打开VB软件，在command中进行编译，程序如下：

当n=23时，
Private Sub Command1_Click()
Dim n As Byte
n = 23
Const er As Byte = 2
Dim returnS As String
Dim shang As Byte
Dim yushu(1 To 5) As Byte
Dim i As Byte
i = 5
shang = n \ er
yushu(i) = n Mod er
returnS = yushu(i)
While shang <> 0
i = i - 1
n = shang
shang = n \ er
yushu(i) = n Mod er
returnS = yushu(i) & returnS
Wend

Print yushu(1); yushu(2); yushu(3); yushu(4); yushu(5)
End Sub

当n=230时，

Private Sub command1_click()
Me.Font.Size = 30
Print erjinzhi(230)
End Sub

Private Function erjinzhi(m As Byte) As String
Dim n As Byte
n = m
Const er As Byte = 2
Dim returnS As String

Dim shang As Byte
Dim yushu(1 To 8) As Byte
Dim i As Byte
i = UBound(yushu)
shang = n \ er
yushu(i) = n Mod er
returnS = returnS & yushu(i)

While shang <> 0
i = i - 1
n = shang
shang = n \ er
yushu(i) = n Mod er
returnS = yushu(i) & returnS
Wend

erjinzhi = returnS


End Function
