求C语言编程，急切

工资纳税系统编程：
个人所得税每月交一次，底线是1600元/月，也就是超过了1600元的月薪才开始计收个人所得税。个人所得税税率表一（工资、薪金所得适用）
级数----------全月应纳税所得额----------税率（％）
1--------------不超过500元的--------------------------5
2----------超过500元至2000元的部分------------10
3----------超过2000元至5000元的部分----------15
4----------超过5000元至20000元的部分---------20
5----------超过20000元至40000元的部分-------25
6----------超过40000元至60000元的部分-------30
7----------超过60000元至80000元的部分-------35
8----------超过80000元至100000元的部分------40
9----------超过100000元的部分---------------------45
表中的应纳税所得额是指以每月收入额减除1600元后的余额。
例如：计算为：2500-1600=900
应纳个人所得税额=500×5%+400×10% =65
再比如：我们用一个大额工资计算，25000元
应纳税所得额=25000-1600=23400
应纳个人所得税税额=500×5%+1500×10%+3000×15%+15000×20%+3400×25%=4475
要求：
（1）职工信息输入、修改、查询；
（2）职工工资录入；
（3）计算出纳税金额；
（4）按工资排序输出所有职工工资报表；
（5）输入职工代号，输出个人工资条；

有个程序但老出错，麻烦哪位大鸟看看那：
