Need to modify a c++ assignment

Assignment 5

I will provide the orginial homework

Modify Assignment 4, changing:

1. The movies array to one of three (3) types:
   1. A pointer to a dynamically allocated array of movies (Movie * movies). Use an arbitrary initial size of 1000.
   2. A static array of movie pointers (Movie * movies[1000]).
   3. A pointer to a dynamically allocated array of movie pointers (Movie ** movies - a typedef might be good here). Use an arbitrary initial size of 1000.
2. Allow the user to enter a movie search string or a movie number (account for the movie not being found by either criteria).
3. Replace the rank/box array index with an enumerated type (no 0, 1, 2).
4. Resize the movies array to drop unused array elements if using options 1a or 1c.
5. Use a movie pointer (Movie * [or typedef]) as the parameter/return type for any methods accepting/returning a movie object.
6. Add const to all methods and return types as appropriate.
   If a method does not modify a data member, then const is appropriate.
   As movies are not modified after having been created/loaded, all Movie parameters and return types should probably be const Movie *.
7. Add a destructor and delete/delete[ ] as appropriate to eliminate any memory leaks.
   Also set pointers to null as/if needed.

• Modify the driver to enable retrieval of the next movie, that is, the movie after the one currently shown, without the user entering, or knowing, the movie number.
• Again, this could be as simple as specifying a special character to indicate retrieval of the next movie.
• How to handle retrieving the next movie at startup (or after displaying the last movie, or after requesting an invalid movie), is a design decision.
  Possible options are to show the first movie or treat it as undefined (movie not found).
