C++将一个对象写入一个文件,然后再将其读入？

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

    Person(std::string name, int age) : name(name), age(age) {}
};

#include <fstream>

int main() {
    Person person("John", 30);

    std::ofstream outfile("person.bin", std::ios::binary);
    outfile.write(reinterpret_cast<const char*>(&person), sizeof(Person));
    outfile.close();

    return 0;
}

#include <fstream>

int main() {
    Person person;

    std::ifstream infile("person.bin", std::ios::binary);
    infile.read(reinterpret_cast<char*>(&person), sizeof(Person));
    infile.close();

    std::cout << "Name: "<< person.name << ", Age: "<< person.age<< std::endl;

    return 0;
}
