Hello

My first game of TicTacToe and thought I will put the same here after the Game of Mojo and Max 8

Note :- This will compile in Turbo C 3 Only and the zip contains the executable Version also for you to see.

Code: C
#include <iostream.h>
 #include <conio.h>
 #include <stdlib.h>          //For exit(0) function
 #include <dos.h>          //For sleep function
 #include <string.h>          //For strlen

Hello Shabbir,
Its been a long time since I downloaded & ran the Tic Tac Toe program (& perhaps longer time since this program was posted) - so, this may seem a little off-the-mark.

But, we have been taught Tic Tac Toe's basic algorithm as an application of Trees.
i.e., we were taught how tree as a data structure can be used as a game tree to predict the best possible move that can be made by the computer.

However, ur program doesn't involve setting up of any Game Tree, yet, almost every time I lose to the PC!!
Can u tell me what method hav u adopted in coding??

Also, please tell me how to use "ikbhijit( )" or 2D pointers??

Ciao,
Rajiv

How you managed this.

Yes but when I wrote that I just knew printf and scanf in C and nothing more. No knowledge of Data structure.

Simple logic is I want to win and so first I detect where if any saves I need to do so the opponent does not win then places where I can win and then if both the above fails I put them at hard coded position.

ok. So u used pure logic, which is pretty good work - but what bout "ikbhijit( )". If u could just explain it & its usage in brief, then I will be very thankful to you. (Also, kindly recommend some books for learning such functions & advanced C++)

Can you tell me what you meant by module ikbhijit(). I dont see any module with that name in my code.

Also for learning C the book I used can be found here.

Also I prefer online resources and I have clubed them in C++ books and tutorial thread for everyone.

oops - sorry, maybe mixed up someone else's code with yours.
My apologies.

Thx for the suggesting the book.

As a matter of interest, I recently coded a game (mostly in Python) that takes a non-traditional approach. It performs no logical evaluation whatsoever, but plays entirely based on history (experience). I does use a tree, sort of a bastardized general tree. Since there are many equivalent positions (a single 'X' in the upper left corner is equivalent to a single 'X' in any corner), the tree contains only a set of Basic Positions. This actually amounts to fewer than 800.

The effectiveness of any response is proportional to the number of games, in which it was used, that resulted, ultimately, in a win, loss, or draw.

There is a standalone version written in Python with wxWidgets. The bulk of the Python code is also used (server side) in a web version which uses asynchronous http-xml requests to send the player's move and return the machine's response. Each move/response is treated as a single, detached problem, except in training mode. The web version can, of course, be played using any browser that supports asynchronous http-xml (often referred to as AJAX). The standalone version requires that you have Python and wxWidgets available.

If there's any interest I will post a link to the web game and another link to a zip file with the code. I notice that there's no Python (or Other Languages) forum, so I'm not sure exactly where it should be posted.

DaWei You can post that in the Programming section and soon we are planning to have python section as we have some resources being added in that direction and it will be moved accordingly.
