请教大侠一个问题
任意输入一个n，计算n!以及其总和 (例如1！+2！+3！+...n!)
用子过程方法
我编写的代码如下，但算出来的结果却是错的，不知道问题出在哪里，百思不得其解，请教大侠指出，万谢！
Private Sub calcmd_Click()
Dim i As Integer, j As Integer
Dim s As Double, p As Double
i = Val(Text1.Text)
s = 0
For j = 1 To i
Call fac(i, p)
s = s + p
Next j
Label3.Caption = s
End Sub
Sub fac(a As Integer, b As Double)
Dim c As Integer
b = 1
For c = 1 To a
b = b * c
Next c
End Sub
Private Sub calcmd_Click()Dim i As Integer, j As IntegerDim s As Double, p As Doublei = Val(Text1.Text)s = 0For j = 1 To iCall fac(j, p) '只要修改此处即可。s = s + pNext jLabel3.Caption = sEnd SubSub fac(a As Integer, b As Double)Dim c As Integerb = 1For c = 1 To ab = b * cNext cEnd Sub...
