Coding is everywhere. From your TV through to the International Space Station, you’ll find millions of lines of code controlling and delivering the services that we take for granted. Behind all this code are the programmers who develop our digital world, using a multitude of different languages to weave the fabric of the Internet, operating systems, games and modern entertainment. Whether it’s inside the world’s most powerful supercomputer or automating tasks aboard the ISS, scripting is the key to effective interaction between systems and people. We cover C++, Python, and Linux Scripting within these pages. There’s a huge section of project ideas, type-in listings, and in-depth looks at how code works. But first, let's begin with a good foundation. C++ is an amazing programming language. Most of what you see in front of you when you power up your computer, regardless of whether you’re using Windows, macOS or Linux, is created using C++. Being able to code in C++ will open a whole new world for you, in terms of desirable professional skills and the ability to code amazing apps and games.
