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.

Understanding object-orientated programming

The main idea within object-oriented programming is to model the code in the same way as we as humans look at the world.

Even if you've never thought about it, we are always classifying things and grouping things together using abstraction. We can talk about vehicles, and we have shared knowledge of what is included in this group. Cars, bicycles, boats, and airplanes are, while pencils, ducks, and swimsuits are not.

I could say, I need to go to town. Can anyone lend me a vehicle?

You will interpret this in such a way that the actual kind does not matter, but it must be something that can transport me to town. It could just as well be a car as it could be a skateboard.

Grouping things into these abstractions make our lives easier as we will not go into details every single time, we talk about something. I can ask for a vehicle instead of describing that I need a device that can transport me from my current location to town...
