[应用说明9]
本应用程序的运行窗口如图2-6所示。
窗口中的3个文本框和2个按钮,名称分别为Txt_salary,Txt_base,Txt_tax,Cmd compute和Cmd_quit。运行时,文本框Txt_base中存放的是免税金额基数(应扣除的基本费用)。当用户在文本框Txt_salary中输入月收入(工资或薪金)并单击“计算”按钮 Cmd_compute后,Txt_tax框中就显示计算所得的应纳税额。文本框Txt_base和Txt_ tax在运行时不接受用户输入,Txt_base的内容以灰色显示。
个人工资(或薪金)所得税是按照超额累进的税率来征收的,其计算方法参考试题8。

Option Base 0
Private Sub Cmd_compute_Click()
Dim paylevel,taxPrate
paylevel=Array(0,500,2000,5000,20000,40000,60000,80000,100000,1000001)
taxPrate=Array(5,10,15,20,25,30,35,40,45)
K=(1)
S=0
if(K>0) Then
For j=1 TO 9
If (2) Then
S=S+(paylevel(j)-paylevel(j-1)) * taxPrate(j-1)/100
Else
S=S+((3) ) * taxPrate(j-1)/100
Exit For
End If
Next j
End If
(4)=Str$(S)
End Sub
