C语言学习，鹏哥C语言————三子棋（可进一步拓展N字棋）

本文链接：https://blog.youkuaiyun.com/qq_46512332/article/details/140380318

一、三子棋

三子棋，即井字棋。

二、代码实现

test.c 测试游戏的逻辑
game.c 游戏功能的实现
game.h 游戏代码的申明(函数声明、符号申明)

角色分类：
玩家下棋 PlayerMove
电脑下棋ComputerMove

玩法分类
玩家 VS 电脑
玩家 VS 玩家（待实现）

Main：
（1）menu--->1 or 0 (输入1 表示play，0表示exit)
（2）初始化棋盘
（3）打印棋盘
（4）玩家下棋
（5）电脑下棋
（6）判断输赢

三、具体实现方式

1.主函数逻辑实现

通过do while 循环的方式先打印菜单，再根据用户的输入值，通过switch函数选择是否进行游戏

主函数体中GAME函数实现
2.菜单实现

3.棋盘建立以及初始化和打印

void Initboard(char board[ROW][COL], int row, int col)
{
	//建立棋盘，初始化棋盘
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}

void Displayboard(char board[ROW][COL], int row, int col)
{
	//打印
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
			{
				printf("|");
			}
		}
		printf("\n");
		if (i < row - 1)
		{
			for (j = 0; j < col; j++)
			{
				printf("---");
				if (j < col - 1)
				{
					printf("|");
				}
			}
			printf("\n");
		}
	}
}

设置Initboard函数以实现初始二维数组初始化
设置Displayboard函数以实现棋盘建立，此处利用循环语句构建了如下的结构
%c | %c | %c
--- | --- | ---
%c | %c | %c
--- | --- | ---
%c | %c | %c
此处%c表示初始二维数组的对应位置数据第一个即为board[0][0]

3.玩家下棋以及电脑下棋实现

void PlayerMove(char board[ROW][COL], int row, int col)
{
	while (1)
	{
		int x = 0;
		int y = 0;
		printf("玩家下棋\n");
		printf("请输入坐标：->");
		scanf("%d %d", &x, &y);
		if (board[x - 1][y - 1] == ' ' && board[x - 1][y - 1] != '*' && board[x - 1][y - 1] != '#')
		{
			board[x - 1][y - 1] = '*';
			break;
		}
		else 
		{
			printf("非法输入，请重新输入\n");
		}
	}
}

void ComputerMove(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋\n");
	while (1)
	{
		int x = 0;
		int y = 0;
		x = rand() % row;
		y = rand() % col;
		if (board[x][y] == ' ' && board[x][y] != '*' && board[x][y] != '#')
		{
			board[x][y] = '#';
			break;
		}
	}
}

此处使用if和while函数对二维数组中的非SPACE元素进行填充

4.判断函数

int Is_Win(char board[ROW][COL], int row, int col)
{
	//判断行
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col - 1; j++)
		{
			if (board[i][j] != board[i][j + 1])
			{
				break;
			}
		}
		if (j == col - 1)
		{
			return board[i][0];
		}
	}
	//判断列
	for (i = 0; i < col; i++)
	{
		for (j = 0; j < row - 1; j++)
		{
			if (board[j][i] != board[j+1][i])
			{
				break;
			}
		}
		if (j == row - 1)
		{
			return board[0][i];
		}
	}
	//判断对角线
	for (i = 0; i <= row - 1; i++)
	{
		if (board[i][i] != board[i + 1][i + 1])
		{
			break;
		}
	}
	if (i == row - 1)
	{
		return board[0][0];
	}

	for (i = row -1 ,j = 0; i > 0,j <= col - 1; i--,j++)
	{
		if (board[i][j] != board[i-1][j+1])
		{
			break;
		}
	}
	if (i == 0 && j == col -1)
	{
		return board[row-1][0];
	}
	//平局判断
	int ret = 0;
	if(ret = FULL(board,ROW,COL) == 1)
	{
		return 1;
	}
}

int FULL(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
			{
				return 0;
			}
		}
	}
	if (i == row)
	{
		return 1;
	}
}

这里设置了一个新的FULL函数以判断数组是否被储存圆满

5.函数声明和头文件
