???????? Old vs. New C++—Which Wins?

In his ACCU 2025 keynote, Matt Godbolt puts modern C++ to the test by writing two ZX Spectrum emulators: one in classic C++11 style and another with constexpr, coroutines, and modules.

Will the old dog learn new tricks? Find out!

accuconference.orgACCU 2025 : Teaching an Old Dog New Tricks: A Tale of Two Emulators - Matt GodboltAs a self-proclaimed C++ dinosaur, I set out to prove that my comfortable, battle-tested ways of writing code (somewhere between C++11 and C++14) were clearly superior to all this modern constexpr-everything, coroutine-laden C++

Ok, I guess I'll do an #introduction on this account now:

I'm Eleanor, a software engineer working mostly in #cplusplus and #rust these days. My background is in math, physics, and scientific computing, but I'm currently moving into a new thing that's still programming in Rust and C++, but in a very different domain than what I'm used to (and for a lot more users).

When I'm not staring at text on a screen or managing other aspects of my life, I play the violin and the piano, and I read science fiction and fantasy books. These are few and far between these days since there's always a lot going on.

This account is intended to focus mostly on my computer-related escapades.

and improved smart pointer support.

We've deprecated outdated features to align with the C++ standard library and modernized our build infrastructure for compatibility with the latest compilers.

Huge thanks to our community contributors for making this possible! Share your feedback below! #CPlusPlus #GSL #OpenSource #Community

I have run this exercise with multiple C++ developers from junior to senior. Its a simple task that can reveal strength/weakness in a devs understanding of what good C++ could look like.

Implement a reverse words function that works in-place on the string provided.
- Make it correct
- Make it performant
- Make it maintainable

Give it a go. I'll also post content warning hint(s) as replies.
