.ordered[3].suit = spade...
