Problem A: 薪酬计算

Description

某公司有经理（Manager）、雇员（Employee）、小时工（HourlyWorker）和营销人员（CommWorker）四类员工（Person），他们的薪酬计算方法各不一样：
Manager采用年薪制；
Employee按月计酬，方法是：月基本工资+奖金，奖金是指奖励几个月工资；
HourlyWorker是按工作时间计酬，方法是：工作小时*每小时工资；
CommWorker按月计酬，方法是：月基本工资+年销售额的2%；
由于每类员工（Person）的工资输入（input函数）、工资计算办法（pay函数）、显示信息（show函数）均不一样，因此使用多态来实现。

请仔细阅读append.cc代码，并设计并实现这个员工类的派生体系，使main()函数能够运行并得到正确的输出。

Input

输入的第一个整数n，表示用n组测试样例。
每组测试样例占一行，分别为员工职位、员工姓名、基础工资base、附加项k（Manager无此项）。
员工职位为Manager，其base为年薪，单位为千元；
员工职位为Employee，其base为月薪，单位为千元，附加项为奖励k个月的工资；
员工职位为HourlyWorker，其base为时薪，单位为元，附加项为年工作k个小时；
员工职位为CommWorker，其base为月薪，单位为千元，附加项是年销售额k千元；

Output

按格式输出每个人的姓名、职位和最终计算的年薪，详细格式见sample。

Sample Input

6
Manager Zhang3 200
Employee Li4 8 5
Employee Wang5 10 3
HourlyWorker Zhao6 45 650
CommWorker Liu7 5 300
CommWorker Sun8 6 180

Sample Output

Zhang3 (Manager) Annual Salary is 200000.
Li4 (Employee) Annual Salary is 136000.
Wang5 (Employee) Annual Salary is 150000.
Zhao6 (HourlyWorker) Annual Salary is 29250.
Liu7 (CommWorker) Annual Salary is 66000.
Sun8 (CommWorker) Annual Salary is 75600.
