vptr

[Rahul]

Hi Everyone,

I was wondering what is the datatype of vtpr and what is its access
specifier (public or private or protected)?
This is in regard to the inheritance of a class having one or more
virtual functions.

Thanks in advance!!!

It is all implementation specific, so we don't know.

There is not even a requirement to have a vptr, if the compiler can
perform the required actions without one.

I think as a user there is no need to know the type,

I think that as a user there is no way to tell if there is a vptr to
begin with.
