Even when C++ was created, object-orientation was not a goal, but rather a means to an end. Yes, that was a significant feature, and the original name was "C with objects", but even then it was only part of the bigger picture, and that part got smaller over time. The next big step away from an OO-orientation of the language (no, that's not a typo) was when the STL was adopted into the standard library - with its iterators and templated mini-algorithms. At that point it could certainly be said already that C++ is a multi-paradigmatic language, and that's become even more true over time.

You could definitely (?) implement a Java-like container framework, with class like Iterable<char> or IEnumerable<char> and almsot every OO bell and whistle - if you wanted to. But it would not be very useful.
