Description
This is the most complex application that you have seen so far. It is comprised of six user defined types: four classes and two enums. This assignment attempts to simulate a simple version of a Theater application. In this application the user is able to search for a movie based on genre, name of actor, the time of the day and the day of the week.
You should define your types in the following order: the two enums, Time, Movie, Show and then Theater You will perform some simple queries on this collection.
The MovieDay Enum
This type represents the days of the week and is comprised of seven constants. The constants are the first three letters of the day of the week.
The MovieGenre Enum
This type represents the various categories of movie. Because a movie may fall under multiple categories, you will have to use the [Flags] to decorate this enum.
The bit-wise operator is used to combine more than one genre. E.g. MovieGenre genre = MovieGenre.Action | MovieGenre.Romance | MovieGenre.Comedy;
For this to work correctly, you will have to assign appropriate values for each name. Appropriate values are 0, 1, 2, 4, 8, 16, 32 etc.
The Time Class
This type represents the days of the week.
Time
Class
Properties
+ Hours {get; set;} : int
+ Minutes {get; set;}: int

3. Seconds – this property is an int representing the second. The getter is public and the setter is private.
Methods:
1. Time(int hours, int minutes, int seconds) – This public constructor takes three int parameters and assigns them to the appropriate properties
2. ToString() – This method overrides the same method of the Object class. It does not take any parameter but return a string representation of itself. You decide on the format for the output.
The Movie Class
