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。/

先把各种可能性存在一个数组里。比如10个纸条上各有一句话,只有抽中某句话才算中奖,那么就把这十句话以字符串形式存放在数组A中。
然后就可以开始抽奖了。
用户选择抽奖,程序就使用rand函数生成一个随机数N,求N%10就能得到一个介于0到9之间的整数 i ,然后看A[i]的值是否是那个中奖的字符串,是就中奖。
当然了,你可以设计得复杂些,但原理就是这样了。
题主,您好,制作这个小程序的方法非常多,主要是看您要做成什么样子的,在哪里使用,不管是网页还是小程序,直接用JS也可以实现,如果想要做的严谨点,可以利用PHP或者JAVA做后台,将抽奖记录数据存储到数据库中去。
在窗体上添加一个command1,一个timer1,label1(0~5)
控件数组(添加一个label1,然后再复制5个,共6个,用来显示数字),代码如下:
Private
Sub
Command1_Click()
If
Command1Caption
=
"抽奖"
Then
Command1Caption
=
"停止"
Timer1Enabled
=
True
Else
Timer1Enabled
=
False
Command1Caption
=
"抽奖"
End
If
End
Sub
Private
Sub
Form_Load()
Command1Caption
=
"抽奖"
Timer1Interval
=
50
Timer1Enabled
=
False
End
Sub
Private
Sub
Timer1_Timer()
Randomize

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。
command1用来随机抽取,text2显示
text1用来自己输入
command2用来判断
基本思想:假设连续有a位相同,经过验证如果为真则得出结果,如果为假,则假设a=a-1位相同……直到a=0
也可以自己输入text2数据来检验程序
这段程序不局限于7位数
Private Sub Command2_Click()
Dim a$, b$, i%, j%, k%
a = CStr(Text1)
b = CStr(Text2)
For i = Len(a) To 1 Step -1
For j = 1 To Len(a) - i + 1
If Mid(a, j, i) = Mid(b, j, i) Then
k = i
Exit For
End If
Next
If k <> 0 Then Exit For
Next
Print k, Mid(a, j, i)'输出相同位数和相同数字
If len(a)+1-k>5 Then
MsgBox "对不起,无奖项"
Else
MsgBox Len(a) + 1 - k & "等奖"'判断奖项
End If
End Sub
Private Sub Command1_Click()
a = CStr(Text1)
Text2 = 10 ^ (Len(a) - 1) + Int(Rnd 09 10 ^ Len(a))
End Sub
