An experimental Forward Iterator written from scratch to boost up hand-made containers.
Writing a custom iterator in modern C++
by Internal Pointers
From the article:
Iterators are one of the building blocks of the Standard Library containers, but they are also useful when you want to provide the ability to iterate over elements of a custom container that you wrote yourself. Adding iterators to your containers will make them compatible with the range-based for loops and the C++ Algorithms library: a collection of functions for searching, sorting, counting and manipulating containers, based on iterators.

Utah C++ Programmers has released a video on vcpkg:
VcPkg: The Open Source Cross-Platform Package Manager from Microsoft
by Richard Thomson
From the video description:
Richard Thomson gives us an informal introduction to vcpkg on both Windows and Linux.
Here's what we want from a package manager:
- works identically across platforms
- integrates with existing builds
- easy to find packages
- easy to consume packages
- can use prebuilt binaries to save build time
- can use local private packages as easily as public packages
- works with continuous integration systems
- doesn't require languages other than C/C++How well does vcpkg fit the bill?

SonarSource has been working all year to improve C++ support. Recently we adjusted standard-specific rules to run only on code compiled to that standard. So C++98 rules will no longer raise issues on your C++17 code, and vice versa!
C++ analyzer helps developers to write C++17 compliant code
by Alexandre Gigleux
From the article:
C++17 standard is out for a while now and supported by the C++ analyzer running on SonarCloud. We did an effort in the past years to fix false-positives/false-negatives related to the new constructs/features of C++17. That was great but not enough to help you be more familiar with the standard and take the best out of it.
This is why we are happy to introduce a first set of rules dedicated to C++17. With these rules, we hope you will take advantage of the new features of C++17 and write more reliable and maintainable C++17 code.
C++ analysis is available free for open source projects in SonarCloud, and in commercial editions of SonarQube.

I'm Proud to Present my New Book: C++20
by Rainer Grimm
From the article:
I'm proud to present the early release of my book to C++20 on LeanPub. The book is 50 % done and has more than 300 pages and 150 code examples of content. I will update the book at least two times in 2021. Of course, you will get each update of the book

This is the press release of the New Year's version of the PVS-Studio 7.11 analyzer. Since the new version includes only a few enhancements, let's take this opportunity to recall the options for free PVS-Studio use.
PVS-Studio 7.11 Release: IAR Arm, Diagnostics, FREE-FREE-FREE-FREE
by Andrey Karpov
From the article:
Support of the IAR Arm compilers is now available in the pvs-studio-analyzer utility. This family of compilers was previously supported only in the CLMonitor.exe utility on Windows. Now users of PVS-Studio for Linux can check the code written for these compilers as well. We added interception of compiler calls via ld-linux to the pvs-studio-analyzer utility.

An introduction to std::any and comparison with void*.
std::any - comparison with void* and motivating examples
by Hitesh Kumar
From the article:
std::any is often compared with void* because the latter has been the de-facto choice for storing or passing the arbitrary objects in C++ since the outset. std::any is not a replacement of void*, but it is a safer substitute for the boilerplate patterns built around void*. Nevertheless, a comparison between the two is required for a better understanding of std::any.

New video on the CopperSpice YouTube Channel:
C++ Memory Model
by Barbara Geller and Ansel Sermersheim
About the video:
In this video we examine the C++ memory model and explain why it is a completely separate component from the multi-threading library added in C++11. We also look at the development of the memory model and its purpose in the C++ standard.
