How std::any Works
by Jonathan Boccara
From the article:
In the previous post we’ve seen a very nice technique to use value semantics with inheritance and virtual methods, which was made possible by std::any.
Given its usefulness, it would be interesting to better understand std::any. Indeed, std::any is sometimes said to be “the modern void*“. But it does much more than a void*...

Abbreviated Function Templates and Constrained Auto
by Sy Brand
From the article:
Declaring function templates in C++ has always been quite verbose. C++20 added a new way of doing so that is more terse and more consistent with lambdas: abbreviated function templates. This short post will show how to use this syntax and how it applies to C++20 concepts...

12 Different Ways to Filter Containers in Modern C++
by Bartlomiej Filipek
From the article:
Do you know how many ways we can implement a filter function in C++?
While the problem is relatively easy to understand - take a container, copy elements that match a predicate and the return a new container - it’s good to exercise with the Standard Library and check a few ideas. We can also apply some Modern C++ techniques.
Let’s start!

ACCU 2021 will be held online March, 10-13.
ACCU 2021 Accepting Volunteer Applications
by ACCU
From the announcement
It is our pleasure to announce the 1st year of the ACCU Conference Volunteer program! We are inviting students and young coders with an interest in C++ and software development to attend the March 10-13, 2021 online conference as Volunteers.
The Volunteer program is an excellent way for students and young coders with an interest in C++ and the development process in general to learn about language and make lasting connections with the community.
Volunteers will receive free registration.
Volunteers will handle various tasks during the conference, such as assisting at the online-help desk, in the -lobby, or in the -exhibitor hall.
Students from all fields of study are welcome to apply.
Please note that the deadline is the 16th of February

PVS-Studio can currently analyze programs written in C, C++, C#, and Java. It also supports some C++ language extensions, for example, C++/CLI and C++/CX. In 2021, we do not plan to implement support for new languages, but we plan to expand the analyzer. We want to support several new compilers (C, C++) for micro controllers and some development environments, such as CLion.
PVS-Studio Roadmap 2021
by Andrey Karpov
From the article:
We will continue to support the MISRA C and MISRA C++ coding standards. However, it's time to also support a more modern set of rules described in The AUTSAR C++14 Coding Guidelines. This document is the MISRA C++:2008 standard update, and is also based on leading code standards and research papers prepared by AUTOSAR.

"Contract support" is one of the things actively developed for C++.
Contracts, Preconditions & Invariants
By Andrzej Krzemienski
About the article
This blog post is an introductory material, demonstrating what a contract is, how preconditions and invariants can be derived from the contract, and how this process can help detect bugs. Two points stressed in this post are: (1) preconditions and invariants are not “contracts” and (2) only a subset of contract-related bugs can be detected through preconditions and invariants.

Barriers and Atomic Smart Pointers in C++20
by Rainer Grimm
From the article:
In my last post, I introduced latches in C++20. A latch enables it threads to wait until a counter becomes zero. Additionally, to a latch, its big sibling barrier can be used more than once. Today, I write about barriers and present atomic smart pointers...

std::jthread and cooperative cancellation with stop token
by Hitesh Kumar
From the article:
A std::jthread instance represents an automatically joining and cooperatively cancellable thread. std::jthread has an exception-safe thread termination flow compared to std::thread and can replace it in most situations with little or no code changes...

Inheritance Without Pointers
by Jonathan Boccara
From the article:
Inheritance is a useful but controversial technique in C++. There is even a famous talk by Sean Parent called Inheritance is the base class of evil. So inheritance is not the most popular feature of the C++ community.
Nevertheless, inheritance is useful, and widely used by C++ developers.
What is the problem of inheritance? It has several problems, and one of them is that it forces us to manipulate objects through pointers...
