c语言程序设计——抽奖程序

真不好玩，写好还真不简单~

中意的话，指侍多加点分！测试过了～

/*

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. 抽出一链带等奖 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。*/
