C++ can, fair. Still there is a huge amount of developers sticking to plain C, even if they can use C++ (FFmpeg, VLC, Linux, etc.), why do they do that? I think

C++ can, fair. Still there is a huge amount of developers sticking to plain C, even if they can use C++ (FFmpeg, VLC, Linux, etc.), why do they do that? I think an answer to this question would be pretty much the answer for the initial question. There might be cultural, historical, and other reasons for it. The thing with Zig is that, if I understand it correctly, Zig can't be interleaved with other C code in the same file, which forces you to separate things, loosing convenience. On the other hand, to use Datatype99, you can just #include <datatype99.h> and you're ready to go.
