Modern C++ In-Depth — Move Semantics, Part 2
by Phani Adusumilli
From the article
In this installment, we'll take a look at how we might go about defining move semantics for our own custom types, should we need them.

Correct time tables.
Local Time
by Andrzej Krzemieński
From the article:
In this post we will see how to solve the task from the previous post, but display the time point in local time instead of system time. The solution is simple and takes only two additional lines (you can scroll down towards the end), but I want to take this opportunity to offer some reflections about the concepts of time zones and daylight saving time...

Defining Concepts with Requires Expressions
by Rainer Grimm
From the article:
In my last post "Define Concepts", I defined the concepts Integral, SignedIntegral, and UnsigendIntegral using logical combinations of existing concepts and compile-time predicates. Today, I use Requires Expressions to define concepts...

C++20 Ranges Algorithms - 7 Non-modifying Operations
by Bartlomiej Filipek
From the article:
C++20’s Ranges offer alternatives for most of <algorithm>'s'. This time I’d like to show you ten non-modifying operations. We’ll compare them with the “old” standard version and see their benefits and limitations.
Let’s go...

New C++ features in GCC 12
by Marek Polacek
From the article:
Version 12.1 of the GNU Compiler Collection (GCC) is expected to be released in April 2022. Like every major GCC release, this version will bring many additions, improvements, bug fixes, and new features. GCC 12 is already the system compiler in Fedora 36. GCC 12 will also be available on Red Hat Enterprise Linux in the Red Hat Developer Toolset (version 7) or the Red Hat GCC Toolset (version 8 and 9).
Like the article I wrote about GCC 10, this article describes only new features affecting C++.
We implemented several C++23 proposals in GCC 12. The default dialect in GCC 12 is -std=gnu++17; to enable C++23 features, use the -std=c++23 or -std=gnu++23 command-line options. (The latter option allows GNU extensions.)
Note that C++20 and C++23 features are still experimental in GCC 12...

Policy
by Rainer Grimm
From the article:
Thanks to templates, there are new ways of software design. Policies and traits are two commonly used idioms in C++.

Type Erasure
by Rainer Grimm
From the article:
Type erasure based on templates is a pretty sophisticated technique. It allows you to bridge dynamic polymorphism (object orientation) with static polymorphism (templates).

Define Concepts
by Rainer Grimm
From the article:
There are two ways to define a concept: You can combine existing concepts and compile-time predicates, or you can apply a requires expression in four different ways...
