But the file can't contain more than 100 movies. Then, it should offer the user a menu with the following options: Display movies sorted by id Display movies sorted by release date, then rating Lookup a release date given a name Lookup a movie by id Quit the Program The program should perform the selected operation and then re-display the menu.
