Linux is an excellent choice for C programming. It has arguably the easiest setup and the best support for C programming out of the three operating systems covered in this book.
Using Linux also allows you to take the ethical high road and feel good about supporting free software.
One issue with describing the setup for Linux is that there are many Linux distributions with different software.

sudo apt-get update...
