自己跑的甘雨镇楼

三子棋，具有玩家落子、电脑随机落子、判断输赢的简单功能

1.打印选择菜单

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

2.通过do while循环实现开始游戏和多次进行游戏

int main()
{
    int input = 0;
	do
	{
		menu();
		printf("请选择—>");
		scanf("%d", &input);
		switch (input)
		{
		case(1):
			printf("开始游戏\n");
			game();
			break;
		case(0):
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误，重新选择\n");
			break;
		}
	} while (input);

	return 0;
}

3.实现game函数

通过#define定义的标识符常量，可以方便修改棋盘大小

#define ROW 3
#define COL 3

3.1 初始化棋盘并打印

// 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] = ' ';//初始化为空格
		}
	}
}

//打印棋盘 
void DisplayBoard(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++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
			{
				printf("|");//打印纵向分隔线
			}
		}
		printf("\n");
		if (i < row - 1)
		{
			printf("---");//打印横向分隔线
			for (j = 0; j < row -1; j++)
			{
				printf("|---");//打印横向分隔线
			}
			printf("\n");
		}
	}
}

对应game函数

void game()
{
	char board[ROW][COL] = {0};
	InitBoard(board, ROW, COL);
	DisplayBoard(board, ROW, COL);
}

3.2 实现玩家下棋

void PlayerMove(char board[ROW][COL],int row,int col)//玩家行动
{
	printf("玩家下棋\n");
	while (1)
	{
		printf("请输入坐标，例如3 3->\n");
		int x = 0;
		int y = 0;
		scanf("%d %d", &x, &y);
		//判断坐标是否可以落子
	
			if (x <= ROW && y <= COL && x > 0 && y>0)
			{
				if (board[x - 1][y - 1] == ' ')//如果目的坐标为空，则下子*
				{
					board[x - 1][y - 1] = '*';
					break;//输入坐标无法下子则重复输入
				}
				else
					printf("坐标被占用，请重新输入\n");
			}
			else
				printf("坐标非法，请重新输入\n");
	}
}

3.3实现电脑随机下棋

void ComputerMove(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;
		y = rand() % col;//生成范围0到row-1的随机数
		if (board[x][y] == ' ')//坐标合适则落子 #
		{
			board[x][y] = '#';
			break;//目的坐标不合适则重复生成随机数
		}
	}
}

使用rand函数需要包含stlib.h和time.h

并在主函数中加上srand((unsigned int)time(NULL));

3.4实现输赢判断

通过函数返回值判断玩家赢/电脑赢/平局/继续游戏

返回*玩家赢

返回#电脑赢

返回0平局

返回c棋盘不满继续游戏

char IsWin(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	//判断行
	for (i = 0; i < row; i++)
	{
		
		for (j = 0; j < col-2; j++)
		{
			if (board[i][j] == board[i][j + 1] && board[i][j] == board[i][j + 2] 
                && board[i][j]!=' ')
				return board[i][j];
		}
	}
	//判断列
	for (j = 0; j < col; j++)
	{
		for (i = 0; i < row - 2; i++)
		{
			if (board[i][j] == board[i + 1][j] && board[i][j] == board[i + 2][j] 
                && board[i][j] != ' ')
				return board[i][j];
		}
	}
	//对角线
	for (i = 0; i < row - 2; i++)
	{
		for(j = 0; j< col -2; j++)
		{
			if (board[i][j] == board[i + 1][j + 1] && board[i][j] == board[i + 2][j + 2]                 
                && board[i][j] != ' ')//右斜对角线
				return board[i][j];
		}
	}
	for (i = 1; i < row - 1; i++)
	{
		for (j = 1; j < col - 1; j++)
		{
			if (board[i][j] == board[i - 1][j + 1] && board[i][j] == board[i + 1][j - 1] 
                && board[i][j] != ' ')//左斜对角线
				return board[i][j];
		}
	}
	//棋盘不满则继续游戏
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
				return 'c';
		}
	}
	return 0;//上述条件都不满足则为平局
}

4. 整合game函数

void game()
{
	char board[ROW][COL] = {0};
	InitBoard(board, ROW, COL);//初始化棋盘
	DisplayBoard(board, ROW, COL);//打印棋盘
	char ret = 0;
	while(1)
	{
		PlayerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'c')//IsWin函数在棋盘不满时返回c
			break;//不为c（即棋盘满）终止循环，判断结果
		ComputerMove(board, ROW, COL);
		DisplayBoard(board, ROW, COL);
		ret = IsWin(board, ROW, COL);
		if (ret != 'c')
			break;
	}
	switch (ret)
	{
	case 0:
		printf("平局\n");
		break;
	case '*':
		printf("玩家赢\n");
		break;
	case '#':
		printf("电脑赢\n");
	}
}

5.整体代码

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

// 初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{

		{

		}
	}
}

//打印棋盘 
void DisplayBoard(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++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
			{
				printf("|");
			}
		}
		printf("\n");
		if (i < row - 1)
		{
			printf("---");
			for (j = 0; j < row -1; j++)
			{
				printf("|---");
			}
			printf("\n");
		}
	}
}

	}

		}
	}
	//列
	for (j = 0; j < col; j++)

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