No, there's OO C, low-level C, GLib C, etc. There's Android Java, Enterprise Java, Standard Java. Any language catering to different customers will have various styles. There are two big C++ coding styles: C with classes, an old style which has little use nowadays and modern C++, the recommended way, used in new projects. Asking "what is the idiomatic style in C++?" must be a rhetorical question, because it's obviously modern C++, the leaders of the C++ community have made this clear repeatedly. Template metaprogramming is a technique, not a programming style. OP should do more hacking without fear and less spreading FUD.
