You have been asked to develop a data model for TV Guide. Consider the following business rules: • There are many channels on TV

• Each channel broadcasts many shows.

• Some shows are broadcast multiple times over the course of a week. (i. e. Showtime might show The Tudors Sundays at 10:00 PM and Tuesday at 9:00 PM)

• A show will have multiple actors

• An actor has a specific role in each show and can be in multiple shows (i. e. Chris Noth is Mike on Law & Order and Mr. Big on Sex and the City)

Task

Your task is to study the business objectives and model the data and relationships to support these objectives. You must create an Entity-Relationship Model. This should be a high-level model, meaning, unless necessary for understanding, you do not need to specify additional attributes for your entities and relationships other than ones described or implied above. You do need to identify all entities, relationships, attributes and cardinalities according to the description above. These specifications might not be as clear or as formally defined as might be needed, but you are the data modeler, you can see through this, and when you can't, you write your assumptions and proceed anyway. Again, if you need to make assumptions, ensure you document them at the bottom of your diagram.

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).
