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.

Using Dynamic Memory Allocation

Not all data can be allocated statically or automatically. Sometimes, the number of items to be manipulated is not known beforehand; that number can only be known at runtime and may vary from run to run, depending on external inputs (user input, files, and so on). In the preceding chapter, we examined automatic and static memory allocation. We now stand on the threshold of an incredibly powerful feature of C – dynamic memory allocation and manipulation. Once we pass this threshold, many flexible dynamic data manipulations will be available to us. We will briefly introduce many of these data structures and their uses in this chapter.

As mentioned in the preceding chapter, dynamic memory is unnamed, so it can only be manipulated via pointers. Furthermore, dynamic memory has a different lifetime than either automatic or static memory.

The following topics will be covered in this...
