What's a paradigm? It's a way of viewing things. What ways are there of viewing programming? Well, there's functional, there's structured, there's object-oriented, there's generic, and maybe some more.
Can C++ be used to write non-object-oriented, non-functional, purely structured-programming-style procedural code? Yes, it can. (Essentially, that's the subset that's in common between C and C++.) Can it be used to write object-oriented code? Certainly. Can it be used to write functional code? Again, yes (though not nearly as purely as the Haskell zealots would like - but C++ doesn't enforce the purity the way Haskell does precisely because C++ is multi-paradigm). Can C++ be used to write generic code? Yes. (I have heard that the STL was written in C++ because, at the time, it was the only widely used language that would do what Stepanov wanted to be able to do.)
Four different paradigms. You can write C++ code using any of them, or you can mix and match. That's multi-paradigm.
Or are you arguing that, if you have more than one paradigm, you don't have any? That might be true of a program, though I think that the argument is merely a matter of definition, and therefore not very interesting. But if the language makes it easy to write in several paradigms, it seems perfectly appropriate to call it multi-paradigm.
False.
