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…

C++ Programming Assignment 6 Dynamic Pets The objective of this lab is to demonstrate dynamic allocation and deallocation of memory. Instructions: Write a class called Pet that contains an animal’s name, type, and weight. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new pet”. The destructor should print out the following message: “In the Pet destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of pets in his or her household. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Pet objects. Construct a loop in main() that executes once for each of the number of pets that the user indicated. Within this loop, ask the user to enter the name and type of pet. Using a random number generator, generate a weight between 1-100 pounds. Seed this random number generator with 100.…

Programming Language= PYTHON 1. Pet Class Write a class named Pet, which should have the following data attributes: • _ _name (for the name of a pet) • _ _animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’) • _ _age (for the pet’s age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: • set_name This method assigns a value to the _ _name field. • set_animal_type This method assigns a value to the _ _animal_type field. • set_age This method assigns a value to the _ _age field. • get_name This method returns the value of the _ _ name field. • get_animal_type This method returns the value of the _ _animal_type field. • get_age This method returns the value of the _ _age field. Once you have written the class, write 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.

Chapter 15 Customer Employee Creator Create an object-oriented program that allows you to enter data for customers and employees. Each class will be stored in its own python file. Console Specifications Create a Person class that provides attributes for first name, last name, and email address. Include a parameter for each attribute in the constructor method. This class will provide a property or method that returns the person’s full name. Create a Customer class that inherits the Person class. This class must add an attribute for a customer Create an Employee class that inherits the Person class. This class must add an attribute for a social security number (SSN). Put the above three classes in a module named ‘company_objects’, separate from the application module. The program will create a Customer or Employee object from the data entered by the user and store the object in a single variable. Create a function that will display the Customer or Employee. The function will have a…
