基于C语言实现三子棋游戏

我是靠谱客的博主畅快发卡，这篇文章主要介绍基于C语言实现三子棋游戏，现在分享给大家，希望可以做个参考。

说到三子棋，我想大家一定不陌生吧，它也是我童年中的一部分，今天我们用C语言来实现一下简易版的三子棋。

首先，介绍一下游戏规则：

1.在一个九宫格上进行下棋；
2.玩家两名，双方先后落子；
3.若在一条直线上有三颗同一玩家的棋子，则该玩家赢，若棋盘下满也没有出现三颗棋子在一条直线上，则为平局。

设计思路如下：

1.用do…while循环可以保证玩完一把还能接着玩，玩家可以自行选择继续玩还是退出。
2.用一个3x3的二维数组来存放玩家和电脑下的棋子，再进行判断输赢。
3.进行游戏的棋盘如下：

代码如下：

头文件game.h：

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

#define ROW 3
#define COL 3

//棋盘初始化
void InitBoard(char board[ROW][COL], int row, int col);

// 打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);

//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);

//电脑下棋
void ComputerMove(char board[ROW][COL], int row, int col);

//判断输赢
char IsWin(char board[ROW][COL], int row, int col);

//判断游戏输赢
//要返回4种不同的状态
//玩家赢 - '*'
//电脑赢 - '#'
//平局 -  ‘Q'
//继续 -   'C'
