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 whitespace

When a <space> or <newline> character is not required to delimit a portion of C code, it is considered whitespace. Whitespace can also be <tab>, <carriage return>, and some other obscure characters. However, the use of tabs in C source files is discouraged since the program listing may look different on someone else's computer or when the source code is printed, thereby diminishing clarity and obfuscating your original intent.

Always use spaces instead of tabs in your source code files.

We write <newline> to mean the start of a new line, which has the same effect as hitting Enter on your keyboard. <space> similarly is the same as hitting the spacebar at the bottom of your keyboard.

There are many opinions by as many programmers on how to effectively use whitespace. Some programmers feel strongly about using two spaces to indent a line while others are vehement about using four spaces. Others...
