Program1Notes

PROG1
	will have multiple classes
		text
		Movie
		movies
	read program one grade sheet
	comment above functions

	Text class //class has two private attributes
		const char* textArray //dynamically allocated
		int textLength
	Movie class //this is all one movie object. holds a public interface (public functions)
		Text* movieTitle //text* indicates it will point to the text class. receiving information from the text class
		Text* movieGenre
		int movieLength
		Text* movieRating
		int movieOscars = somenumber
		float movieStars = somenumber
		int movieYear = somenumber
	Movies class //has 3 attributes
		int maxMovies //how many movies can be held in the library
		int numMovies //how many are currently owned
		Movie** movieLibrary //two stars indicating the var is a pointer pointing to an array of pointers.
							 //points to movie class most likely
	a driver will allow the user to add, edit, delete, print etc movies in their library
