C语言实现三子棋

三子棋是黑白棋的一种。三子棋是一种民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙、井字棋等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。但是，有很多时候会出现和棋的情况。

利用宏定义来定义棋盘的大小，因为井字棋需要一个3*3的棋盘，为了避免魔幻数字（在后续代码中出现，不能很直观的看出是长还是宽）的出现，我们用ROW和COl来代替

void init(char board[MAX_ROW][MAX_COL]) {

	for (int row = 0; row < MAX_ROW; row++) {

		for (int col = 0; col < MAX_COL; col++) {

			board[row][col] = ' ';

		}

	}

	srand((unsigned int)time(0));

}
//给用户打印一个棋盘
void printBoard(char board[MAX_ROW][MAX_COL]) {

	system("cls");

	for (int row = 0; row < MAX_ROW; row++) {

		printf("+--+--+--+n");

		for (int col = 0; col < MAX_COL; col++) {

			printf("| %c", board[row][col]);

		}

		printf("|");

		printf("n");

	}

	printf("+--+--+--+n");

}
//玩家落子函数
void playerMove(char board[MAX_ROW][MAX_COL]) {

	while (1) {

		printf("请玩家落子!");

		printf("请输入你要落子的位置(row col):");

		int row = 0;

		int col = 0;

		scanf("%d %d", &row, &col);

		if (row < 0 || row > MAX_ROW || col < 0 || col > MAX_COL) {

			printf("你的输入有误,请重新输入!n");

			continue;

		}

		if (board[row][col] != ' ') {

			printf("你输入的位置已经有子,无法继续落子!n");

			continue;

		}

		board[row][col] = 'x';

		break;

	}





}
//电脑落子函数
void computerMove(char board[MAX_ROW][MAX_COL]) {

	printf("轮到电脑落子!n");

	while (1) {

		int row = rand() % MAX_ROW;

		int col = rand() % MAX_COL;

		if (board[row][col] == 'x') {

			continue;

		}

		board[row][col] = 'o';

		break;

	}

}
//判断是否和棋
int isFull(char board[MAX_ROW][MAX_COL]) {

	for (int row = 0; row < MAX_ROW; row++) {

		for (int col = 0; col < MAX_COL; col++) {

			if (board[row][col] == ' ')

				return 0;

		}

	}

	return 1;

}
//判断是否连成一条线
char checkWinner(char board[MAX_ROW][MAX_COL]) {

	int row = 0;

	int col = 0;

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

	}

	for (col = 0; col < MAX_COL; col++) {

			return board[0][col];

		}

	}

	if (board[0][0] != ' ' && board[0][0] == board[1][1] && board[0][0] == board[2][2]) {

	}

		return board[0][2];

	}

	if (isFull(board)) {
//棋盘满返回一个q
		return 'q';

	}
//棋盘没满返回一个空字符
	return ' ';

}

int main() {

	char board[MAX_ROW][MAX_COL] = { 0 };

	char winner = ' ';

	init(board);

	while (1) {

		printBoard(board);

		//system("pause");

		playerMove(board);

		checkWinner(board);

		winner = checkWinner(board);

		}

		computerMove(board);

		winner = checkWinner(board);

		if (winner != ' ') {

			break;

		}

	}

	if (winner == 'x') {

		printf("恭喜你,你赢了!!!");

	}

	else if (winner == 'o') {

		printf("你真菜,竟然输了");

	}

	else {

	}

	return 0;

}
