Modern C++ kind of.

Gang of four book was written with Smalltalk and C++ examples.

Back in the 90's we had Mac OS PowerPlant, CSet++ on OS/2, OWL/VCL/MFC/ATL on Windows, Motif++ on UNIX, Telligent, and a myriad of ORM, distributed computing, image libraries and what not written in OOP C++.

Then came Java, took the best practices out from OOP C++, and two decades later 90's C++ is known as Java OOP and people act as if C++ OOP never happened.

Maybe now it is, but before STL etc. were thought of, C++ was intended by its creator to bring better support for OOP to C.
