一、介绍

三子棋，民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。如果两个人都掌握了技巧，那么一般来说就是平棋。一般来说，下在中间最有利，下在角上次之，下在边上再次之。最大的好处就是随便找个地方就可以玩这个简单而有趣的游戏了。

二、游戏实现

        设计菜单

        首先我们需要一个主函数main来设计游戏首页面菜单并来选择进入游戏或者退出游戏。在运行程序时可能玩家会输入错误，所以用while(1)来死循环游戏菜单页面。

#include"Game.h"

int main()
{
	//设置界面
	system("title 简易三子棋");
	system("mode con cols=32 lines=32");
	system("color F0");

	int select = 1;
	while (select)
	{
		printf("********************************\n");
		printf("*        简 易 三 子 棋        *\n");
		printf("********************************\n");
		printf("*     [1]开始      [0]退出     *\n");
		printf("********************************\n");
		printf("请选择：>");
		scanf("%d", &select);
		if (select == 0)
			break;
		if (select != 1)
		{
			printf("输入有误！\n");
			continue;
		}

		//开始游戏
		BeginGame();
	}
	printf("游戏结束，欢迎下次来玩！\n");
	return 0;
}

         由运行截图可见，输入错误数字则会死循环，输入0则退出程序。

        设计游戏流程

        进入游戏后编写一个BeginGame函数来设计游戏流程，其中可以随机让电脑先下棋或者让玩家先下棋，和棋后判断你是否要重来。

int BeginGame()
{
	//1 初始化游戏
	InitializeGame();

	char winner;

	//2 随机下棋者
	int Return = RandomChessPlayer();
	if (Return == 0)
	{
        //3 进入游戏
		while (1)
		{
			//4 显示棋盘
			ShowChessBoard();
			//5 玩家下棋
			PlayerMove();
			//6 判断结果
			winner = CheckResult();
			if (winner != 'c')
				break;
			//7 电脑下棋
			ComputerMove();
			//8 判断结果
			winner = CheckResult();
			if (winner != 'c')
				break;
		}
		
	}
	else
	{
		while (1)
		{
			//4 电脑下棋
			ComputerMove();
			//5 判断结果
			winner = CheckResult();
			if (winner != 'c')
				break;
			//6 显示棋盘
			ShowChessBoard();
			//7 玩家下棋
			PlayerMove();
			//8 判断结果
			winner = CheckResult();
			if (winner != 'c')
				break;
		}
	}

	//9 宣布结果
	if (winner == 'x')
		printf("恭喜你，玩家胜利.\n");
	else if (winner == 'o')
		printf("很遗憾，电脑胜利.\n");
	else
	{
		printf("和棋，是否继续[y/n]:");
		while (1)
		{
			char a[1];
			scanf("%s", a);
			if (a[0] == 'y')
				BeginGame();
			else if (a[0] == 'n')
				break;
			else
				printf("输入有误，清重新输入：>");
		}
	}
	return 0;
}

以下是对游戏流程的细化实现

初始化游戏

        我们可以用二维数组来确定一个3×3的版块，把3×3数组都初始化为空字符。

void InitializeGame()
{
	for (int i = 0; i

显示棋盘 

       将3×3数组打印出来，一个简易的棋盘就做好了

void ShowChessBoard()
{
	for (int i = 0; i

下棋 

        设立玩家下棋为字符‘x’，电脑下棋为字符‘o’；玩家来通过坐标实现下棋，电脑先确定是否玩家下一步可能获胜，如果可能获胜，则下到玩家可能获胜的位置，否则随机下棋。

void PlayerMove()
{
	printf("请玩家落子:\n");

	int row, col;
	while (1)
	{
		printf("请输入棋子的坐标(row:col):>");
		scanf("%d %d", &row, &col); 
		if (board[row - 1][col - 1] != ' ')
		{
			printf("输入的位置已被占用，请重新输入....\n");
			continue;
		}

