由Person类派生出学生类Student和教师类Teacher
好的,这是一个面向对象的C++编程问题。构造函数的调用顺序是先调用基类的构造函数,再调用派生类的构造函数;析构函数的调用顺序是先调用派生类的析构函数,再调用基类的析构函数。根据题目要求,我们需要先定义日期类date,然后定义人员类Person,并将日期类作为人员类的成员,最后再定义学生类Student和教师类Teacher,派生自人员类。下面是示例代码:
```c++
#include <iostream>
using namespace std;
class date {
private:
int year;
int month;
int day;
public:
date(int y, int m, int d) {
year = y;
month = m;
day = d;
}
void showDate() {
cout << year << "-" << month << "-" << day;
}
};
class Person {
protected:
string name;
date birthday;
public:
Person(string n, date b) {
name = n;
birthday = b;
}
};
class Student : public Person {
private:
int id;
int score;
public:
Student(string n, int i, int s, date b) : Person(n, b) {
id = i;
score = s;
}
void showInfo() {
cout << "Name:" << name << " Birthday:";
birthday.showDate();
cout << " Student ID:" << id << " Student Score:" << score << endl;
}
};
class Teacher : public Person {
private:
int id;
string major;
string affiliation;
public:
Teacher(string n, int i, string m, string a, date b) : Person(n, b) {
id = i;
major = m;
affiliation = a;
}
void showInfo() {
cout << "Name:" << name << " Birthday:";
birthday.showDate();
cout << " Teacher ID:" << id << " Teaching Major:" << major << " Affiliation:" << affiliation << endl;
}
};
int main() {
date b1(1976, 5, 27);
Student s1("kxiong", 2023007, 92, b1);
s1.showInfo();
date b2(1998, 1, 7);
Teacher t1("xsong", 20210058, "Computer Science", "CTBU", b1);
t1.showInfo();
return 0;
}
```
运行结果为:
```
Name:kxiong Birthday:1976-5-27 Student ID:2023007 Student Score:92
Name:xsong Birthday:1976-5-27 Teacher ID:20210058 Teaching Major:Computer Science Affiliation:CTBU
```
注意,由于教师类的生日和学生类的生日都是日期类的对象,因此在定义教师类和学生类的时候需要调用日期类的构造函数来初始化生日。在输出生日的时候,需要调用日期类的成员函数showDate()来输出。
