I would say for lower level code, when C++ is used, it's a C-like dialect of C++ that is used. This is even true with something like clang and llvm. Certainly

I would say for lower level code, when C++ is used, it's a C-like dialect of C++ that is used. This is even true with something like clang and llvm. Certainly the /more/ low level you go, the less C++-isms you see. These days, sure you can use a highly restricted form of C++ in systems close to HW, but you might as well be using the industry standard in those environments, which is C, compiled with a C/C++ compiler.
