vb 生成20个1到100之间的随机数,统计其中的1位数,2位数,3位数的个数

privatesubcommand1_click()dima(1to10)asinteger,i,jfori=1to10a(i)=int(rnd*100)+1printa(i);nextprintfo

PrivateSubCommand1_Click()Dima(9)AsIntegerFori=0To9way1:Randomizea(i)=Int(Rnd()*10)+1Ifi>1ThenForp=0

窗体中加命令按钮,单击事件代码如下：PrivateSubCommand1_Click()  Randomize  Dima(1To20)AsInteger&nb

Private Sub Command1_Click()Text1.Text = ""Dim A(1 To 1

Dimb(100)PrivateSubCommand1_Click()Fori=1To100a=Int(1800*Rnd)+200b(i)=aPrintb(i)NextiEndSubb这个数组里面就保

先在窗体上添加一个TextBox文本框（将其Multiline属性设置为True,并调整宽高以便能较好的显示出100个随机数）和一个Button按钮.然后双击Button按钮跳转到代码编辑窗口,粘帖以

1填写imod6=0,指的是余数要等于0；2填写S,表示要把S输出.

前些天我才写的,是给别人弄的,他要的是1到100的十个数,并且按command2可以到换,我稍加修改给你(别忘了把窗体拉长点哈!短了后面不能显示哦)还要添加一个commandPrivateSubCom

PrivateSubCommand1_Click()RandomizeFori=1To20a=Int(Rnd()*21+30)Printa;IfiMod4=0ThenPrintNextEndSub这里

PrivateSubCommand1_Click()Dimoushu%,danshu%,sum%oushu=0danshu=0Fori=1To10Randomizesum=Int(Rnd*100)If

1)t=a(i)这句下标越界了,因为这时i=112)判断素数的语句也有点逻辑上的错误.3)随机数有可能重复.我改了下,请参考：PrivateSubForm_Click()Dima(1To10),iAs
