c语言实现三子棋游戏

此游戏存在一个头文件和两个源文件

1.game.h

#pragma once

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


#define ROW 3
#define COL 3

//函数的声明
//初始化棋盘
void  InitBoard(char board[ROW][COL], int row, int col);

//打印棋盘的函数
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);

int IsFull(char board[ROW][COL], int row, int col);
//1.玩家获胜 - *
//2.电脑获胜 - #
//3.平局     - Q
//4.游戏继续 - C

//判断游戏是否有输赢

实现功能

1.选择玩或者不玩

2.玩家选坐标进行游戏

3.电脑选择坐标进行游戏

4.判断玩家或电脑是否获胜

玩家获胜：

电脑获胜：

平局：
