里面可能有许多不常见的函数或者数据类型，读者自行百度吧。

注解：  
1：COORD是Windows API中定义的一种结构，表示一个字符在控制台屏幕上的坐标。其定义为：

typedef struct _COORD {
        
    short X; // horizontal coordinate（水平方向）
    short Y; // vertical coordinate（垂直方向）
    } COORD;

2：这个结构包含的是控制台光标的信息

typedef struct _CONSOLE_CURSOR_INFO {
        
      DWORD dwSize;// 光标百分比厚度bai（1~100） 
      BOOL  bVisible;// 是否可见
      } CONSOLE_CURSOR_INFO, *PCONSOLE_CURSOR_INFO;
