Do you know the rules?

Stricter Expression Evaluation Order in C++17

by Bartlomiej Filipek

From the article:

C++ has many dark corners and many caveats that can cause you to scratch your head in confusion. One of the issues we had until C++17 was the evaluation order of expressions. In this blog post, I’ll show you the new rules that we got in C++17 that made this complicated term much simpler and practical.

Here are the main points for today:

• What’s the case with make_unique vs unique_ptr<T>(new T) in a function call.
• What are the new rules for C++17?
• Are all bugs fixed and now well defined?

Let’s go.
