Question C++23

[pierreyvessojic]

Hello @Daniel Duffy @APalley,

I am going to start the advanced course later this year, and I was wondering if you were planning to update the course with some of the new features from C++23 in the near future? If so, I guess it would be preferable to wait for the course update before starting it, no?

Thanks!

 

[Daniel Duffy]

Don't wait; start now.
95% of real-life C++ is C+11, so QN is already years ahead.

And knowing C++20 you can easily learn C++23 on your own.

C++23
Many low-level syntaxes, defect reports etc.

C++23 - Wikipedia

In February 2020, at the final meeting for C++20 in Prague, an overall plan for C++23 was adopted:[3][4] planned features for C++23 are library support for coroutines, a modular standard library, executors, and networking.

This is for experienced C++ developers in production environments. Nice to know of course, but you need to find where to use it in real life applications.

Ok got it I just finished the first C++ course and it was already quite a lot of information to process, but I still feel that I have just scratched the surface haha even more given that they now seem to keep adding new stuff every 3 years, almost feels like it never ends!

The real paradigm shifts were C++11 and then C++20. It's unlikely there will be another such shift for a long time.

That's a good thing! A while back (before C++11) C++ was almost rigor mortis.
Good news! new stuff coming up for the next 50 years

C++14 was a kind of fix. C++17 had some nice stuff. C++23 is beginning to converge with Haskell.

yeah, C++14 was a kind of fix. C++17 had some nice stuff. C++23 is beginning to converge with Haskell.

Haskell!!!!!

 

[Daniel Duffy]

Haskell!!!!!

Haskell Typeclasses == C++20 Concepts. haha

 

[Daniel Duffy]

And don't forget C++26 LOL

A follow-on remark: a number of useful features in C++11 (e.g. enable_if etc.) can now be done much more easily in C++20 Concepts.
C++20 Concepts are mathematically quite robust.
