帮忙做个C语言程序,谢谢!再麻烦写完整点,我是个菜鸟!!!谢谢谢谢!!!

//VC++6。0下调试通过
//这是用C++写的一个简单的抽获程序。你自己试试吧。
/*抽奖程序
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，
包括身份证号码、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证号码，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：*/
