- Design and code a class in C++ that represents a single month of the year. It should have a single integer-typed data member to represent the month. Make sure to provide proper construction, access, and mutation for this member as well as input and output methods. In addition, methods for comparing two months chronologically for ordering would be useful as would a method to advance to the next month (note that January follows December and begins the cycle anew) or previous month. In fact, thinking about it, it might be good to be able to advance to a month an arbitrary number of whole months in the future or past: January '+' 5 = June; March '-' 5 = October. Place your Month class in a library. Write a test application (driver) for your class. Oh, and the programmers who commissioned this class wanted to make sure it could handle not only integer-valued representation of a Month but also either whole-word names or three-letter abbreviations for the Months. That means that they should…Declaring a function that is not a member of a class C as a(n) to C allows that function to access all of C's private and protected members.Explain the following and their use.PolymorphismInheritancePointersAbstract Data Types

Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.Justify why it is desirable to have accessors to private types rather than making the types public for the following three reasons.Interpreted of sub code bellow is: point operator * (point v2) { int x1, y1: x1 = x * v2.x; y1 = y * v2.y; point product = point(x1, y1): return product: }}: o return type of binary operator function is point no return type of binary operator function in point class return type of binary operator function is point in point class return type of operator function is point in point class

- Write a C++ program which will perform the following operations: • Define a class with name Car and has the following members o Four private data members (Name, Model, Color and Price). . Define a constructor function (private member) which displays a text message whenever a new object is created successfully. . Define a destructor function (private member) which displays a text message whenever an object is deleted. o Define a method (public) which gets the data elements from user. . Define a method(public) which displays the data elements to user. o Create the objects of class Car and invoke its methods.Write a C++ program that: Implements a class with three data members {sum (int), count (int), avg (float)}. Implement the following 3 member functions: The first function is a default constructor which initializes sum and count to zero. The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. • The third function is named output which divides the sum over count and save it to avg then print the avg value). Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbersUsing the scenario of Object oriented programming Q1 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.
