相当于
Label1.Text = Label1.Text a(i,j) " "
1。不能,语法问题。
2。“ ”中包含的是空格,这句话相当于将数组a中的所有数据罗列出来,空格是分隔符,没有它数据就连在一起了,你没法区分了!
vb.net怎么随机生成5个不同是数(1-33内的数),大神求救
想要生成多少个都行。
Randomize()随机打乱
dim a1 as integer=cint(rnd()*32))+1
dim a2 as integer=cint(rnd()*32))+1
dim a3 as integer=cint(rnd()*32))+1
dim a4 as integer=cint(rnd()*32))+1
dim a5 as integer=cint(rnd()*32))+1
vb.net程序,利用随机函数产生100个1到100之间的整数,求其中的最大最小值。
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Randomize() '产生随机数种子 以防止每次生成结果都一样
Dim a(100) As Integer '声明数组存放数据 用来保存随机数结果
Dim max As Integer, min As Integer '声明两个变量存最大值和最小值
min = 1000 : max = 0 '设置初值
For i = 0 To 99 '循环100次
a(i) = Int(Rnd() * 1000 + 1) '用rnd生成一个随机数 由于rnd范围为0-1之间的小数.所以*1000设置他的范围为0到999之间 加1变成1到1000之间
If a(i) = max Then max = a(i) '如果当前数值大于最大值的变量就保存
If a(i) = min Then min = a(i) '如果当前数值小于最小值的变量就保存
Next
MsgBox("最大值为" max)
MsgBox("最小值为" min)
End Sub
vb.net 随机出数字,但要求包含特定数字如何做?
下面是你需要的,经过三次随机,可以看一下,直接调用函数返回一个字符就是你要的,看不懂再追问哈
Structure jiqi
Dim num As Integer
Dim num2 As Integer
End Structure
Public Function chansheng() As String
Dim str As String = ""
Dim n As Integer = 0
Dim p68 As Integer
Randomize()
p68 = Int(Rnd() * 2) + 1
Dim a(10), b(8) As Integer
For i = 1 To 6
b(i) = i - 1
Next
b(7) = 7
b(8) = 9
For i = 1 To 6
Randomize()
a(i) = b(Int(Rnd() * 8) + 1)
Next
If p68 = 1 Then
For i = 7 To 10
a(i) = 6
Next
ElseIf p68 = 2 Then
For i = 7 To 10
a(i) = 8
Next
End If
Dim c(10) As Integer
Dim temp As jiqi
Dim pi(10) As jiqi
For i = 1 To 10
pi(i).num = a(i)
pi(i).num2 = Int(Rnd() * 1000) + 10
Next
For i = 1 To 10
For j = 1 To 10 - i
If pi(j).num2 pi(j + 1).num2 Then
temp = pi(j + 1)
pi(j + 1) = pi(j)
pi(j) = temp
End If
Next j
Next i
For i = 1 To 10
str = str pi(i).num
Next
Return str
End Function
怎么用vb.net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
