利用C語言實作人機三子棋游戲

三子棋實作效果

1.首先游戲界面是一個選擇進入游戲或者退出游戲的簡單界面，
2.進入游戲之后出現的是一個3*3的一個棋盤，
3.玩家通過輸入棋盤坐標下棋，機器隨機落子，
4.游戲結束后可以選擇繼續游戲或者退出游戲，

實作代碼

先上代碼，

頭檔案：game.h

#define Row 3
#define Col 3
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

//初始化棋盤
void InitBoard(char board[Row][Col], int row, int col);
//列印棋盤
void DisplayBoard(char board[Row][Col], int row, int col);
//玩家下棋
void PlayerMove(char board[Row][Col],int row,int col);
//電腦下棋
void ComputerMove(char board[Row][Col],int row,int col);
//判斷誰贏
char CheckWin(char board[Row][Col], int row, int col);
