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 Pointers

A pointer is a variable that holds a value that is the location (or memory address) of another value. The pointer type not only identifies the variable identifier as a pointer but also specifies what kind of value will be accessed at the location held by the pointer.

It is essential to learn how to verbally differentiate the address of notation (a pointer value) versus the target of notation (the value found at the address that the pointer points to). In this chapter, we will strive to demystify C pointers.

Learning how to properly use pointers expands both the expressiveness of C programs as well as the range of problems that can be solved.

The following topics will be covered in this chapter:

  • Dispelling some myths and addressing some truths about C pointers
  • Understanding where values are stored and how they are accessed
  • Declaring pointers and naming...
