Example-2A) Create a super (parent) class called Course. The Course class represents any course thatdoes not have a lab (without a lab). The class should include the followings:*Private attributes:o courseCode (type string)o examMark (type double)O courseWorkMark (type double)"A constructor that initializes the three attributes of the class.*A public and static variable called noOfCourses (stands for number of courses). Theinitial value for this variable is 0 and it increases with every new course object created.A public method called finalMark () which returns the total sum of course' marks. Thetotal mark is computed as (examMark + courseWorkMark)."A public and static method called getNoOfCourses(). it returns the total number ofcourses created.•An overriden method called toString(), which returns a string that represents the Courseobject.fppt.comExample-2B) Extend the above Course code by creating a sub (child) class called CourseLab.The CourseLab inherits the super class Course. The class should include the followings:*An attribute called labMark (type double), which represents the mark of the lab.•A constructor that initializes the attributes of the class. (Hint: don't forget to consider thesuper class' constructor using the keyword: super).*An overriden method called finalMark (), which returns the total sum of course' marks inthis sub class. The total mark in this case is computed as (examMark + course WorkMark +labMark)."An overriden method called toString(), which returns a string that represents theCourseLab object.C) Write an application with a main Method that creates objects from the classes Course andCourseLab and displays the objects information. Your application code should also displaythe total number of courses that have been created.

Which statement of the following is the most appropriate? Group of answer choices When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the botttom of the implementation file for easy reference.

Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result
C++ Assignment---This is an unfinished code please complete it. Make changes if necessary. Upvote for finished working code. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do…
Create a class of type student .Members will include: name, gpa, rank (year) Make sure all data is private and all functions are public. Write member functions to:Set or initialize the dataRetrieve the data (get’em and set’em )Announce names of students who are eligible for a scholarship (those who have a GPA of 3.0 or higher)The program will declare at least two objects (pupils) of your new class and test each of the functions (OR if you would like to try your hand at vectors, create them dynamically- this may require a little research/review on your part).

6. Patient Charges Write a class named Patient that has attributes for the following data: • First name, middle name, and last name • Address, city, state, and ZIP code • Phone number ● The Patient class's init__ method should accept an argument for each attribute. The Name and phone number of emergency contact Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: • Name of the procedure • Date of the procedure • Name of the practitioner who performed the procedure • Charges for the procedure 107 The Procedure class's __init__ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three…
Double Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…
