c++定义一个教师类和一个学生类二者有一部分数据成员是相同的例如 numnamesex。请编程将一个学生类对象转换为教师类只将以上 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的数据的一部分。

#include #include using namespace std;

class Student { public: int num; string name; char sex; int age; void display() { cout << "num: " << num << endl; cout << "name: " << name << endl; cout << "sex: " << sex << endl; cout << "age: " << age << endl; } };

class Teacher { public: int num; string name; char sex; int salary; void display() { cout << "num: " << num << endl; cout << "name: " << name << endl; cout << "sex: " << sex << endl; cout << "salary: " << salary << endl; } };

int main() { Student s; s.num = 1001; s.name = "Tom"; s.sex = 'M'; s.age = 18; s.display();

Teacher t;
t.num = s.num;
t.name = s.name;
t.sex = s.sex;
t.salary = 5000;
t.display();

return 0;
