Suppose you are working for a Zoo and you are asked to write the class for keeping information about animals. You decide to call your class as Animal.

• Write a class to represent a Animal.
• The attributes are: the animal id, the species, price, and a flag indicating whether it is currently being in a show.
  • Note that, when an animal is created, a unique new id number is allocated toid. This id number will be generated by adding one to the previously usedidnumber, which is kept stored in a variable shared by all Animal objects.
• Include accessors for all attributes, a mutator to change the flag, and a method to increase the price.
• Two most necessary constructors (that will be used create new animal(s));
