How to write C++ program that contains two arrays called actors and roles, each of size N. For each i, actors[i] is the name of an actor and roles[i] is a multiset of strings that contains the names of the movies that the actor has appeared in. The program reads the initial information for these arrays from files in a format that you design. Once the program is running, the user can type in the name of an actor and receive a list of all the movies for that actor. Or the user may type the name of a movie and receive a list of all the actors in that movie ?
