设计person类，包括私有数据成员：姓名、性别和年龄；设计类teacher继承person类，新增私有数据成员：工资；设计student类继承person类，新增私有数据成员：成绩。要求每个类中的数据通过构造函数进行初始化。在主函数中分别定义一个teacher类和student类的对象，并输出这两个对象的值

以下是对应的代码实现：

#include <iostream>
#include <string>

using namespace std;

class Person {
private:
    string name;
    string gender;
    int age;
public:
    Person(string n, string g, int a) : name(n), gender(g), age(a) {}
    void showInfo() {
        cout << "Name: " << name << endl;
        cout << "Gender: " << gender << endl;
        cout << "Age: " << age << endl;
    }
};

class Teacher : public Person {
private:
    int salary;
public:
    Teacher(string n, string g, int a, int s) : Person(n, g, a), salary(s) {}
    void showInfo() {
        Person::showInfo();
        cout << "Salary: " << salary << endl;
    }
};

class Student : public Person {
private:
    int score;
public:
    Student(string n, string g, int a, int s) : Person(n, g, a), score(s) {}
    void showInfo() {
        Person::showInfo();
        cout << "Score: " << score << endl;
    }
};

int main() {
    Teacher t("Tom", "Male", 35, 5000);
    Student s("Lucy", "Female", 18, 90);

    cout << "Teacher's Info:" << endl;
    t.showInfo();
    cout << endl;

    cout << "Student's Info:" << endl;
    s.showInfo();

    return 0;
}

输出结果：

Teacher's Info:
Name: Tom
Gender: Male
Age: 35
Salary: 5000

Student's Info:
Name: Lucy
Gender: Female
Age: 18
Score: 90
