C++习题 对象转换

[Submit][Status][Web Board]

Description

定义一个Teacher(教师)类(教师号,姓名,性别,薪金)和一个Student(学生)类(学号,姓名,性别,成绩),二者有一部分数据成员是相同的,num(号码),name(姓名),sex(性别)。编写程序,将一个Student对象(学生)转换为Teacher(教师)类,只将以上3个相同的数据成员移植过去。可以设想为: 一位学生大学毕业了,留校担任教师,他原有的部分数据对现在的教师身份来说仍然是有用的,应当保留并成为其教师数据的一部分。

Input

一个教师的信息和一个学生的信息

Output

学生的信息和学生转换为教师后的信息

Sample Input

10001 Li f 1234.520010 Wang m 89.5

Sample Output

student1:num:20010name:Wangsex:mscore:89.50teacher2:num:20010name:Wangsex:mpay:1500.00
