[C++知识库]c语言实现三子棋

通过数组的学习，就可以结合之前的知识做出一个小游戏：三子棋

test.c 游戏的测试逻辑

game.c 游戏的实现逻辑

game.h 游戏实现函数的声明

game.h

#pragma once

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

#define ROW 3
#define COL 3

//初始化棋盘
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 player_move(char board[ROW][COL], int row, int col);

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

//判断输赢对的代码
// 玩家赢 *
// 电脑赢 #
// 平均   Q
// 继续   C
