C++ Best Practices
C++ Best Practices
45ish Simple Rules with Specific Action Items for Better C++
About the Book
Note that this book is also available on Amazon in both color and black and white editions if you prefer a printed version.
As a C++ developer and trainer for 20 years, I have learned that there are many common mistakes that C++ developers of all experience levels make. This book distills that experience down into the most important things to address to make your code faster, easier to maintain, and more portable.
Most sections have one or more exercises that help you apply what is discussed in a practical way in the code you are currently working on
This book is intentionally concise! Expect short sections for each item! I use as few words as possible to get across the point and get you applying what you learned to your code.
If you follow me and watch all of my talks this book will present little new information to you. Why should you buy it then? Because I've consolidated the most important items and given you exercises to apply the rules in your code.

Reader Testimonials
Adam
I finished it yesterday and loved it. I almost wished it was longer but at the same time, I realize I’m able to remember every actionable piece of advice within. With so many styles and conflicting “best practices” out there, it’s helpful to a have a rigid set of techniques to just default to. I will recommend this book to future interns or other folks I get to work with in the future.
Matthew
Thanks for the great final version of the book. It's clear, concise and the references are a great way to expand on everything.
