LWe've all "liked" someting or the other haven't we? Well, in this task you need to create the behind the scenes "like" functionality for this program. A user needs to be able to watch a film, and then decide whether to like it or not. The option is presented after the film has been viewed of course! You won't be able to click this like in the same way you do on facebook, so use your imagination a little. You could, for instance, prompt the user to type "l", if they want to "like the film", or simply quit the program if they hated every second of it! Oh, and the likes need to be stored. Why? Because FAKEFLIX wants to know or may want to know what films are popular and which ones they ought to get rid of. This also makes for some interesting discussion. Where should you store the likes? In which file? Again, there is no wrong or right answer. Have a think and have a go. Our solution stores the "likes" in the films file, as per the origianl structure which allows for likes. Each time any user likes a film, the likes are incremented (go up by one) on that particular film's record. It's stored, and the next time the films are displayed you can see the likes
Note the field "likes" - this is where the likes will be stored for each film
0,Genre, Title, Rating, Likes 1,Sci-Fi,Out of the Silent Planet, PG, 0 2,Sci-Fi,Solaris, PG,0 3,Sci-Fi,Star Trek, PG, 0 4,Sci-Fi,Cosmos, PG, 0 5,Drama, The English Patient, 15, 0 6,Drama, Benhur, PG, 0 7,Drama, The Pursuit of Happiness, 12, 0 8,Drama, The Thin Red Line, 18, 0 9,Romance, When Harry met Sally, 12, 0 10,Romance, You've got mail, 12, 0 11,Romance, Last Tango in Paris, 18, 0 12,Romance, Casablanca, 12, 0
Note: See if you can do better (and you should be able to). The solutions provided are basic, and allow for discussion on possible alternative methods and solutions.
