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.

Defining storage classes

C provides a number of storage classes. These fall into the following two general categories:

  • Fixed storage allocation: Fixed storage allocation means that memory is allocated in the location where it is declared. All fixed storage is named; we have called these variable as identifiers, or just variables. Fixed storage includes both the automatic storage class and the static storage class. We have been using automatic storage for every variable thus far. When you declare a variable and—optionally—initialize it, you are using automatic storage. We will introduce static storage later in this chapter.
  • Dynamicstorage allocation: Dynamic storage allocation means that memory is allocated upon demand and is only referenced via a pointer. The pointer may be a fixed, named pointer variable, or it may be a part of another dynamic structure.

Two properties of storage classes are their visibility—...
