生命游戏（c++/杂谈）

睡觉前刷视频了解到了生命游戏这个东西，今早起来就花了一些时间将游戏写了出来，代码没有多长思路也很简单，规则就是：
(1)当前细胞为死亡状态时，当周围有3个存活细胞时，则迭代后该细胞变成存活状态(模拟繁殖)；若原先为生，则保持不变。
(2)当前细胞为存活状态时，当周围的邻居细胞低于两个(不包含两个)存活时，该细胞变成死亡状态(模拟生命数量稀少)。
(3)当前细胞为存活状态时，当周围有两个或3个存活细胞时，该细胞保持原样。
(4)当前细胞为存活状态时，当周围有3个以上的存活细胞时，该细胞变成死亡状态(模拟生命数量过多)。

代码瞎写的，很乱，图一乐。画图用的是easyx图形库很简单。
有些小bug哦，但不影响大局。
