以下是VB编程语言的实现示例:
'定义变量,存储每个奖项的人数
Dim firstPrize As Integer = 3
Dim secondPrize As Integer = 5
Dim thirdPrize As Integer = 12
Dim souvenirPrize As Integer = 10
'定义变量,存储抽奖结果
Dim firstPrizeList As New List(Of Integer)
Dim secondPrizeList As New List(Of Integer)
Dim thirdPrizeList As New List(Of Integer)
Dim souvenirPrizeList As New List(Of Integer)
'定义变量,存储编号滚动的起始编号
Dim currentNum As Integer = 1
'循环抽取各种奖项
For i As Integer = 1 To firstPrize
firstPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To secondPrize
'抽取二等奖,并将编号添加到二等奖名单中
secondPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To thirdPrize
'抽取三等奖,并将编洞派号添加到三等奖名单中
thirdPrizeList.Add(currentNum)
currentNum += 1
Next
For i As Integer = 1 To souvenirPrize
'抽取纪念奖,并将编纳档贺号添加到纪念奖名单中
souvenirPrizeList.Add(currentNum)
currentNum += 1
Next
'输出抽奖结果
Console.WriteLine("一等奖名单:" &String.Join(",", firstPrizeList))
Console.WriteLine("二等奖名单:" &String.Join("蠢凯,", secondPrizeList))
Console.WriteLine("三等奖名单:" &String.Join(",", thirdPrizeList))
Console.WriteLine("纪念奖名单:" &String.Join(",", souvenirPrizeList))
Dim n As IntegerDim a()
Private Sub Command1_Click()
If n = 0 Then'塌亏第点击执行
m = Val(Text1)
ReDim a(1 To m)
For i = 1 To m '数组a元素1至mm数
a(i) = i
Next
For i = 1 To m - 1 '随机打乱数组a元素
r = Int(Rnd * m + 1)
tmp = a(i)
a(i) = a(r)
a(r) = tmp
Next
End If
n = n + 1 '计数点击数
If n >Val(Text1) Then'数超指定数抽奖结束
MsgBox "乱宽抽奖结束"
Exit Sub
End If
Text2 = a(n) '数组抽第n数哗衫亮由于数组随机排列所相于随机数并且重复
End Sub
在定义函数时有时在语句前,有的在语句后。希望能帮到你!
