I consider myself an expert on C and I always used to put C/C++ on my resume. But it occurs to my that C and C++ aren’t really similar anymore and that I don’t really know C++ at this point. I’ve always despised C++ but that’s when it was pretty similar to C. It seems to have gotten exponentially more complicated but also it seems like it’s pretty expressive at this point: potentially supporting Rust-like safety and FP-like design. Maybe someone who’s an expert can tell me how different C++20 is from C?
