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.

Summary

In this chapter, we expanded our knowledge of streams to text and binary streams. We learned about the various stream properties and briefly explored file functions that manipulate text streams and binary streams. We also learned about some common file functions, including fopen(), fflush(), and flclose(). These functions were demonstrated in three different programs that obtained input and output filenames in various ways. The first way hardcoded filenames into the program. The second way gave the user a prompt for each file and read the filenames with scanf(). The last way received filenames from command-line arguments via argv.

With the knowledge we have gained from covering these topics, we are ready to start with the next chapter, where we'll begin working on these simple programs, enhancing the command-line argument process and performing useful work on the input to generate meaningful output.
