Forwarding

    Modern C++ In-Depth — Perfect Forwarding

C++Now 2022 Trip Report

by Timur Doumler

From the article:

From May 1 to May 6, 2022, I attended the C++Now conference in Aspen, Colorado. This was my third time speaking at C++Now (I also attended in 2016 and 2019), and in my opinion it was the best edition of C++Now so far!

Highly non trivial.

Assignment for optional<T>

by Barry Revzin

From the article:

Let’s talk about assignment for optional<T>. I realize this is a fraught topic, but I want to try to build up proper intuition about how assignment has to work, especially since the debate around this topic has been fairly underwhelming. This post will almost exclusively discuss copy assignment (i.e. the one that takes an optional<T> const&), since everything just follows from that...

How do you do it?

Writing a sort comparison function part 1, part 2, part 3, part 4

by Raymond Chen

From the article:

I’ve noted in the past that a sort comparison function must follow certain rules, and if you violate those rules, very strange things happen. So what are some patterns for writing sort comparison functions that don’t break the rules?

Most of the time, sorting can be reduced to key comparison: From each element being sorted, you generate a sort key, and those sort keys are compared against each other...

The Ranges Library in C++20: More Details

by Rainer Grimm

From the article:

Thanks to the ranges library, working with the Standard Template Library (STL) is much more comfortable and powerful. The algorithms of the ranges library are lazy, can work directly on the container, and can easily be composed. But there is more to it...

Check Types with Concepts

by Rainer Grimm

From the article:

Concepts are a powerful and elegant tool to check at compile time if a type fulfills. Thanks to static_assert, you can use concepts as a standalone feature: static_assert(Concept<T>)...
