Learn C Programming - Second Edition

By: Jeff Szuhay

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.

In this chapter, we took a single source file made up of many structures and functions that operate on them and grouped them into four source code files and four header files. We saw how we could – and should – group structures and functions that operate on them into a source file and a corresponding header file. All of the functions were related, in that they operated on the structures declared in that file's header file. These many source files were then compiled into a single program. After that, we built programs with those multiple files. We also explored simple yet efficient ways to use the preprocessor without overusing it. Lastly, we learned how to build a multi-file program by specifying each .c file on the compiler's command line.

This chapter was just an introduction to multi-file programs. In the next chapter, Chapter 25, Understanding Scope, we will expand our knowledge of multi-file programs so that we can both limit which...
