Chapter 10, Problem 11PP
Consider a class Movie that contains information about a movie. The class has the following attributes:
■ The movie name
■ The MPAA rating (for example, G, PG, PG-13, R)
■ The number of people that have rated this movie as a 1 (Terrible)
■ The number of people that have rated this movie as a 2 (Bad)
■ The number of people that have rated this movie as a 3 (OK)
■ The number of people that have rated this movie as a 4 (Good)
■ The number of people that have rated this movie as a 5 (Great)
Implement the class with accessor and mutator functions for the movie name and MPAA rating. Write a function addRating that takes an integer as an input parameter. The function should verify that the parameter is a number between 1 and 5, and if so, increment the number of people rating the movie that match the input parameter. For example, if 3 is the input parameter, then the number of people that rated the movie as a 3 should be incremented by 1. Write another function, getAverage, that returns the average value for all of the movie ratings. Finally, add a constructor that allows the programmer to create the object with a specified name and MPAA rating. The number of people rating the movie should be set to 0 in the constructor.
Test the class by writing a main function that creates at least two movie objects, adds at least five ratings for each movie, and outputs the movie name, MPAA rating, and average rating for each movie object.

Consider the class Movie that contains information about a movie. The class has
the following attributes:
. The movie name
• The SA Film and Publication Board (FPB) rating (for example, A, PG, 7-9 PG,
10-12 PG, 13, 16, 18, X18, XX) 1
• The number of people that have rated this movie as 1 (Terrible)
• The

people that have rated this
movie as 3 (OK)

number of people that have rated this movie as 4 (Good)
people that have rated this movie as 5 (Great)
The class Movie you created, can be implemented more efficiently
if we use an array instead of 5 different member variables to count the number
of people rating a movie at a specific score. Adjust your class Movie to use an
array to count the score ratings for a movie, and test it with the same main
function.
Create a class Person to represent a person according to the following requirements: A person has two attributes:
id
Add a constructer to initialize all the attributes to specific values.
Add all setter and getter methods.
Create a class Product to represent a product according to the following requirements:
A product has four attributes:
a reference number (can’t be changed)
a price
an owner (is a person)
a shopName (is the same for all the products).
Add a constructer without parameters to initialize all the attributes to default values (0 for numbers, "" for a string and null for object).
Add a second constructer to initialize all the attributes to specific values. Use the keyword "this".
Add the method changePrice that change the price of a product. The method must display an error message if the given price is negative.
Add a static method changeShopName to change the shop name.
Add all the getter methods. The method getOwner must return an owner.
