CppCon 2019: C++20: C++ at 40--Bjarne Stroustrup

This year, CppCon 2020 is going virtual. The dates are still the same – September 14-18 – and we are aiming for the CppCon live event to have pretty much everything you’re familiar with at CppCon except moved online: multiple tracks including “back to basics” and a new “embedded” track; live speaker Q&A; live talk time zones friendly to Americas and EMEA (and we’re going to try to arrange around-the-clock recorded repeats in all time zones, where speakers who are available can be available for live Q&A in their repeated talks too, and we’ll do that if it’s possible – but we’re still working on it!); virtual tables where you can interact face-to-face online with other attendees just like at the physical event; virtual exhibitor spaces where you can meet the folks on your favorite product’s teams to ask them question face-to-face; pre- and post-conference classes; and even the CppCon house band playing live before every plenary session. All talk recordings will be freely available as usual on YouTube a month or two after the event, but everything else above will be available only live during CppCon week.

To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2020 – all the spirit and flavor of CppCon, this year all virtual and online!

C++20: C++ at 40

by Bjarne Stroustrup

Summary of the talk:

It is now 40 years since C++ (then called C with Classes) had its first non-research user. It is now 35 years since the first commercial release of C++. It is now 30 years since the start of the standards process.

So what is C++? I will try to explain what's great about C++, C++20, as a modern language, not treating it as a layer cake of features. Imagine you have never heard of C, C with Classes, or C++11. How do classes, templates, and lambdas fit together? What have constructors and destructors to do with exceptions? What's in the standard library? How can we start using C++?

Finally, I will make a few comments about how to get from older styles of C++ use to modern C++ and point to areas where we need to improve C++ further.

8 years of Meeting C++

8 years ago in 2012, Meeting C++ got started!

In 2012 Meeting C++ got started in July. Planned first to be a one off conference, now it is a successfull international conference and a platform for C++ on the internet.

Initial Support For C++20 Ranges--Casey Carter

Ready to try them?

Initial Support For C++20 Ranges

by Casey Carter

From the article:

We are happy to announce that Visual Studio 2019 version 16.6 contains the first user-visible pieces of C++20 Ranges support. We’ve been working on support machinery for a few releases now, but in this release the tip of the iceberg has finally broken the surface of the water and there are now some tools available for users. The Ranges implementation critically depends on C++ Concepts, and as such is usable with both MSVC and Clang in their C++20 Preview modes but not yet well-supported by IntelliSense. (Don’t worry, we’ll have proper IntelliSense support soon.)...

The yearly voting for the program of the yearly Meeting C++ Conference has started!

The voting on the talks for Meeting C++ 2020 begins!

by Jens Weller

From the article:

With today, you can start to vote on all submitted talks for Meeting C++ 2020! As 2020 is a bit special, it is less talks, but also this years conference will only feature one track, the voting will give me guiding in which talks to choose from speakers with multiple talks, but also will help to see which other speakers might should make it to the conference. Unlike prior years the main track can't be the mostly consisting out of the most popular talks of the voting.

C++20 Features and Fixes in VS 2019 16.1 through 16.6--Stephan T. Lavavej

C++20 Features and Fixes in VS 2019 16.1 through 16.6

by Stephan T. Lavavej

From the article:

We’ve been busy implementing C++20 features in MSVC’s compiler and Standard Library, and migrating the latter to microsoft/STL on GitHub – in fact, we’ve been so busy that we haven’t posted a C++ toolset changelog since the VS 2019 16.0 toolset changelog. So, here are the compiler features and STL features/fixes that have shipped for production use in the last year.

As a reminder, the /std:c++17 and /std:c++latest compiler options are necessary to use C++17 and C++20 features...

The C++ Lambda Story Book--Bartlomiej Filipek

Getting up to date.

The C++ Lambda Story Book

by Bartlomiej Filipek

From the article:

Lambda Expressions appeared in C++11, and since then they become one of the most distinguishing features of Modern C++. What’s more, with each revision of the Standard the ISO Committee improved the syntax and capabilities of lambdas, so they are even more comfortable to use.

Read on to see how you can learn all the details of this powerful modern C++ feature.

How to ask for C++ coding help--Kate Gregory

The good practices exist also to ask for help.

How to ask for C++ coding help

by Kate Gregory

From the article:

Lately a lot of people have been asking me for help as they write C++ code. I’m usually happy and able to help. There are times, though, when I either cannot help, or choose not to help. I thought it might be helpful to explain some of these a little. It’s quite likely that other members of the community have a similar set of guidelines in their heads for when they do and don’t help people with code...
