The Painting Subclass
Write class as follows:
The class is named Painting, and it inherits from the Art class.
It has a private String member variable named medium
It has a default constructor that assigns the values "No name" to name, "No artist" to artist, -1 to year, and "No medium" to the medium variable. This default constructor calls the four-argument constructor.
It has a four-argument constructor to assign values to the name, artist, year, and medium variables.
It has a getter and settersfor the medium variable.
It has a toString() method
This class contains no other methods
Make sure to include your name, the name of this class, our course number, and the Activity number in a Javadoc comment at the top.
Make sure to write a Javadoc comment for each of these methods.

Private Member Functions
The member functions declared private, isLeap, daysPerMonth, name, number, are helperfunctions - member functions that will never be needed by a user of the class, and so do not belong to the public interface (which is why they are "private"). They are, however, needed by the interface functions (public member functions), which use them to test the validity of arguments and construct valid dates. For example, the constructor that passes in the month as a string will call the number function to assign a value to the unsigned member variable month.
isLeap: The rule for whether a year is a leap year is:
(year % 4 == 0) implies leap year
except (year % 100 == 0) implies NOT leap year
except (year % 400 == 0) implies leap year
So, for instance, year 2000 is a leap year, but 1900 is NOT a leap year. Years…

- Question Object Oriented Programming c++ Write a program that defines a class with a data member to holds a "serial number" for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you'll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.arrow_forwardWrite in C++ Language. (Employee Record): Create a class named 'Staff' having the following members: Data members - Id – Name - Phone number – Address - AgeIt also has a function named 'printSalary' which prints the salary of the staff.Two classes 'Employee' and 'Officer' inherits the 'Staff' class. The 'Employee' and 'Officer' classes have data members 'Top Skill' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a officer by making an object of both of these classes and print the same.arrow_forwardC++ please Write a driver function definition called add that takes as its parameters two FractionType objects.
