Program Plan Intro
Class Object:
- A class is a collection of data members and member functions, which are used to represent the overall structure of the project.
- The objects are created to access the data members and member functions of the class.
- Public member functions are accessed by using “.” dot operator.

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…
Book Donation App
Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes:
1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions:
• getDonor(donorId): returns a donor by id.
• addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number.
• updateDonor(donor): updates the donor having the matching donorID.
• deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books.
2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties.
• donorID references the book’s donor. This…
1. Employee Class
Write a class named Employee that has the following fields:
• name. The name field references a String object that holds the employee's name.
• idNumber. The idNumber is an int variable that holds the employee's ID number
• department. The department field references a String object that holds the no
of the department where the employee works.
• position. The position field references a String object that holds the employee's
job title.
The class should have the following constructors:
• A constructor that accepts the following values as arguments and assigns them to the
appropriate fields: employee's name, employee's ID number, department, and
position.
• A constructor that accepts the following values as arguments and assigns them to the
appropriate fields: employee's name and ID number. The department and position
fields should be assigned an empty string ("").
• A no-arg constructor that assigns empty strings ("") to the name, department, and
position fields, and…
