You can write C style code in C++ and still get access to features that are still interesting in the problem domain. constexpr functions, typesafe enums, static assertions, and destructors come to mind. No need to even touch a template or inheritance if you don't want to. The main benefits of C per se are ABI stability and availability of compilers.
