vb点虐 产生随机数组 vb 随机数

编写一个 VB.NET 程序,产生 100 个 100 以内的随机数,将他们从大到小排序后输出

Private Sub Command1_Click()

Dim a(1 To 100) As Integer

Dim i As Integer, j As Integer, k As Integer

For i = 1 To 100 '给数组a一百个元素赋值,并换每行十个数字输出来窗体上

a(i) = Int(Rnd * 101)

k = k + 1

Print Tab((k - 1) * 5); a(i);

If k = 10 Then k = 0: Print

Next i

Print

Print

For i = 100 To 2 Step -1 '用冒泡排序法对数组进行排序

For j = 1 To i - 1

If a(j) a(j + 1) Then

t = a(j): a(j) = a(j + 1): a(j + 1) = t

End If

Next j

Next i

For i = 1 To 100 '输出排好序的数组

k = k + 1

Print Tab((k - 1) * 5); a(i);

If k = 10 Then k = 0: Print

Next i

End Sub

vb点虐 产生随机数

方法名称:next();功能描述:返回一个0~2147483647之间的整数

方法名称:next(i);功能描述:返回一个0~i之间的整数

方法名称:next(i,j);功能描述:返回一个i~j之间的整数

方法名称:Nextdouble();功能描述:返回一个0~1之间的随机小数

================

使用方法:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim rand = New System.Random()

MsgBox(rand.next().ToString())

End Sub

==========================

产生N个不同数的话,我给你个我写的VB的代码,你稍微改下:

产生0-10的数:

Private Sub Command1_Click()

Randomize

Dim a(10) As Long

n = 10

For i = 0 To n

a(i) = Int(Rnd() * (n + 1))

For j = 0 To i - 1

If a(i) = a(j) Then

i = i - 1

Exit For

End If

Next

Next

For i = 0 To n

Print a(i)

Next

End Sub

怎么用vb点虐 随机产生5个不同的数,范围1-33,求帮忙改一下

Private Sub Command1_Click()

Dim num(6) As Integer

Dim i As Integer, j As Integer

Dim tmp As Integer

Randomize '防止每次生出随机数一样

For i = 0 To 5

num(i) = Int(Rnd * 53) + 1

Next

PrintNum "新生成的6个随机数为:", num()

For i = 0 To 5

For j = 0 To 5

If num(j) num(j + 1) Then

tmp = num(j)

num(j) = num(j + 1)

num(j + 1) = tmp

End If

Next

Next

PrintNum "排序后的6个随机数为:", num()

End Sub
