Get ready for code smells, classic errors, and typos when checking the TDengine project using PVS-Studio. Developers could've prevented many of them if they had carefully designed the code in the first place, kept the logic simple, and avoided macros. Let's break down some of these errors and figure out how refactoring can help eliminate them completely. This time, we'll talk about writing code using the copy-paste method.

Get ready for code smells, classic errors, and typos when checking the TDengine project using PVS-Studio. Much of this is avoidable if we design code carefully from the beginning, keep the logic simple, and stay away from macros. Let's break down some code snippets and find ways to refactor them to leave bugs no room there. In the previous post, we had a good feed of the sausage code. In this article, I'll use a new example to show why macros are dangerous and why I dislike them.

The analysis of the TDengine project code using PVS-Studio reveals classic errors and typos. Developers could've avoided many of them if they had carefully designed the code in the first place, kept the logic simple, and avoided macros. Let's take a look at these errors and figure out how refactoring can help eliminate them completely. Sausage code This meme is the easiest way to illustrate what I mean. Unfortunately, Java programmers aren't the only ones writing "sausage code".

Your attention is invited to the final part of an e-book on undefined behavior. This is not a textbook, as it's intended for those who are already familiar with C++ programming. It's a kind of C++ programmer's guide to undefined behavior and to its most secret and exotic corners. The book was written by Dmitry Sviridkin and edited by Andrey Karpov. Why is it the chapter 12 of 11?

Your attention is invited to the tenth part of an e-book on undefined behavior. This is not a textbook, as it's intended for those who are already familiar with C++ programming. It's a kind of C++ programmer's guide to undefined behavior and to its most secret and exotic corners. The book was written by Dmitry Sviridkin and edited by Andrey Karpov. Program execution: trivial types and ABI Let's say we created a neat library to handle 2D vectors and added the Point structure.

5 lines of fortune: what program keeps under wraps Forget about ghosts! The true threats lurk in everyday things—like static_cast, which can unexpectedly drop all security efforts, and assert, which rapidly vanishes in a release build. Welcome to the world of self-made traps! Intro I explored the PVS-Studio warnings issued for the Xenia project in my previous article: "Realm of gaming experiments: potential developer errors in emulator creating".

C and C++ are iconic languages in which a huge amount of code is written. What path have they traveled to become ones? This article covers the emergence of C and the beginning of its official standardization. Also, you'll learn about C with Classes and its eventual transformation into C++. 1969 — 1973. C is born into the world 1969. Apollo 11 visits the Moon. AT&T Bell Labs develops a language we all know today as C. At this time, a Unix operating system is at the early development stage.
