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.

Understanding Memory Allocation and Lifetime

Every instance of a value—be it a literal, an intrinsic data type, or a complex data type—exists in memory. Here, we will explore various ways in which memory is allocated. The different mechanisms for memory allocation are called storage classes. In this chapter, we will review the storage class we've been using thus far, that of automatic storage, as well as introduce the static storage class. We will also explore the lifetime of each storage class, as well as introduce the scope of a storage class—internal versus external storage.

After exploring automatic and static storage classes, this chapter paves the way for a special and extremely flexible storage class—that of dynamic memory allocation. Dynamic memory allocation is so powerful and flexible that it will be introduced in Chapter 18, Using Dynamic Memory Allocation, with the creation...
