如何让玩家按任意键以后退出游戏？ 这么写貌似不行……

fflush(stdin)
或者
flushall()

void GameOver()
{
Sleep(1000);
setcolor(RED);
setfont(16,0,"Tahoma");
outtextxy(500,240,"Game Over");
Sleep(1000);
flushall();//新增的
_getch();
return;
}
经过试验还是不行，仍然自己退……

void GameOver()
{
Sleep(1000);
setcolor(RED);
setfont(16,0,"Tahoma");
outtextxy(500,240,"Game Over");
Sleep(1000);
flushall();//新增的
_getch();
return;
}
int WolfMove(int map[21][21], dtype &Wolf, dtype Player)
{
//移动中
if( (map[Wolf.x][Wolf.y]&PLAYER) ==PLAYER)
{
GameOver();
return 1;
}
map[Wolf.x][Wolf.y]+=WOLF;
return 0;
}
int main()
{
//玩家移动
else if( (map[Player.x][Player.y]&WOLF)==WOLF)
{
GameOver();
break;
}
}

我还是决定放全部代码了……至少它能编译运行，而且还不算是特别长……

不知道为什么一放上来缩进就变恶心了……

还真是个好主意…… 这是源代码 http://pan.baidu.com/share/link?shareid=154828&uk=3154460426

不用getch，用while(!kbhit());如果仍退出，while前面加个键盘缓存清空函数.

看到代码了。
要是用 flushall() 不行，就试试这个：
FlushConsoleInputBuffer(GetStdHandle(STD_INPUT_HANDLE));
_getch();
应该是肯定没问题的，呵呵。

bar((x-1)*24+3, (y-1)*24+3, x*24-3, y*24-3) 能问一下这是什么意思么？我刚学有点不懂

getch多恶心

不知道exit（0）；这句是否可以解决你的问题？
