Review of mini-book «60 terrible tips for a C++ developer»

Level of difficultyEasy

I wrote a small e-book about terrible tips for C++ developers. Actually, it describes bad programming practices and explains why it's better to avoid them. However, every chapter of this mini-book starts with a terrible tip — just for fun.


60 terrible tips for a C++ developer


By the way, these tips may seem artificial but believe me, they are based on the real experience. In other words, the described terrible tips occur in developers' lives — that's why it's worth discussing them. First of all, this book will be useful for junior developers. But more skilled C++ developers can also find interesting and useful tips.


Even though it's a mini-book, it clearly does not fit into the Habr format. Too many words. So, I decided to write here the review. Here is the link to find the full version of the mini-book: 60 terrible tips for a C++ developer.


If you still hesitate whether to read it or not, below you will find a list of terrible tips that will be discussed in the mini-book.

Blender, PVS-Studio, std::clamp
If you regularly use a static code analyzer, you can save time on guessing why the new code doesn't work as planned. Let's look at another interesting error — the function broke during refactoring, and no one noticed that. No one — except for PVS-Studio that can automatically scan the project and email the report to us.

Re-checking PascalABC.NET

Welcome all fans of clean code! Today we analyze the PascalABC.NET project. In 2017, we already found errors in this project. We used two static analysis tools (more precisely, plugins for SonarQube): SonarC# and PVS-Studio. Today, we analyze this project with the latest version of the PVS-Studio analyzer for C#. Let's see what errors we can find today, especially when our analyzer has become more advanced and got new features: it can find more exquisite errors and potential vulnerabilities.
