} 头文件以及库函数：
主函数：
各函数所产生的作用：
Initgraph：设定长为Weight,宽为High的窗口
Init()：初始化数据，即导入文件中的图片，给各元素赋初值
While()：保证该页面不断刷新、不断更改数据，即保证游戏的流畅进行
Show()：输出各项数据，如显示背景、输出飞机子弹图片
Move()：控制飞机、子弹的移动
PlayerShow()：子弹射中敌机/player飞机撞到敌机
Search()：判断player飞机是否阵亡
BeginBatchDraw()：开启双缓存、防止图片频闪，将其存储在内存中
FlushBatchDraw()：打开内存中的图片
EndBatchDraw()：结束图片的放映
