Answer the following statements true (T) or false (F)

Question

1. An inheritance chain of any desired length is possible.
2. The class D inherits from base class B using public inheritance. The class B has public member function f(), but the derived class has no function member with this signature. The f() is not available to an object of class D.
3. Deriving a class from a base class requires serious changes to the base class.
4. We can assign a base class object to a derived class variable.

Answer 1

1. True
There is no reason to limit the length of an inheritance chain. There are software complexity arguments against very long inheritance chains that are beyond the scope of this text.
2. False
The derived class D inherits public members from class D.
3. False
No changes are needed to derive one class from another.
4. False
Where would the parts of the derived class object that are not in the base class variable go? Once this issue is raised, you should realize this false by now, although this is not formally discussed until the next chapter. The difficulty is called the ‘slicing problem.”
