You are creating a 'virtual pet' program. The pet object will have a number of attributes, representing the state of the pet. You will need to create some entity to represent attributes in general, and you will also need to create some specific attributes. You will then create a generic pet class (or interface) which has these specific attributes. Finally you will make at least one subclass of the pet class which will be a specific type of pet, and at least one instance of that class.
Attributes
An attribute is a characteristic of a pet. Each attribute is
essentially a list of values. For example, a hunger attribute may
have values from "famished" through "content" to "bloated." There
should be some way to check the value of the attribute, as well as
to increase and decrease the value. Note that you will be expected
to create some sort of abstract data type (ADT) to represent the
attribute. You are not yet building SPECIFIC attributes (like
hunger or happiness) but a type that represents the common
characteristics of all attributes. You might use an interface or an
abstract class to generate your abstraction, but plan it first as
an abstract data type.
Specific Attributes
Once you have created a generic attribute class, make some
subclasses to represent the specific attributes you want your pets
to have. If you designed the ADT well, creating specific subclasses
should be quite easy. The main method of the specific classes
should test the main functionality of the class.
Making your abstract pet
Now create a pet class that uses the attributes you have generated.
This class is also abstract, as it represents just a type of pet.
It will include attributes as data members, and it may also have
other characteristics. You may also add methods that indicate
actions the user can take with the pet, including things like feed
and play (which may affect attributes) and perhaps other activities
like rename (which might change another data member of the pet) and
sleep (which might indicate the passage of time.)
Build a specific pet class
Finally you should be able to build a specific type of pet (like a
lizard or a unicorn) that inherits from the pet class. This should
begin (of course) with characteristics derived from the abstract
pet, but you could then add new attributes or behaviors specific to
your type of pet.
The main method of this pet class should instantiate an instance of the pet and indicate all the things it can do.
Create an interface for interacting with the pet.
Build some type of tool for interacting with the pet. At minimum
this should allow the user to create a pet, interact with it in the
ways you have defined, save its current status for future play
(using object serialization) and load a previously saved pet.

Give reasonably brief, but complete answers to the following.
10. a) Suppose class Y is derived from class X. Each class declares
a constructor and a destructor. Class Y has a string member
object that has a constructor and destructor. In what order do
the three constructors and destructors run when instances of
class Y are created and destroyed?
b) Should X's destructor be declared virtual? Why or why not,
and what difference would it make?

virtual function? Give an example of a pure virtual function.
