  In `DerivedClass1`, the member function `PublicFunc` is a public member and `ProtectedFunc` is a protected member because `BaseClass` is a public base class. `PrivateFunc` is private to `BaseClass`, and it is inaccessible to any derived classes.

  In the figure, a name declared in class `VBase` is always reached through class `RightPath`. The right path is more accessible because `RightPath` declares `VBase` as a public base class, whereas `LeftPath` declares `VBase` as private.
