VB编程~~填空题~~~帮忙~~谢谢!
下面程序的功能是输入一个字符串,统计其中包含的字母,数字和其他字符的个数,并输出.
Private Sub Command1-Click()
Dim str1 As String
Dim i As Integer
Dim n1 As Integer,n2 As Integer,n3 As Integer
n1:字母的个数;n2:数字的个数;n3:其他字符的个数
str1=InputBox("请输入任意串","字符统计")
For i=1to Len(Str1)
Select Case----------------
Case"A"To"Z","a"To"z"
n1=n1+1
Case Else
----------------
End Select
Next i
在----------处填写 程序代码!!
Private Sub Command1_Click()
Dim str1 As String
Dim i As Integer
Dim n1 As Integer, n2 As Integer, n3 As Integer
'n1:字母的个数;n2:数字的个数;n3:其他字符的个数
str1 = InputBox("请输入任意串","字符统计")
For i=1 To Len(Str1)
Select Case Mid(Str1, i, 1)
Case"A" To "Z", "a" To "z"
n1 = n1 + 1
Case Else
If Mid(str1, i, 1) > "0" And Mid(str1, i, 1) < "9" Then
n2 = n2 + 1
Else
n3 = n3 + 1
End If
End Select
Next i 。
答：1、j>=i2、j-i3、document.write(vbcrlf)详情>>
