but this post is about c++ 23 and probably should stay on that topic? Everyone who uses c knows you can do it in c++ but either don't want to introduce the extra complexities, work with older code bases, prefer the "simplicity" of c, or have an organizational requirement. Personally on embedded I like c++, especially raii, smart pointers, containers, and classes, but I completely avoid rtti, exceptions, and complex template metaprogramming (by me). That subset is easy to keep in my head and on my projects. However some clients want C, and that's what I give them.
