You need to provide a report that shows: (10)
1. Your class designs
2. The algorithms used adding/deleting movies and reviews
a. This should be in pseudo-code or flowcharts, not just the code you
ended up writing
3. Compiling instructions
4. Sample runs (screenshots are fine)

Part1a: A Rating Class (5)
1. Design a class, Rating, to hold the rating information.
a. Private:
i. Should have at least: rating (int), comment (string)
b. Public:

ii. Setters to set the data
iii. Method to print the objecti
2. Test these to make sure this works.
Part1b: A RatingList Class (20)
1. Design a class, RatingList, which implements a single-link linked list of
Ratings.
a. A RatingNode struct
i. Private:
1. rating (Rating), *next (RatingNode)
b. Private:
i. Should have at least: *front (RatingNode)
c. Public:
i. Constructor(s)/Destructor
ii. addRating(Rating &r) method
1. adds the Rating r at the end of the list
iii. deleteRating(Rating &r)
1. finds and deletes the rating r from the list

2. Test to make sure this works

Part 2a: A RTime Class (5)
1. Design a class, RTime, to hold time information. This will be used to hold the
running time of a movie.
a. Private:
i. Should have at least: hours (int), minutes (int)
b. Public:
i. Constructor(s)/Destructor as needed
ii. Setters to set the data
iii. Method to print the objecti
2. Test this to make sure this works.
Part 2b: A Movie Class (10)
1. Design a class, Movie, to hold movie information.
a. Private:
i. Should have at least: title (string), runtime (RTime), *ratings
(RatingsList)
b. Public:
i. Constructor(s)/Destructor as needed
ii. Setters to set the data
iii. addRating(Rating &r) method to add a rating
iv. deleteRating(Rating &r) method to delete a rating
v. deleteAllRatings() method to delete all ratings
vi. compare(Movie *m) compare current with m, -1=less than,
0=equal. 1=greater than
vii. Method to print the objecti
2. Test this to make sure this works.
Part2c: A MovieList Class (35)
1. Design a class, MovieList, which implements a single-link linked list of Movies
sorted by title.
a. A MovieNode struct
i. Private:
1. *movie (Movie), *next (MovieNode)
b. Private:
i. Should have at least: *front (MovieNode)
c. Public:
i. Constructor(s)/Destructor
ii. addMovie(Movie *m) adds a movie to the list sorted by title
iii. removeMovie(string t) removes movie with title t
iv. deleteAllMovies() removes all movies
