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.

Addressing pointers – the boogeyman of C programming

Before we begin our understanding of declaring, initializing, and using pointers, we must address some common misconceptions and unavoidable truths about C pointers.

C pointers are often considered one of the most troublesome concepts in C, so much so that many modern languages claim to have improved on C by removing pointers altogether. This is unfortunate. In many cases, this limits the language's power and expressiveness. Other languages still have pointers but severely restrict how they may be used.

Pointers in C are one of its most powerful features. With great power comes great responsibility. That responsibility is nothing more than knowing how to correctly and appropriately use the power that is given. This responsibility also involves knowing when not to use that power and to understand its limits.

Untested and unverified programs that incorrectly or haphazardly employ pointers may...
