[C++知识库]三子棋小游戏！

今天我们来写一个三子棋小游戏，主要运用的知识是函数调用，数组，循环等。

首先是棋盘菜单的打印：

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

如果玩家玩完儿一局还想玩，可以再次进行，所以此时使用

do

{

}while()

来使这个游戏可以再次进行：

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

下一步，需要把棋盘给制作出来，如示意图：

由示意图可得代码：

void InitBoard(char board[ROW][COL], int row, int col)
//制作棋盘，并且把每个空定义为空格
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		int j = 0;
		for (j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
void DisplayBoard(char board[ROW][COL], int row, int col)
//打印棋盘
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		int j = 0;
		for (j = 0; j < col; j++)
		{
			printf(" %c ", board[i][j]);
			//打印数组中已经存放的元素
			if (j != col - 1)
			{
				printf("|");//在分隔处打印分隔线，最后列不需要打印
			}
		}
		printf("\n");
		if (i != row - 1)//在最后一行不需要打印分隔线
		{
			int j = 0;
			for (j = 0; j < col; j++)
			{
				printf("---");
				if (j != col - 1)
				{
					printf("|");
				}
			}
		 printf("\n");
		}
		
	}
}

此时，棋盘已经打印完毕，接下来就可以开始下棋了。这时我们要明白一个事情，就是必须没下一次棋，打印一次棋盘供玩家查看。代码如下?：

void Player_move(char board[ROW][COL], int row, int col)
//玩家下棋
{
	int x = 0;
	int y = 0;
	while (1)
	{
		printf("请输入坐标\n");
		scanf("%d %d", &x,&y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = '*';
				break;
			}
			else
			{
				printf("此坐标已被占用！\n");
			}
		}
		else
		{
			printf("坐标非法，重新输入！\n");
		}
	}
}
void Computer_move(char board[ROW][COL], int row, int col)
//电脑下棋
{
	printf("电脑走\n");
	while (1)
	{
		int x = rand() % row;
		int y = rand() % col;
		//调用随机数值库函数
		if (board[x][y] == ' ')
		{
			board[x][y] = '#';
			break;
		}
	}
}

此时，如果哪一方首先取得了游戏的胜利，就可以结束游戏。

所以接下来应该设置比赛输赢的条件，如果完成条件，既可以结束游戏。

输赢条件和平局条件的判断：

char iswin(char board[ROW][COL], int row, int col)
//判断输赢
{
	for (int i = 0; i < row; i++)
	{
		if (board[i][1] == board[i][0] && board[i][1] == board[i][2] && board[i][1] == '*')
			return board[i][1];
		if (board[i][1] == board[i][0] && board[i][1] == board[i][2] && board[i][1] == '#')
			return board[i][1];
	}//判断水平的棋子是否相等
	for (int j = 0; j < col; j++)
	{
		if (board[1][j] == board[0][j] && board[1][j] == board[2][j] && board[1][j] == '*')
			return board[1][j];
		if (board[1][j] == board[0][j] && board[1][j] == board[2][j] && board[1][j] == '#')
			return board[1][j];
	}//判断纵行的棋子是否相等
	if (board[1][1] == board[0][0] && board[1][1] == board[2][2] && board[1][1] == '*')
		return board[1][1];
	if (board[1][1] == board[0][0] && 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];
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] == '#')
		return board[1][1];
	//判断交叉的棋子是否相等
	int ret = isdraw(board, ROW, COL);
	if (ret == 1)
		return 'Q';
	else
		return 'C';

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

最后对整个代码进行整理：
