一定要用线程，首先，我们先来分析一下如何才能做到让屏幕上的数字不停的变化，这就需要使用线程了，当我们开始抽奖的按钮的时候，线程启动，此时屏幕上的数字开始滚动。当我们点击结束按钮的时候，线程终止，此时就可以显示出抽奖结果了。

真不好玩，写好还真不简单~
中意的话，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。/

QQ抽奖小程序提前开奖的方法有以下几种：
1、在开奖前一段时间内，将参与抽奖的人数减少，让机会变得更加丰厚；
2、在开奖前一段时间，开放更多的中奖方式，来吸引更多的人参与；
3、在开奖前一段时间，活动宣传渠道要多样，注重社交媒体宣传等；
4、在开奖前一段时间，在精准投放流量，让有需求的用户有机会参与；
5、在开奖前一段时间，可以尝试配合多家商家合作，让抽奖更有吸引力；
6、在开奖前一段时间，可以考虑使用抽奖程序的定时开奖功能，让抽奖过程更加透明。
首先打开手机，进入微信。点击抽奖助手功能
选择点击抽奖助手功能。
点击发起抽奖功能
选择点击发起抽奖功能。
点击输入所有抽奖信息后点击发起抽奖功能，选择点击输入所有抽奖信息后点击发起抽奖功能。
打开微信发现页面，点击小程序。搜索“活动抽奖”。然后点击发起抽奖。
完善了奖品信息，填写抽奖说明，可以在这里描述此次抽奖的目的或者小要求，填写两个条件，必须是个人的公众号粉丝才能抽奖。高级功能的使用。
