Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four data members a part number (type string), a part description (type string), a quantity of the item being purchased (type int) and a price per item (type int). Your class should have a constructor that initializes the four data members. Provide a set and a get function for each data member. In addition, provide a member function named getlnvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0. Write a test program that demonstrates class Invoice's capabilities.

Create a class called Bill that a hardware store might use to represent a bill for an item sold at the store. A Bill should include three data members—a part number (type string), a quantity of the item being purchased (type int) and a price per item (type double). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. In addition, provide a member function named getBillAmount that calculates the bill amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0. Write a C++ test program that demonstrates class Bill’s capabilities.
There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.
User-defined Class: You will design and implement your own data class. The class will store data that has been read as user input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named MoneyChange. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 6 instance variables to represent amounts for each of the 6 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide a legitimate justification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriate get and set methods for…
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…
Write a program to create a class teacher with the following data members.ID: Can be accessed only from the teacher class and derived classes of the teacher.Age: Can be accessed from all the classes and packages in the application.Phone Number: Can be accessed only from the classes inside the same package.Write the constructor function. Derive a class Math_teacher from the teacher class, add the following two data members in the Math_teacher class.Room Number: This can be accessed by all the classes in the application.Course_ID: This can be accessed by all the classes in the same package.Write the constructor function.
C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().
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…
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…
