Our mascot for this level is the magpie, one of the most intelligent nonhuman species on earth. They are capable of elaborate social rituals and usage of tools.

This first level of the book may be your first encounter with the programming language C. It provides you with a rough knowledge of C programs, their purposes, their structures, and how to use them. It is not meant to give you a complete overview; it can’t, and it doesn’t even try. On the contrary, it is intended to give you a general idea of what C is all about, open up questions, and promote ideas and concepts. These then will be explained in detail throughout the book.
