C program to implement a TIC TAC TOE game


Write a C program to implement a TIC TAC TOE game.This program is a small game Tic Tac Toe in C programming.

Here two users can play this game and after completing the game program will show the winner user name. This program is created using by Two Dimensional Array


Below is the source code of the C program to implement a TIC TAC TOE game which is successfully compiled and run on the windows system.The Output of the program is shown below.


SOURCE CODE : :
