Expert Solution & Answer

Program Plan Intro

Inheritance:

Inheritance is the concept of acquiring the base class properties to the derived class. The term base class is referred to as general class and the derived class is the specialized class.

  • It increases the functionality of the derived class.
  • It also promotes the reusability of code (of the base class).

Explanation of Solution

“is a” relationship:

In object oriented programming, the “is-a” relationship is based on inheritance. When one object has a specialized version of another object, then there exists an “is-a” relationship between the two objects.

  • When an “is-a” relationship occurs between two classes, which means that the derived class acquires all the properties of the base class. 
  • The derived class inherit the member function and member variables from the base class.

Example of “is-a” relationship:

  • Parrot “is-a” bird.
  • Circle “is-a” shape.
  • Rose “is-a” flower.

8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods: A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase. When the user is ready to check out, the…
5. RetailItem ClassWrite a class named RetailItem that holds data about an item in a retail store. The class should store the following data in attributes: item description, units in inventory, and price. Once you have written the class, write a program that creates three RetailItem objects and stores the following data in them: Description    Units in Inventory    PriceItem #1    Jacket    12    59.95Item #2    Designer Jeans    40    34.95Item #3    Shirt    20    24.95
Find the Error: class Information:     def __init__(self, name, address, age, phone_number):         self.__name = name         self.__address = address         self.__age = age         self.__phone_number = phone_number   def main():     my_info = Information('John Doe','111 My Street', \                                '555-555-1281')
