如何在C++中序列化对象？

#include<boost/archive/binary_iarchive.hpp>
#include<boost/archive/binary_oarchive.hpp>
#include<boost/serialization/string.hpp>
#include <fstream>

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

    // 序列化函数
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version) {
        ar & name;
        ar & age;
    }
};

int main() {
    // 创建一个Person对象
    Person person;
    person.name = "John";
    person.age = 30;

    // 将对象序列化为二进制文件
    std::ofstream ofs("person.bin");
    boost::archive::binary_oarchive oa(ofs);
    oa<< person;
    ofs.close();

    // 从二进制文件反序列化对象
    Person new_person;
    std::ifstream ifs("person.bin");
    boost::archive::binary_iarchive ia(ifs);
    ia >> new_person;
    ifs.close();

    return 0;
}
