If you have working code and want someone to critique it, post it on codereview.com. The write-to-video-RAM case is pretty specialized, and not the same as incrementing a string of ASCII digits and calling puts or fwrite on them in a loop. (Or manually storing them into a larger buffer for an eventual fwrite.) — Peter Cordes 29 secs ago

Q: Unsigned 64bit subtract-with-borrow in Standard C++

yuri kilochekI'm writing a (compile-time-)fixed-width unsigned big integer. To implement subtraction, a subtract-with-borrow primitive is required. When efficient platform-specific implementation isn't available (e.g. x86_64's _subborrow_u64 intrinsic), it needs to be implemented in Standard C++. I've been ab...

Q: C++20 Coroutine Task

rafooThis project is the natural extension to my attempt to make a templatedgenerator coroutine. This time, I tried what I called a "task" (may be not the real term for this) : it generates a value or not, and is recursively awaitable. It can call other coroutines which each pause will also pause the ...

@BittermanAndy But @PandaWood already told you you can use Directory.build.props which has more advantage than your solution because you don't have to modify every project to add this Shared.AssemblyInfo.cs file as link. You don't have to teach developers that they should add it when they create new project and check it on code review. It just works for all current and new projects automatically. How doing nothing is "harder" than having to remember to modify csproj. — Mariusz Pawelski 41 secs ago

I see it and, again, please see How to Ask. If you delete your answer, copy/paste the code from it into your question, and add concise, testable sample input and expected output then you will arguably have a valid question for this forum as then you'll at least have the required (and currently missing) minimal reproducible example though some people may tell you that you should post it on some kind of code review forum instead of here depending on how you phrase the text of your question. — Ed Morton 12 secs ago
