  What does that mean ?

    If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.

      Or don’t look into those things if you wish to remain sane

        Templates are cool as fuck tho… For like 5 minutes until you go insane

        yeah, zig and rust have the same concepts but much better thought and structed

      Translation: “We’ve made the preprocessor a first-class language feature!”

    it means rust is cool as fuck

    • Hadriscus@jlai.lu ⁨4⁩ ⁨weeks⁩ ago

      aren’t they talking about C++ ?

        C++ has pretty much no compile-time checks, while Rust’s overengineered syntax allows it’s compiler to catch vast majority of your everyday errors during compilation.

        Rust is a very modern replacement for C /C++.

    Overengineered mess

  C++ has a lot of terrible language features because it would allow some 8 bit embedded CPU to dynamically change from LSB to MSB ordering in the middle of decoding some input. 🙈

  does anyone actually follow whatver the comittee sees as best practices?

  source

  • e8d79@discuss.tchncs.de ⁨4⁩ ⁨weeks⁩ ago

    I think the closest to an actual answer you will find are the cpp core guidelines.
