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!
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
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
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
