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.

Working with packages to share code

In software developer culture, sharing code for free is very natural. This makes the industry unique as programmers share and use each other's code all the time. Using someone else's solutions to a problem is as natural as sharing my good ideas and code. It is usually wise to reuse the work of others as the code is often well developed, well tested, and well maintained. In software development, the term open source is well known. It means that someone has an idea for an application, writes the code for it, and then shares it online. Others are then encouraged to help with the development of this project. Several programmers will join in, and together they keep the project going. Everyone interested can then use this code free of charge.

The code that's developed in such a project is often in the form of one or several modules. If you want to use such a module, you must find it, and then you need to download it. The question is,...
