C++实现井字棋小游戏(写得不好,留作纪念!!!)

Posted 2021-06-23 Wecccccccc

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;
	}
}

void checkPos(int &sonX,int &sonY)
{
	for (int i  =1;i<=3;i++)
		for (int j = 1; j <= 3; j++)
		{
			if (!tttSon[i][j])
			{
				sonX = i;
				sonY = j;
				vis[sonX][sonY] = true;
				return;
			}
		}
}




bool checkWinOfDfs(int x, int y,int step,char me,int k)
{
	if (step == 3) return true;
	int xx = x + dx[k];
	int yy = y + dy[k];
	if (xx < 1 || xx > 3 || yy < 1 || yy > 3 || tttDesk[xx][yy] != me || tttDesk[xx][yy]=='@') return false;
	/*cout << xx << " " << yy << endl;*/
	checkWinOfDfs(xx, yy, step + 1, me, k);

}


void operatorDesk(int &sonX,int &sonY,char &son)
{
	char sonIng;
	bool flag = false;
	initDesk();
	int cnt = 0;
	while (true)
	{
		bool winFlag = false;
		if (cnt > 4 && tttDesk[sonX][sonY]!='@')
		{
			/*cout << sonX << " " << sonY << endl;*/
			for (int k = 0; k < 8; k++)
			{
				if (checkWinOfDfs(sonX, sonY, 1, tttDesk[sonX][sonY], k))
				{
					winFlag = true;
				}
				if (winFlag)
				{
					if (tttDesk[sonX][sonY]=='O')
					cout << "Winer is O" << endl;
					else cout << "Winer is X" << endl;
					isEnd = true;
					return;
				}
			}
			int cnt1 = 0;
			for (int i = 1;i<=3;i++)
				for (int j = 1; j <= 3; j++)
				{
					if (tttSon[i][j]) cnt1++;
