1. Suppose a zoo wants a C++ program to keep track of its animals
and to provide information for visitors. Suppose the following
class is the base class of an public inheritance hierarchy.
class Animal
{
public:
Animal( std::string &);
private:
std::string name; // The particular animal’s name
};
Animal::Animal( std::string & animaName) : name(
animalName) {}
Create a derived class that represents a specific group or family
of animals, and derive from that another class that represents an
even more specific family or an individual species. For
example, your classes could be
Bear
and
PolarBear
, or
Cat
and
Lion
. Each of your classes should publicly inherit from the next
larger class up the inheritance chain (e.g.
PolarBear
inherits from
Bear
and
Bear
inherits from
Animal.
) Each of your classes should contain a private

2. static
data member representing something that is true of all objects
of that class. (e.g. for
PolarBear
, it might be a Boolean
isWhite).
Post the C++ declaration of your two classes and show the
constructor code and the initialization of the static data
members.
