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.

Summary

In this chapter, the focus has been on organizing our code and how to name things so that we can avoid naming conflicts.

A book is divided into chapters to make it easier to read and navigate. In the same way, we want our code to be easy to read and understand. We don't have the concept of chapters in programming, but we do have modules. A module is a part of our application where the code is logically related; that is, one way or the other, it works with the code. A module is often defined as a separate code file.

In larger projects, we can end up with a large number of modules. Due to this, we need a way to organize them so that the compiler or interpreter can locate the correct file when all the pieces needs to be put together. We do this with the help of a project. We can see the project as a form of container for all our modules, but also for other resources that our application might use, such as images, configuration files, and so on.
