When designing a class hierarchy, which of the following should be true of a superclass?

• A superclass should contain the data and functionality that are common to all subclasses that inherit from the superclass.

• A superclass should be the largest, most complex class from which all other subclasses are derived.

• A superclass should contain the data and functionality that are only required for the most complex class.

• A superclass should have public data in order to provide access for the entire class hierarchy.

• A superclass should contain the most specific details of the class hierarchy.

When designing classes, which of the following would be the best reason to use inheritance?

• Inheritance allows you to write applications that require fewer base and super classes.

• Inheritance allows the creation of a subclass that can use the methods of its superclass without rewriting the code for those methods.

• Inheritance allows for data encapsulation, while noninherited classes do not allow for data encapsulation.

• Inheritance reduces the number of polymorphic structures encapsulated in applications.

• Inheritance guarantees that the applications will compile and execute much more quickly.
