I grew up in New Hampshire, a small town in South Canada, where in my father’s words for the seasons were “Spring, Summer, Fairtime and Winter!” At that time, a week-long fair was held in the town every autumn. Thousands of people from other towns came to sell and buy things. It was the busiest time of the year.

When “Fairtime” came, my grandma became the most “useful” and busiest person of the family. Grandma was a kind, well-educated old lady. She was good at cooking. All her rrelatives liked the foodshe cooked. During “fairtime”, they would come to live in her house and have meals there. Grandma was always happy to look after them.

Year after year, many people moved to big cities. There was no loner “Fairtime”. Grandma became very old and was gradually going blind. My parents and I moved to live with Granma in her house. We did our best to make her day-to-day life as comfortable as possible. I was at high school then. What I often did at home was to help Grandma with the daily newspaper’s crossword puzzle. However, she didn’t look happy. She often sat in her room for hours, without saying a word.

To attract people to move back, the Town Hall decided to reopen the Fair. One day, when I came back room school, I saw Grandma wearing her glasses, washing the dishes in the kitchen. With a big smile on her face, she looked a lot much younger. She told me that her two nieces would come. “They said the food I cooked was very delicious and they want to stay in my house again.” Grandma said happily. “They will stay here for one week and we can have a big party. That must be the busiest week I’ve had in years!”

I suddenly realized that Grandma didn’t want to be looked after. She wanted to be “useful”, appreciated and helpful.

阅读以下说明和C++代码，填补C++代码中的空缺，将解答写在对应栏内。
[说明]
已知某公司按周给员工发放工资，其工资系统需记录每名员工的员工号、姓名、工资等信息。其中一些员工是正式的，按年薪分周发放(每年按52周计算)；另一些员工是计时工，以小时工资为基准，按每周工作小时数核算发放。
下面是实现该工资系统的C++代码，其中定义了4个类：工资系统类PayRoll、员工类Emplovee、正式工类Salaried和计时工类Hourly，Salaried和Hourly是Employee的子类。
