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.

Chapter 24: Working with Multi-File Programs

To solve large problems, we often need large programs. All the programs we have developed so far have been small – under 1,000 lines of code. This is a reasonable size for a medium-sized program to, say, create a simple game, perform a basic but robust utility, or keep notes that may consist of anywhere between 10,000 to 100,000 lines of code. A large program would manage a company's inventory, track sales orders and bills of materials, provide word processing or spreadsheet capabilities, or manage the resources of the computer itself – an operating system. Such programs would consist of anywhere from 100,000 lines of code to a million or more lines of code. Such programs would have teams of programmers and require hundreds of man-years of effort to create and maintain.

As you gain experience in programming, you may find that the kinds of problems you work to solve become larger. Along with that, you will find that...
