    It has no type. It’s an implementation detail unspecified by the standard; it is not part of the language.

    Note that C++ doesn’t say that there has to be a virtual table or a virtual “pointer” at all (though this is the most common implementation of RTTI in C++ toolchains).

    Also, your analysis is wrong. In, say, GCC, usually each object gets a vptr that points to the relevant virtual table for that object’s type: object has pointer, type has table.
