Notebook C++
Tips and Tricks with Templates
About the Book
This book is part of a series which is called Notebook C++. The idea is that most of us have some kind of rules about do's and don'ts or tips and tricks to keep in mind. It is probably one of the most frequent questions I get during training classes. I have such a list too. In this series, I will publish mine.
My idea is to create multiple short books (ok what is the number of pages required to call it a book or short?) about various topics. I currently plan to share tips about templates (this book), lambdas, and trap-like situations like dangling references. There will probably be more.
Why several short books and not a single large one? Simply to give you a choice. Maybe you are already fine with one topic but have an interest in tips for another topic. Why then by a large book where you need only a portion of it? Another thing is I personally like printed books. There I find smaller ones more comfortable when carrying them around like on a train or airplane. Plus, they are not that heavy then, which is also a plus.
