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.

Introducing the filesystem essentials

A filesystem is a component of an operating system that controls how files are stored and retrieved. The filesystem typically provides a naming and organization scheme to enable the easy identification of a file. We can think of a file as a logical group of data stored as a single unit. A filesystem provides the ability to manage an extremely large number of files of a wide range of sizes, from very small to extremely large.

There are many different kinds of filesystems. Some are specific to a given operating system while others offer a standard interface and appear identical across multiple operating systems. Nonetheless, the underlying mechanisms of a filesystem are meant to guarantee various degrees of speed, flexibility, security, size, and reliable storage.

The filesystem is meant to shield both the operating system and programs that run on it from the underlying physical details of the associated storage medium. There...
