Exercise

Chapter 20 shows a sample screen shot of Tic Tac Toe.

Write an actual working program of Tic Tac Toe.  You (a human) will be one player and the computer will be one player.

Write the program with intelligence so that the computer player should always either win or at least result in a tie (also known as a "cat").  A good Tic Tac Toe player will never lose!

Keep track of the scores for both the human player and the computer player.

Players alternately start every game.

Use graphics for generate the playing field and to make the "X"s and "O"s.  Have sounds for the human winning and losing.  (This is required!)

Write this program as an applet.

Rules

Noughts  and Crosses, or Tic Tac Toe, as it is called on different sides of the pond, is probably the most common pencil and paper game around in the western world. The rules are extremely simple. It's so simple it can even be played without pencil & paper, I remember playing it as a child drawing it with a twig in the sand. Surprisingly, some game manufacturers succeed in selling this as a board game.

Number of Players:
2 players

To start:
One player draws a 3 x 3 grid on the paper.

How to Play:

• One player uses the symbol X, the other O.
• Taking turns, the players alternately put an 'X' or 'O' in a empty space in the grid.
   

The end:

When one player fills a row, column, or diagonal of 3 X's or 3 O's (his/her own symbol) this player wins.
