Question
Description
(50 points) Code a TicTacToe class for the forth game in Homework 12, that allows the computer plays a 3 by 3 Tic Tac Toe game against a human player. This game displays the lines and the position of the Tic Tac Toe game and prompts the player to choose a move. The move is recorded on the screen and the computer picks his move from those that are left. The player then picks his next move. The program should allow only legal moves. The program should indicate when there is a winner and tell who won. The player is then asked if he would like to play again. If the game is played the second time the computer is first to move. The player and computer (making random but valid move) take turns being first. Your program should duplicate the output found in the Sample Output From a Test Run below.
Extra Credits Opportunities:
Extra credit (20 points): Code a TicTacToeExpendable class in such way that a player is allowed to decide the dimension of the game board (3 or above) by entering an integer number. Then the game starts on a game board on the desired dimension.
Extra credit (30 points): Code a TicTacToeSmart class so the computer plays a 3 X 3 Tie Tac Toe game to win. When it is the computer’s move the first thing to determine is if there is a move that will win the game. If the computer does not have a winning move then determine if a computer move will block the human from winning. Code some methods to make the computer smart to win.
Extra credit (50 points): Code a TicTacToeSmartExpend class so the computer plays Tic Tac Toe game on a expendable game board against a human player to win.
Here are some Tic tac toe design considerations:
Understand two-dimensional arrays.
Play the game using a three by three char type array.
___ ___ ___
|___|___|___|
|___|___|___|
|___|___|___|
Know the index locations of the characters X and O when they are placed.
An X or O can be placed on the game board by assigning the character X or O to the proper position
Design the game at a high level. Each level is then broken down further (by defining more methods; mostly private). High level might look like this
While there is not a winner and the count of moves is less than 9
Add one to the number of moves
If it is my turn then I choose a move
Else the computer chooses a move
If there are 9 moves then the game is over.
If there is not a winner it is a “cats” game.
Suggestion of methods:
A method that introduces the game rules.
A method shows the game board position numbers.
A method checks if a move is legal. i.e. only within 1 through 6 and if the position is not already occupied.
A method to make a mark on the game board
A method to display the game board
A method to "clean" the game board to start anew.
Check if the current board has a winnerA method for player to make a move
horizontally
vertically
diagonally (from upper left to lower right or from upper right to lower left)
A method for computer to make a move (randomly or intelligently).
A method for a human player to make a move.

Sample Interactions and Output From a Test Run of the Tic Tac Toe Game
3 by 3 Tic Tac Toe Game
I am very happy to play this game with you. When we play, you will be the X and I will be the O
We'll take turns to pick moves; one at a time, and take turn to start. I'll let you start first in
the first game. To pick a move, simply enter an integer number between 1 and 9 inclusive
starting from 1 on top row, left to right, continued to the next row, from left to right again,
and so on. Natually, it's invalid to pick a spot already taken by any of the previous moves.
Whoever gets 3 in a row, either horizontally, dianglelly or vertically first, wins the game.
May the best player wins.

(50 points) After successfully creating the Tic Tac Toe game, integrates all games (Die Game, Guess Game and Tic Tac Toe Game) into your Menu class so that when a user selects one of the three games from the menu, the corresponding game will start. Since we only have three games at this time, remember to modify your Menu class to show only four options (three game choices and the Exit option to end the program).
