That's a good point. But then you're not benchmarking C++ as a distinct language. So what would sufficiently distinguish a C++ program from a C program? Let's assume it's not just minor incompatibilities introduced to prevent compilation by a C compiler.

There must have used some definition that is not explicit in the paper, but you can see in this code sample that the author used various C++ standard data types (std::string, std::array), iterators, classes, concurrency (std::thread). I'm no judge of C++ style, but perhaps it's "C++ as a C++ developer circa 1997 would have written it".
