編寫程式，實現三子棋（五子棋）遊戲

將define定義的Row、Col改為5即可實現5*5棋盤的五子棋遊戲

程式程式碼如下：

game.h

#ifndef __GAME_H__
#define __GAME_H__
#include<stdio.h>
#define Row 3
#define Col 3

void ChessBoard(char arr[Row][Col], int row, int col);
void DisplayBoard(char arr[Row][Col], int row, int col);
void PlayerMove(char arr[Row
 
][Col], int row, int col);
void ComputerMove(char arr[Row][Col], int row, int col);
char CheckWin(char arr[Row][Col], int row, int col);
int IsFull(char arr[Row][Col], int row, int col);
#endif//__GAME_H__
