Pet Class
Design a class named Pet, which should have the following fields:
- name. The name field holds the name of a pet.
- type. The type field holds the type of animal that a pot is. Example values are “Dog”, “Cat”, and “Bird”.
- age. The age field holds the pet’s age.
The Pet class should also have the following methods:
- setName. The setName method stores a value in the name field.
- setType. The setType method stores a value in the type field.
- setAge. The setAge method stores a value in the age field.
- getName. The getName method returns the value of the name field.
- gettype. The getType method returns the value of the type field.
- getAge. The getAge method returns the value of the age field.

name: The name field holds the name of a pet.
type: The type field holds the type of animal that a pet is. Example values are "Dog", "Cat", and "Bird".
age: The age field holds the pet’s age.
The Pet class should also have the following methods:

setAge: The setAge method stores a value in the age
getName: The getName method returns the value of the name
getType: The getType method returns the value of the type
getAge: The getAge method returns the value of the age
Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object’s accessor methods to retrieve the pet’s name, type, and age and display this data on the screen.

(Invoice Class) Create a class called Invoice that a hardware store might use to representan invoice for an item sold at the store. An Invoice should include four data members—a part number (type string), a part description (type string), a quantity of the item being purchased (typeint) and a price per item (type int). Your class should have a constructor that initializes the fourdata members. A constructor that receives multiple arguments is defined with the form:ClassName( TypeName1 parameterName1, TypeName2 parameterName2, ... )Provide a set and a get function for each data member. In addition, provide a member functionnamed getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by theprice per item), then returns the amount as an int value. If the quantity is not positive, it should beset to 0. If the price per item is not positive, it should be set to 0. Write a test program that demonstrates class Invoice’s capabilities
