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.

One day, when you come home, you start craving a pie, so you decide to make one. The reason you will bake a pie is not that you wish to cook, but to satisfy your desire for pie. However, to be able to get the pie, you need to perform several steps. First, you need a recipe, and then you need to get all of the ingredients. When you acquire them, you will follow each step in the recipe. Then, finally, after the pie has been in the oven and cooled down a bit, you can enjoy your well-deserved treat.

You just performed a few tasks in sequence. Some of them need to be completed in the right order, while others can be done in any order (or, at least, in a more relaxed order). You must turn on the oven before you can bake the pie, but it is not essential that you bring out the flour before the butter.

Programming is like baking a pie. We will have goals, such as we want pie, and to be able to achieve that goal, we will need to do several things: in some...
