/*
预先将参加抽奖者的资料输入存储起来，主要用结构体数组实现，用结构体表示每项记录，包括身份z号码、姓名、电话、住址等信息。开始抽奖时，屏幕上快速闪动参与者的身份z号码，按任意键停止闪动，把中奖人的信息用显示在屏幕上。可反复抽出一、二、三等奖若干名。
设计实现以下功能：
（1）录入：完成抽奖者信息的输入；
（2）删除：完成抽奖者信息的删除；
（3）修改：允许对已经录入的数据重新进行编辑、修改；
（4）显示：显示所有中奖者的信息；
（5）抽奖：
a. 抽出一等奖 1 名，如果抽过就不能再抽；
b. 抽出二等奖 2 名，如果抽完就不能再抽；
c. 抽出三等奖 5 名，如果抽完就不能再抽；
（6）退出程序。*/
