一、怎么实现？

        大体框架构建：需要啥？菜单（可供玩家选择）->游戏主体->玩家选择后进行操作->如果玩家选错怎么办？返回，让这小b崽子重新选！->不想玩怎么办？允许他不玩这旷世之作[○･｀Д´･ ○]

于是根据大体思路首先写出了大体框架：

菜单：

void menu()//菜单
{
	printf("---------------------------\n");
	printf("|*************************|\n");
	printf("|*******  1.play  ********|\n");
	printf("|*******  0.exit  ********|\n");
	printf("|*************************|\n");
	printf("---------------------------\n");
}

 主函数：

int main()
{
	int input = 0,flag=0;
	do
	{
		menu();
		printf("请选择：");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			if(flag==0)
			printf("\n              -- 三子棋 --\n \n");
			flag = 1;
			game();
			break;
		case 0:
			printf("--退出成功--\n");
			break;
		default:
			printf("--输入错误，请重新输入！--\n");
		}
	} while (input);
	return 0;
}

对此我们的重点现在便是在构建game（）这个函数了！◍˃ ᵕ ˂◍

 二、game（）主体的构建

        首先还是要先构思一下大体框架->要实现什么功能？人机大战! 玩家vs玩家!->这样便又需要一个菜单来供选择了 ε=(´ο｀*)))唉 ->用什么来做比较合适？数组！二维数组！->需要什么？棋盘！->用了数组因此需要初始化，需要打印棋盘，需要对于玩家落子和电脑落子进行分别的操作！->最主要的操作！判断输赢！->棋盘满算平局（重点），执子 * 和  # 哪边先达到要求哪边胜出！

大体思路想好了，实现如下：

#define _CRT_SECURE_NO_WARNINGS 01

#include"game.h"

void menu()//菜单
{
	printf("---------------------------\n");
	printf("|*************************|\n");
	printf("|*******  1.play  ********|\n");
	printf("|*******  0.exit  ********|\n");
	printf("|*************************|\n");
	printf("---------------------------\n");

	}
}

{
	for (int i = 0; i < row; i++)
	{

三、重点在判断输赢！

        平局！最主要的就是判满！便历棋盘看是否剩下空格->也就是没落子的地方，若全满返回1以告诉后续接受的函数棋盘满了，可以判平！

int isfull(char board[ROW][COL], int row, int col)//判断棋盘是否满
{
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
				return 0;
		}
	}
	return 1;
}

        玩家或者电脑赢！判断方法都是一样的！最主要的就是怎么判赢！思路->先找到要判赢玩家或电脑所执棋子，这里是‘*’，找到了便可以进行判断了!->分为横向和纵向以及斜向。横向和纵向太斜向的思路都是差不多的-极限。->首先说明为什么我们只判断右下和左下，前面横向和纵向也是为啥只判断一边就行了，因为前边我们的查找：找到‘*’才进行判断。那么之前我们就都判断过了一边，为什么呢？因为我们的起点是从0,0开始的，我们没有左边也没有上边，也没有左上右上。那么接下来的位置实际上我们已经判断过了一边了，只需要判断另一边即可。

（也许是我思考有误？希望大家能帮忙指出Ծ‸Ծ）

int awin(char board[ROW][COL], int row, int col)//a玩家赢
{
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			if (board[i][j] == '*')
			{
				if (j + 2 < col)//横向
				{
					if (board[i][j] == board[i][j + 1] && board[i][j + 1] == board[i][j + 2])
						return 2;
				}
				if (i + 2 < row)//纵向
				{
					if (board[i][j] == board[i + 1][j] && board[i + 1][j] == board[i + 2][j])
						return 2;
				}
				if ((i + 2 < row) && (j + 2 < col))//右下
				{
					if (board[i][j] == board[i + 1][j + 1] && board[i + 1][j + 1] == board[i + 2][j + 2])
						return 2;
				}
				if ((i + 2 >= 0) && (j - 2 >= 0))//左下
				{
					if (board[i][j] == board[i + 1][j - 1] && board[i + 1][j - 1] == board[i + 2][j - 2])
						return 2;
