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.

Working with Files

We have seen how to get data to and from the console via output and input streams. The next step in our exploration of input and output streams is to be able to access a persistent storage mechanism, one where we can save our data, exit the program, and then use it later. Data stored persistently, from one invocation of a program to the next, is saved in a file via standard file operations. Persistently stored data—that is, files—not only exists from one program invocation to the next but also remains in existence after the computer is turned off and then restarted.

In persistent storage, files are the basic entity of storage. In this chapter, we will present the essential properties of files and some basic manipulations that can be performed on them. We will also consider some of the functions that are unique to file manipulations. We will touch briefly on the function of the filesystem...
