学习C :生活游戏

学生java开发人员在这里寻找一些用C 程序以新语言为基础的帮助。

问题是，此代码不会在GCC上编译，我的想法为零。

预期的行为作为一组规则的游戏：

游戏表示为2D阵列，带有随机填充的二进制单元格，每个细胞都活着或死亡。

游戏的每个"圆"，单元格根据规则子集生命或死亡。
A。如果一个牢房有4个或更多的现场邻居，它会死亡。
b。如果一个牢房有1个或更少的活着的邻居，那就死了。
C。如果一个死细胞恰好有3个邻居，那么它就会像殖民一样浮现。

为了确定邻居的目的，董事会的每一侧都被认为与对方相邻。因此，右侧与左侧相邻，反之亦然。同样，顶部和底部以及角落。

例如：[0] [0]有8个邻居，上面是[n-1] [n-1]，[n-1] [0]，[n-1] [1]，在相同的行是[0] [n-1]，[0] [1]，下面是[1] [n-1]，[1] [0]和[1] [1]。

运行，直到董事会没有更改或指定的最大周期完成为止。

可能最令人困惑的元素是我选择以最简单的方式来表示这一点，通过将n n raray反映为n 2的n 2阵列，并填充周围的" shell"用代表内部对面邻居的"幽灵价值"。

任何帮助将其从底楼中取出的任何帮助将不胜感激。我去更多阅读。
