C++ 学生类转换为教师类：保留共同数据成员

#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;
