    "Who needs  a  shopping mall (购物中心 ) if you have Taobao?" says Wang Lin,28,a writer in

Beijing. Taobao ,China's largest online shopping site(网上购物网站),has become an important part

of Wang Lin's life. She spends lots of money on Taobao. A growing number of Chinese Internet users

like Wang have found the joys of online shopping. Most online shoppers are students or young workers. More women shop on line than men. Clothing and home-use products are the most popular on line. It

was reported that more than 250 billion yuan, was spent on online shopping last year,80% through

Taobao. Taobao means "looking for treasure" in Chinese. People can find almost everything they need

on Taobao,from clothes to books,from candies to DVD players. " You may question the security of

online shopping," Wang Lin said,"It's very safe and convenient. Unless you receive the products from

the sellers and are satisfied with them,the shop owner will not get the money. You can also get your

money back if you want to return the products. "

【说明】
本应用程序的运行窗口如图2所示。

窗口中的3个文本框和两个按钮名称分别为Txt_salary、Txt_base、Txt_tax、Cmd_compute和Cmd_quit。运行时，文本框Txt_base存放的是免税金额基数(应扣除的基本费用co)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，方法是：以每月收入总额减去免税金额基数后的余额作为该月的月应纳税所得额，再将应纳税所得额按相应级数采用相应的税率进行累进计算。目前的免税金额基数为800元，税率如表1所示。

级数	月应纳税所得额	适用税率(%)
1 2 3 4 5 6 7 8 9	不超过500元的部分 501元～2000元的部分 2001元～5000元的部分 5001元～20000元的部分 20001元～40000元的部分 40001元～60000元的部分 60001元～80000元的部分 80001元～100000元的部分 超过100000元的部分	5 10 15 20 25 30 35 40 45

设一个人的月应纳税所得额为K(元)，用下面的公式计算其应缴纳的个人所得税额S (元)；
若0＜K≤500，则S=K×5%；
若500＜K≤2000，则S=500×5%+(K-500)×10%；
若2000＜K≤5000，则S=500×5%+1500×10%+(K-2000)×15%；
若5000＜K≤20000，则S=500×5%+1500×10%+3000×15%+(K-5000)×20%；
例如，某人某月工资总额为4100元，减去800元后，应纳税所得额为3300元，其应缴纳的个人所得税额为500*5%+1500*10%+1300*15%=370元。
在开发过程中，需要编写的程序代码如下；
