What is the most basic class in C++

Question

I hope this question is not too silly, but what is the most basic class in standard C++? object? Object?

class MyObject : public object{  ...

and I get "Expected class-name before token{"

Is there any map, diagram or image that shows standard c++ classes inheritance? Something like this but for C++ ?

Answer 1

There is no most basic class in C++ i.e. there is no common base class for all the classes.

Answer 2

There is no fundamental object type in C++, unlike in e.g. Java.
