两个玩家玩, 不是对电脑, 上面是自己写的,请帮忙修改!
//isAvailable();

//makeMove();

//playerHasWon();
这是还没写的子程序..
有问题可以加我Q, 谢谢高手门!!

C++实现井字棋小游戏(写得不好,留作纪念!!!)

回宿舍路上，同学问起我能不能用C++写个五子棋游戏，我说应该挺简单的，但是我不会写，然后他说不用写五子棋，就写井字棋吧！！！我说试试吧！！！
(不过说实话，写得不是很好，留作纪念吧!!!)

代码如下:

#include <iostream>
using namespace std;
const int N = 5;
bool vis[N][N] = { false };
bool tttSon[N][N] = { false };
char tttDesk[N][N];
int dx[] = { 1,-1,1,-1,0,0,1,-1 };
int dy[] = { 0,0, 1,-1,1,-1,-1,1 };
bool isEnd = false;

void printError()
{
	cout << "无效输入,按任意键后，重新输入" << endl;
}

void initDesk()
{
	for (int i = 1; i <= 3; i++)
		for (int j = 1; j <= 3; j++)
			tttDesk[i][j] = '@';
}

void printInterface(char son)
{
	int flagX = 0, flagY = 0;
	for (int i = 1; i <= 3; i++)
	{
		for (int j = 1; j <= 3; j++)
		{
			cout << vis[i][j] << " ";
			if (vis[i][j])
			{
				flagX = i;
				flagY = j;
			}
		}
		cout << endl;
	}
	cout << "当前要落的子为:" << son << endl;
	cout << "当前光标的位置在第" << flagX << "行," << "第" << flagY << "列" << endl;
	cout << "-------------------------------------" << endl;

	for (int i = 1; i <= 3; i++)
	{
		for (int j = 1; j <= 3; j++)

			cout << tttDesk[i][j] << " ";
		}
		cout << endl;
	}
}
