声明和使用静态列表以打印对象(在c++中)

class Person {
public:
    std::string name;
    int age;
};

class Person {
public:
    std::string name;
    int age;

    static std::vector<Person> personList;
};

std::vector<Person> Person::personList;

class Person {
public:
    std::string name;
    int age;

    static std::vector<Person> personList;

    static void printPersonList() {
        for (const auto& person : personList) {
            std::cout << "Name: " << person.name << ", Age: " << person.age << std::endl;
        }
    }
};

int main() {
    Person p1;
    p1.name = "Alice";
    p1.age = 25;

    Person p2;
    p2.name = "Bob";
    p2.age = 30;

    Person::personList.push_back(p1);
    Person::personList.push_back(p2);

    Person::printPersonList();

    return 0;
}
