1,逆序数告拆计算磨友迟
Private Function ReversOrder(ByVal InStr As String) As Long
Dim i As Integer, j As Integer, c As Long
Dim n() As Integer
ReDim n(Len(InStr))
For i = 1 To Len(InStr)
n(i) = Val(Mid(lnStr, i, 1))
For j = 1 To i - 1
If n(i) n(j) Then
c = c + 1
End If
Next j
Next i
ReversOrder = c
End Function
2. 级数有限项求和
Private Sub Command1_click()
n = 0
For i = 1 To 100 '1 到100 项,你可改为你的项数
n = n + 1 / i '对级数的前100项求和:1/1+1/2+1/3+1/4...+1/100,你可改成你的级数
Next i
Text1.Text = Str(n) '在textbox里显示结果
End Sub
Private Sub Form_Click()
Dim sum#, n#, i#, sign%
sum = 0: n = 1: i = 1: sign = 1
Do
sum = sum + n
i = i + 3
sign = -sign
n = sign / i
Loop Until n 0.01
Print "级数猜搭求和得结果庆兆迟为誉李S=" sum
End Sub
