CppCon 2025 will kick off on Monday, September 15 with Bjarne Stroustrup back delivering the opening keynote in Aurora.

Bjarne’s opening keynotes for CppCon are one of the most anticipated and most watched talks in C++. His talks are always among the most viewed presentations on the CppCon YouTube Channel.

 

From his talk description:

Concept-based Generic Programming

This talk presents programming techniques to illustrate the facilities and principles of C++ generic programming using concepts. Concepts are C++’s way to express constraints on generic code. As an initial example, it provides a simple type system that eliminate narrowing conversions and provides range checking.

Concepts are used throughout to provide user-defined extensions to the type system. The aim is to show their utility and the fundamental ideas behind them, rather than to provide a detailed or complete explanation of C++’s language support for generic programming or the extensive support provided by the standard library.

The final sections briefly present design rationales and origins for key parts of the concept design, including use patterns, the relationship to Object-Oriented Programming, value arguments, syntax, concept type-matching, and definition checking. They also mention static reflection, a C++26 improvements in the support of general programming.

Be at CppCon again this year as Bjarne Stroustrup flies us above this complex landscape of issues and shines a spotlight on the most important things to know, and to think about, in C++ in 2025. Come to the talk, bring your questions, and don’t miss out!

Registration is now open so don’t miss out on CppCon 2025 this September 14-19. Register today!

 

 

 

 

The CppCon 2025 field trip will be to the Wings over the Rockies Air and Space Museum near the conference in Aurora, CO.

Join us Sunday, September 14th to experience aerospace history – the museum has a large collection of airplanes, rockets, engines, and even a replica Apollo guidance computer on site. We will have lunch catered by Curtis Park Delicatessen, a delicious lunch spot local to Denver and Boulder.

 

If you are arriving for CppCon 2025 by September 14, Sunday morning, this is your opportunity to get to know some of your fellow attendees while learning about aerospace history.

See the CppCon 2025 Field Trip page for details.

This year’s field trip is sponsored by the North Denver Metro C++ Meetup.

 

 

 

The above photo is from CppCon 2024 by CppCon’s photographer, Jonathan Phillips. Not only do I want to share this brilliant photo, I also want to announce CppCon 2025 dates, September 13 – 19 2025, save the dates now!

CppCon 2024 just wrapped up and was an amazing conference. For an early preview of what happened, see Herb’s keynote, Khalil’s keynote, Amanda’s keynote, David’s keynote, and Daveed’s keynote.

Videos of all our other Main Program sessions will start to be published on our YouTube channel, one a business day, starting in November. If you want access to this year’s CppCon videos as soon as they are available, then have we got something in store for you! Check out our Early Video Access option.

Trip Reports

I’ll update this post as trip reports are published. If you see a CppCon 2024 trip report published or you’d like your trip report to be included, please send us a note. You can see some short reports on LinkedIn and on Twitter.

Thanks

A conference the size of CppCon doesn’t just happen. There are a lot of heroes that work hard to make this happen. You’ll find many of their names on our staff page which lists the organizers, program committee, volunteers, and vendors.

You’d find more names (and faces) on the presenters page for this year’s conference which lists presenters from the Main Program, panels, Poster Program, Open Content sessions, and lightning talks.

As much as all of these people work hard so that we are providing the best that we can in technical content, food, production values, live music, comfortable ambiance, and supportive environment, none of those is the most important part of CppCon.

Returning attendees know that the most important part of CppCon is the opportunity to engage with the attendees (including the presenters), who are tackling some of our most challenging problems, with creative and innovative techniques, using powerful tools provided by C++ and the C++ community.

Above, you’ll see the faces of the most important part of CppCon, the attendees. (I’ve not matched faces to the registration list to verify that no one is missing, but I think most of us are in the photo.)

This year, more than any other, you are all my heroes.

I look forward to seeing you all next year.

Conference Chair

 We’ve previously announced keynotes by Herb Sutter on what lies ahead for C++, Khalil Estell on Exceptions in Firmware, David Gross on going “ultrafast”, and by Amanda Rousseau on changing our C++ Security mindset.

We’re now pleased to announce the our final conference keynote: Daveed Vandevoorde will be talking about Reflection, a topic that Herb Sutter mentioned in his keynote announcement. Reflection has the opportunity to transform C++ in a profound way and Daveed’s talk is going to shed light on why that opinion is shared by so many.

From Daveed’s talk description:

Gazing Beyond Reflection for C++26

In less than a year since its original publication, the WG21 proposal “Reflection for C++26” (P2996) has made good progress towards its titular goal.  From its inception, we intended that design to offer a modest-but-useful set of features with a solid foundation on top of which we will be able to incrementally grow an easy-to-use, rich, and extensible C++ meta-programming framework.  This keynote will review some of the fundamental tools proposed in P2996 and follow up with a vision for some additional capabilities that we’re working on.

Registration is open so don’t miss out on CppCon 2024 this September 15-20. Register today!
