I don't know if there is a book that can teach us everything about C, and I honestly don't
think it can exist. So the only path we can follow in order to learn C is to start with simple
books, and after more specific ones in some programming area, and so on, depending on what
is the OS we are going to use it, the specific area [there are so many] we are interested, the background
that we already have, and so on.
