One of the great qualities of this book is precisely to follow that order. The structure is clear, and every theoretical explanation is illustrated with an example. The code is built gradually, allowing to follow the thread proposed by the author, Larry Ullman, a born teacher!
During my training, I had the opportunity to communicate with him, and I must say it kindly answered each of my requests. You should also remember that for every book he wrote, a forum is available. In my case, I received a response from the community in the few hours after my request!
In short, every reason to be satisfied with this purchase!