		board[row - 1][col - 1] = 'x';
		break;
	}
}

void ComputerMove()
{
	int row, col;
	srand(time(0));
	while (1)
	{
		//下玩家可能赢的位置
		if (board[0][0] == 'x' && board[0][1] == 'x' && board[0][2] == ' ')
		{
			board[0][2] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[0][1] == 'x' && board[0][0] == ' ')
		{
			board[0][0] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[0][0] == 'x' && board[0][1] == ' ')
		{
			board[0][1] = 'o';
			break;
		}
		else if (board[1][0] == 'x' && board[1][1] == 'x' && board[1][2] == ' ')
		{
			board[1][2] = 'o';
			break;
		}
		else if (board[1][2] == 'x' && board[1][1] == 'x' && board[1][0] == ' ')
		{
			board[1][0] = 'o';
			break;
		}
		else if (board[1][2] == 'x' && board[1][0] == 'x' && board[1][1] == ' ')
		{
			board[1][1] = 'o';
			break;
		}
		else if (board[2][0] == 'x' && board[2][1] == 'x' && board[2][2] == ' ')
		{
			board[2][2] = 'o';
			break;
		}
		else if (board[2][2] == 'x' && board[2][1] == 'x' && board[2][0] == ' ')
		{
			board[2][0] = 'o';
			break;
		}
		else if (board[2][2] == 'x' && board[2][0] == 'x' && board[2][1] == ' ')
		{
			board[2][1] = 'o';
			break;
		}
		else if (board[0][0] == 'x' && board[1][0] == 'x' && board[2][0] == ' ')
		{
			board[2][0] = 'o';
			break;
		}
		else if (board[0][0] == 'x' && board[2][0] == 'x' && board[1][0] == ' ')
		{
			board[1][0] = 'o';
			break;
		}
		else if (board[1][0] == 'x' && board[2][0] == 'x' && board[0][0] == ' ')
		{
			board[0][0] = 'o';
			break;
		}
		else if (board[0][1] == 'x' && board[1][1] == 'x' && board[2][1] == ' ')
		{
			board[2][1] = 'o';
			break;
		}
		else if (board[0][1] == 'x' && board[2][1] == 'x' && board[1][1] == ' ')
		{
			board[1][1] = 'o';
			break;
		}
		else if (board[1][1] == 'x' && board[2][1] == 'x' && board[0][1] == ' ')
		{
			board[0][1] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[1][2] == 'x' && board[2][2] == ' ')
		{
			board[2][2] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[2][2] == 'x' && board[1][2] == ' ')
		{
			board[1][2] = 'o';
			break;
		}
		else if (board[1][2] == 'x' && board[2][2] == 'x' && board[0][2] == ' ')
		{
			board[0][2] = 'o';
			break;
		}
		else if (board[0][0] == 'x' && board[1][1] == 'x' && board[2][2] == ' ')
		{
			board[2][2] = 'o';
			break;
		}
		else if (board[0][0] == 'x' && board[2][2] == 'x' && board[1][1] == ' ')
		{
			board[1][1] = 'o';
			break;
		}
		else if (board[1][1] == 'x' && board[2][2] == 'x' && board[0][0] == ' ')
		{
			board[0][0] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[1][1] == 'x' && board[2][0] == ' ')
		{
			board[2][0] = 'o';
			break;
		}
		else if (board[0][2] == 'x' && board[2][0] == 'x' && board[1][1] == ' ')
		{
			board[1][1] = 'o';
			break;
		}
		else if (board[2][0] == 'x' && board[1][1] == 'x' && board[0][2] == ' ')
		{
			board[0][2] = 'o';
			break;
		}
		else
		{
			//随机产生位置
			row = rand() % ROW;
			col = rand() % COL;

			if (board[row][col] == ' ')
			{
				board[row][col] = 'o';
				break;
			}
		}
	}
}

判断结果

        结果分为四种（玩家赢x，电脑赢o，和棋h，未下满继续c），当玩家或者电脑的棋子连成一行或者一列又或者连成对角线时，有一方获胜；当棋盘下满时，应判断为平局，所以判断输赢的函数就需要返回值。
