代码如下:

#include <iostream>
using namespace std;


class GoBangDesk
{
public:
	GoBangDesk() :state('@'), flagWin(false), flagOver(false), flagDraw(false)
	{
		for (int i = 0; i < 20; i++)

				goBangDesk[i][j] = '#';
	}

	void printDesk()
	{
		cout << "         1  2  3  4  5  6  7  8  9 10 11 12 13 14 15" << endl;
		for (int i = 1; i <= 15; i++)
		{
			cout << "        ---------------------------------------------" << endl;
			cout << i<<"\\t";
			for (int j = 1; j <= 15; j++)
			{
				cout << "|" << goBangDesk[i][j]<<"|";
			}
			cout << endl;
		}
		cout<< "        ---------------------------------------------" << endl;
	}

	void clearDesk()
	{
		system("cls");
	}

	void gameProcess()
	{
		int tmpx;
		int tmpy;
		cout << "当前要落的子为:" << state << endl;
		cout << "请输入坐标,进行落子操作:" << endl;
		cin >> tmpx >> tmpy;

		if (tmpx < 1 || tmpx > 15 || tmpy < 1 || tmpy >15)
		{
			cout << "输入有误,请重新输入" << endl;
			system("pause");
			return;
		}

			idx = tmpx;

			goBangDesk[idx][idy] = state;

		}

	}

	void gameStart()
	{

				break;
			}
		}
	}

	void checkDesk() {
		bool flag = false;
		for (int i = 1; i <= 15; i++)
		{

					if (flag) break;
				}
			}
			if (flag) break;
		}
	}
	


private:
	
	void checkWinDfs(int x, int y, int k, int step)
	{
