Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Summary

In this chapter, we once again demonstrated the importance of developing a complex program step by step from simpler yet operational programs. Here, we took the program from Chapter 22, Working with Files, and built upon it to create a template program, getoptFiles.c. We saw that getoptFiles.c can read from either stdin or a file and can write to either stdout or another file. We then built upon getoptFiles.c, which did little else than open streams, to read lines of text representing names and output those lines as they were read. In the process of doing that, we learned about the subtleties of the fgets() and fputs() functions and how to use them to our advantage by wrapping each in a more capable function of our own.

Lastly, we took the concepts of sorted names from Chapter 22Working with Files, and applied them to files using dynamic memory structures to accommodate large and unknown numbers of data...
