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 a file path

A file path can be eitheran absolute file path or a relative file path. In an absolute file path, the base of the file hierarchy is specified, along with the name of each directory and subdirectory to the final directory where the filename exists. The base of the file hierarchy is also called therootof the file hierarchy tree. In a relative file path, only the portions of the path relative to the current program location are required.

The structure of an absolute file path varies from one filesystem to another. It may have a generic root or it may begin with the name of the device where the file hierarchy exists. For instance, on Unix and Linux systems, all files exist somewhere in the file hierarchy with the root beginning with /. On Windows, the root of a file hierarchy typically begins with a device identifier, such as D:.

Thankfully, there are many common features that we can rely upon. Once the base of the file hierarchy, or the...
