Yes, C++ is not an "object-oriented language" and never was. The OO features were added because at the time it was the raging fad and people thought that every language simply must have "OOP". But "OOP" was never a foundational principle for C++, more like a tacked-on sidecar.

You're arguing that a language that arose specifically to add classes to C was not meant to be object-oriented? I'd be interested in seeing that argument fleshed out in more detail.

  It is true that subsequent c++ evolution de-emphasised OOP, but you are completely right that the original selling point of C++ over C definitely was (Simula style) OOP.

    Three points: a) 'Simula style' isn't at all like the Smalltalk-derived programming patterns we call 'OOP'. (Simula was about actor-oriented programming anyways, hence the name.) b) The unique differentiator for C++ was the STL, and not the OOP features that were done better and cleaner in other languages. c) The killer feature for early C++ adoption was operator overloading, not inheritance. (Pretty much nobody liked using inheritance in C++ even back in the day.)

Nothing about the name "Simula" suggests actors. > The unique differentiator for C++ was the STL https://en.wikipedia.org/wiki/C%2B%2B#History https://en.wikipedia.org/wiki/C%2B%2B#History isn't very clear, but it seems to suggest that templates weren't added to C++ until 1990 or later. The STL came around 1993, eleven years after the development of C++ started, not even counting its previous life as C with Classes. Surely in those eleven years people found other differentiators that kept up interest?

Don't bother responding, the answer is that it's nothing more than your fantasizing.

      Simula and Smalltalk were the two original OO languages. C++ firmly takes its OO capabilities from Simula (the virtual keyword literally comes from there with the same semantics), and is quite distinct from the OO flavour of Smalltalk. Objective-C, with its selector based late binding for example, is clearly Smalltalk inspired.

  Its original name was actually "C with Classes".
