What Hacker News says?
Some of C++ features are great, as recently discussed on the Linux kernel mailing list. However for many of Cs usecases, they are not appropriate, like exceptions and RAII in embedded. Once you start disabling major features those 'power tools' become far less attractive. Also, to extend the metaphor, hand tools are usually obvious and easy to use while power tools can have very long manuals. See for example the 275…

HN discussionSo, what programmers wanted (yes, already before C++ got this) was what are called "destructive move semantics". These assignment semantics work how real life works. If I give you this Rubik's Cube now you have the Rubik's Cube and I do not have it any more. This unlocks important optimisations for non-trivial objects which have associated resources, if I can give you a Rubik's Cube then we don't need to clone mine,…

HN discussionRead through https://www.learncpp.com . You'll get a complete refresher on the language, but it will be using modern C++ stuff (modern in this case means C++17). For C++20 and newer, honestly, the only big feature that I ever use is concepts, although I do also use the new struct initialization syntax[0].

HN discussionIt depends on what problem you are trying to solve, your programming style, and the size of your team. I personally will avoid C++ if possible because it has too much complexity, too many "gotchas", and there are better choices available (Rust, Go, Ada, C, etc.). Some people like C++ and that is fine. They can use it. I will use something else if at all possible. https://en.wikipedia.org/wiki/Criticism_of_C%2B%2B ht…

HN discussionThere are discussions in many places about this, including right here on HN. I encourage you to Google it. Here are some examples: https://news.ycombinator.com/item?id=24537267 https://www.cppstories.com/2018/01/pimpl/#pros-and-cons It used to be a widely advertised technique maybe a decade ago, but it has long gone out of style.

HN discussionSorry, I still don't get how it's different from C++, and my point wasn't about `auto` but rather about `std::vector v2`: std::vector v2 (v1.begin() + 1, v1.begin() + 2); > However, in the provided example, the Rust type checker can use the provided clue to narrow this down to an exact type The Rust example is incomplete and its RHS by the time it gets to `.collect()` within the context of `iterator` has to be bound…

HN discussionLess known fact is that it's called C++23 because there are 23 ways to initialize a variable. Of course, it's a joke. In reality C++23 has only 20 ways to initialize a variable: https://www.cppstories.com/2022/init-string-options/ https://blog.tartanllama.xyz/initialization-is-bonkers/
