Stricter Expression Evaluation Order in C++17--Bartlomiej Filipek

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.

Template Specialization--Rainer Grimm

Template Specialization

by Rainer Grimm

From the article:

Templates define the behavior of families of classes or functions. Often it is required that special types or non-types may be treated special. To support this use case, you can specialize templates.

Template Argument Deduction of Class Templates--Rainer Grimm

Template Argument Deduction of Class Templates

by Rainer Grimm

From the article:

In my last post Template Arguments, I wrote about function template type deduction (C++98) and auto type deduction (C++11). Today I wear more modern hats. I start with automatic type deduction of non-type template parameters and class templates (C++17) and finish with automatic type deduction of concepts (C++20).

Reversing words of a string with ranges--Marco Arena

A new interpretation of a classical problem:

In this post I share the story of a “C++ aha-moment”, hence I use the hashtag #thatsarotate (resumed last Saturday at the Italian C++ Conference 2021 to honor our keynote speaker Sean Parent). Why not sharing your own stories of “C++ aha-moments” adding the same hashtag to your tweets, posts, or whatever? It would be really appreciated...
