 work8:

 1.两层while循环，外层的while循环，让用户输入用户名、密码、工作了几个月、每月的工资（整数），

 用户名或密码为空，或者工作的月数不为整数，或者月工资不为整数，则重新输入

 2.认证成功，进入下一层while循环，打印命令提示，有查询总工资，查询用户身份

 （如果用户名为alex则打印super user，如果用户名为yuanhao或者wupeiqi

 则打印normal user，其余情况均打印unkown user），退出功能

 3.要求用户输入退出，则退出所有循环（使用tag的方式）

 运行效果如下：

 user: egon

 password: 123

 work_mons: 12

 salary: 10000

             1 查询总工资

             2 查询用户身份

             3 退出登录

 >>: 1

 总工资是: 120000.0

             1 查询总工资

             2 查询用户身份

             3 退出登录

 >>: 2

 unkown user

             1 查询总工资

             2 查询用户身份

             3 退出登录

 >>: 3
