三子棋小游戏

三子棋小游戏

程序入口

void test()
{
	int input = 0;
	srand((unsigned int)time(NULL));

	do
	{
		menu();
		printf("请选择:>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();//游戏
			break;
		case 0:
			printf("退出游戏n");
			break;
		default:
			printf("选择错误n");
			break;
		}
	} while (input);
}

int main()
{
	test();
	return 0;
}

menu（）打印菜单

void menu()
{
	printf("********************************n");
	printf("*********  1. play     *********n");
	printf("*********  0. exit     *********n");
	printf("********************************n");
}

效果图

 

game（）函数的实现

void game()
{	
	int input;
	printf("请选择您的难度n");
	printf("********************************n");
	printf("*********  0. 弱智     *********n");
	printf("*********  1. 正常     *********n");
	printf("****   其他任意数字. 神仙   ****n");
	printf("********************************n");
	scanf("%d", &input);
	char ret = 0;
	//存放下棋的数据
	char board[ROW][COL] = { 0 };
	//初始化棋盘为全空格
	InitBoard(board, ROW, COL);
	//打印棋盘
	if ((input != 0) && (input != 1))
	{
		int x = rand() % 3;//0~2
		int y = rand() % 3;//0~2
		board[x][y] = '#';
	}
	//进击的老神仙
	DisplayBoard(board, ROW, COL);

	while (1)
	{	
		
		//玩家下棋
		player_move(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		//判断输赢
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
		//电脑下棋
		if (input == 0) 
		{
			computer_move(board, ROW, COL);//随机下棋
		}
		else if (input ==1)
		{
			computer_move1(board, ROW, COL);//智能下棋
		}
		else
		{	
			computer_move2(board, ROW, COL);//神仙下棋
		}
		DisplayBoard(board, ROW, COL);
		ret = is_win(board, ROW, COL);
		if (ret != 'C')
		{
			break;
		}
	}
	if (ret == '*')
	{
		printf("玩家赢了n");
	}
	else if (ret == '#')
	{
		printf("电脑赢了n");
	}
	else
	{
		printf("平局n");
	}
	//DisplayBoard(board, ROW, COL);
}

效果图  初始化棋盘

void InitBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		int j = 0;
		for (j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}

打印棋盘

void DisplayBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		//打印数据
		int j = 0;
		for (j = 0; j < col; j++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("n");
		//打印分割的行
		if (i < row - 1)
		{
			for (j = 0; j < col; j++)
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
			printf("n");
		}
	}
}

玩家下棋

void player_move(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("玩家下棋n");
	while (1)
	{
		printf("请输入坐标:>");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			//下棋
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = '*';
				break;
			}
			else
			{
				printf("该坐标被占用，请重新输入n");
			}
		}
		else
		{
			printf("坐标非法，请重新输入n");
		}
	}
}

char is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	//判断行
	for (i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
		{
			return board[i][1];
		}
	}
	//判断列
	for (i = 0; i < col; i++)
	{
		if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
		{
			return board[1][i];
		}
	}
	//对角线
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}

	//判断平局
	if (if_full(board, row, col) == 1)
	{
		return 'Q';
	}

	//继续
	return 'C';
}

简单难度 （电脑随机下）

void computer_move(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("电脑下棋:>n");
	while (1)
	{	
		x = rand() % row;//0~2
		y = rand() % col;//0~2
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

标准难度（增加进攻和防守，但是考虑不能无限平局，开局随机而不是随机应变）

void computer_move1(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	int z = 1;
	printf("电脑下棋:>n");
	//进攻
	for (int i = 0; i < 3; i++)
	{
		//行处理
		if ((board[i][0] == '#') && (board[i][1] == '#') && (board[i][2] == ' '))
		{
			board[i][2] = '#';
			z = 0;
			return 0;
		}
		else if ((board[i][2] == '#') && (board[i][1] == '#') && (board[i][0] == ' '))
		{
			board[i][2] = '#';
			z = 0;
			return 0;
		}
		else if ((board[i][2] == '#') && (board[i][0] == '#') && (board[i][1] == ' '))
		{
			board[i][1] = '#';
			z = 0;
			return 0;
		}
		//列处理
		else if ((board[0][i] == '#') && (board[1][i] == '#') && (board[2][i] == ' '))
		{
			board[2][i] = '#';
			z = 0;
			return 0;
		}
		else if ((board[2][i] == '#') && (board[1][i] == '#') && (board[0][i] == ' '))
		{
			board[0][i] = '#';
			z = 0;
			return 0;
		}
		else if ((board[2][i] == '#') && (board[0][i] == '#') && (board[1][i] == ' '))
		{
			board[1][i] = '#';
			z = 0;
			return 0;
		}
	}
	//斜型处理
	if (z == 1)
	{
		if ((board[0][0] == '#') && (board[1][1]) == '#' && (board[2][2] == ' '))
		{
			board[2][2] = '#';
			z = 0;
			return 0;
		}
		else if ((board[2][2] == '#') && (board[1][1]) == '#' && (board[0][0] == ' '))
		{
			board[0][0] = '#';
			z = 0;
			return 0;
		}
		else if ((board[0][2] == '#') && (board[1][1]) == '#' && (board[2][0] == ' '))
		{
			board[2][0] = '#';
			z = 0;
			return 0;
		}
		else if ((board[2][0] == '#') && (board[1][1]) == '#' && (board[0][2] == ' '))
		{
			board[0][2] = '#';
			z = 0;
			return 0;
		}
		else if ((((board[0][0] == '#') && (board[2][2] == '#')) || ((board[2][0] == '#') && (board[0][2] == '#'))) && (board[1][1] == ' '))
		{
			board[1][1] = '#';
			z = 0;
			return 0;
		}
	}

开挂模式（电脑先手，且后面每回合下两子，--其实原理也和随机模式一样，莽夫模式，你大约有1/3的胜率）

void computer_move2(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	printf("电脑下棋:>n");
	while (1)
	{
		x = rand() % row;//0~2
		y = rand() % col;//0~2
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
	while (1)
	{
		x = rand() % row;//0~2
		y = rand() % col;//0~2
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

注：电脑的先手在game中已经预置了

emmm，我写的真垃圾，以后还是和大家分享知识点的内容吧
