This project is the two players TIC-TAC-TOE game, but using the gui library to make the graphic.

1/6 of the project grade is based on which concepts from OPL are demonstrated in your project. Please identify them here. Be brief; a simple list and one-sentence explanation for each concept should be adequate; e.g.:
Data abstraction – each button and frame are defined using data abstraction. (define fr (new frame% [label "TIC-TAC-TOE"])) (define panel1 (new horizontal-panel% [parent fr] [alignment '(center center)])) (new button% [parent panel1] [label"1"] [min-width 150] [min-height 150] [font fz] [callback callback]) Symbolic manipulate – used to transform x->‘X and o->‘O for use in the list. (define o 'O) (define x 'X) Cond – used to check whether the user is winning, the board is full, the users click the same button, or users click the available button. (cond [(winner? board) (begin (send winning-msg set-label winning-player) (send wn show #t))] [(= count 9) (send dw show #t)] Lists - used to keep track of the game board and used to check for the winner. (define board '(1 2 3 4 5 6 7 8 9)) Type Conversions – used to convert some data. For instance, string->symbol. (string->symbol (send btn get-label)) Environment Variables – Use set! function to change the global variables (set! click (string->number (send btn get-label))) (set! board (newboard board click first-player))
racket/gui/base to create the game board and the buttons for the users to click.
This is the simple two players TIC-TAC-TOE game. I think there is not much innovation. But I learned a lot from this project. For example, I have to find the way to make the callback function of the button to work with my code.
How the program Works
Technology Used Block Diagram
Create a simple block diagram of your software system that illustrates the major technical components and how they interact; e.g.:
Please use this area to include any additional information you would like to include that did not fit into any of the previous categories.
The total write-up, including screen shot and block diagram, should be two to three pages in length (when printed).
