Question
In C programming Implement an interactive tic tac toe game where player 2 is automated by the computer. The game starts by printing an empty board. Each player takes turns and adds an ’X’ or an ’O’ to the appropriate location. The game ends when the users or the computer wins, or the board is full. Your code should employ at least the following two functions.
int check board(int x[ ][3]); // returns 0 if player 1 wins, 1 if player 2 wins, or 2 if tie
void print board(int x[][3]); // prints the board on screen
only use 2Darrays and #include <stdio.h> please
