使用RTTI获取/设置子属性

#include <iostream>
#include <string>

class Person {

    void set_name(const std::string& name) { this->name = name; }
    void set_age(int age) { this->age = age; }
    void set_gender(const std::string& gender) { this->gender = gender; }

    std::string get_name() const { return name; }
    int get_age() const { return age; }
    std::string get_gender() const { return gender; }

private:
    std::string name;
    int age;
    std::string gender;
};

int main() {
    Person person("Alice", 30, "female");

    std::cout << "Name: " << person.get_name() << std::endl;
    person.set_name("Bob");
