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.

Code modules

If programs are used, they are also updated, and if you are the developer of a program, this means that you will need to edit the source code in order to add features and fix errors. If your code is not well organized, it will be hard to read and maintain because you will need much more time to find where to insert your new code or where that nasty error might be.

One measure to make your code easier to handle is to distribute it into several logical blocks. But how do we decide what will go into such a block? There are no fixed rules for how this is done, but the language you use might give you some hints, depending on how it wants you to structure the code. In the end, it is up to you to make the final decision.

The code we write is logically connected, so to be able to do something, we often need to do a couple of other things first. It is as if you wake up in the morning and, while still in bed, you remember that there is nothing at home to make breakfast with...
