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.

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. We could then build programs with those multiple files. We also explored simple yet efficient ways to use the preprocessor without overusing it. Lastly, we saw how to build a multi-file program by specifying each .c file on the compiler command line.

This chapter is 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 variables and functions...
