定义函数

//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);

//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);

//玩家下棋
void player_move(char board[ROW][COL], int row, int col);

//电脑下棋
void computer_move(char board[ROW][COL], int row, int col);

//判断输赢
char is_win(char board[ROW][COL], int row, int col);//静态方法，只能实现，具体为3的查找，修改行和列，不能运行。

菜单

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

逻辑实现

void game()
{
	//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
	DisplayBoard(board, ROW, COL);
	int num = 0;
	while (1)
	{
		//玩家下棋
		player_move(board, ROW, COL);
		num++;
		if (is_win(board, ROW, COL) == '*')
		{
			printf("玩家赢\n");
			DisplayBoard(board, ROW, COL);
			break;
		}
		//电脑下棋
		if (num == ROW * COL)
		{
			DisplayBoard(board, ROW, COL);
			printf("平局\n");
			break;
		}
		computer_move(board, ROW, COL);
		num++;
		DisplayBoard(board, ROW, COL);
		if (is_win(board, ROW, COL) == '#')        //返回0，继续；返回1，玩家赢；返回2，电脑赢；返回3，平局
		{
			printf("你是笨蛋\n");
			//DisplayBoard(board, ROW, COL);
			break;
		}
	}
}

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");
		}
	}
}

电脑下棋

void computer_move(char board[ROW][COL], int row, int col)
{
	while (1) {
		int row = rand() % ROW;   //0~2
		int col = rand() % COL;   //0~2
		if (board[row][col] == ' ')
		{
			board[row][col] = '#';
			break;
		}
	}
}

判断输赢

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