Overview of this book

Learning how to code has many advantages, and gaining the right programming skills can have a massive impact on what you can do with your current skill set and the way you advance in your career. This book will be your guide to learning computer programming easily, helping you overcome the difficulties in understanding the major constructs in any mainstream programming language. Computer Programming for Absolute Beginners starts by taking you through the building blocks of any programming language with thorough explanations and relevant examples in pseudocode. You'll understand the relationship between computer programs and programming languages and how code is executed on the computer. The book then focuses on the different types of applications that you can create with your programming knowledge. You'll delve into programming constructs, learning all about statements, operators, variables, and data types. As you advance, you'll see how to control the flow of your programs using control structures and reuse your code using functions. Finally, you'll explore best practices that will help you write code like a pro. By the end of this book, you'll be prepared to learn any programming language and take control of your career by adding coding to your skill set.

Chapter 4: Software Projects and How We Organize Our Code

When we write software and our program grows, we will need to organize our code so that it is easy to read when we need to maintain it. An application can be hundreds of thousands or millions of lines of code long, so having it all in a single file is impossible. We will need to divide the code into multiple files, but how will we do this? And even if we put the code into separate files, then we'll have lots of files, so we will need to organize them into folders. How can we do this so that the compiler or interpreter can find them? How will we know where to look when we need to edit a part of the application? In this chapter, we will discuss this and learn about some patterns that we can use.

The following topics will be covered in this chapter:

  • Understanding code modules
  • The concept of a code project
  • Working with package managers to share code
  • Delving into a namespace
  • Using namespaces to avoid...
