Game_Of_Life

Rules:

1，Any live cell with fewer than two live neighbors dies, as if caused by under-population.
2，Any live cell with two or three live neighbors lives on to the next generation.
3，Any live cell with more than three live neighbors dies, as if by over-population..
4，Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.
My Code As Follows:

  1 #include<iostream>
  2 #include<vector>
  3 #include<fstream>
  4 #define ALIVE 1        //存活
  5 #define DEAD 0        //死亡
  6 #define MAXROW 5    //最大行
  7 #define MAXCOL 5    //最大列
  8 using namespace std;
  9 using Mat = vector<vector<int>>;
 10 void init_self(Mat & mat);    //用户手动输入数据
 11 bool init_file(Mat & mat);    //从文件读取
 12 void show(const Mat & mat);    //输出，用空格和"X"表示存活状态
 13 void update(Mat & pre_mat, Mat & update_mat);    //跟新状态
 14 void init_date(Mat & mat);    //初始化pre和update的数据
 15 int main() 
 16     Mat pre_mat(MAXROW, vector<int>(MAXCOL));
 17     Mat update_mat(MAXROW, vector<int>(MAXCOL));
 18     init_date(pre_mat);        //先将pre_mat和update_mat置为0
 19     init_date(update_mat);
