多位数乘一位数

1.新建一个按钮和两个Textbox，并把按钮改为‘乘法’

2.双击按钮，输入以下：

Private Sub 乘法_Click()

Dim c As Byte

Dim a() As Byte

Dim b As String

Dim changdu As Long, i As Long

changdu = Len(Text1.Text)

ReDim a(changdu)

For i = 1 To changdu

b = Mid(Me.Text1.Text, i, 1)

a(i) = Int(Val(b))

Next i

b = Me.Text2.Text

c = Int(Val(b))

Dim rm As Byte

Dim r() As Byte

ReDim r(changdu)

Dim d As Byte

For i = changdu To 1 Step -1

rm = a(i) * c + d

r(i) = rm Mod 10

d = rm \ 10

Next i

If d <> 0 Then

Print d

End If

For i = 1 To changdu

Print r(i)

Next i

End Sub

3.运行该程序，输入想要计算的数字

4.点击运行按钮即可
