在结构中重载ostream和istream时使用逗号分隔

#include <iostream>

struct Person {
    std::string name;
    int age;
};

// 重载输出运算符
std::ostream& operator<<(std::ostream& os, const Person& person) {
    os << "Name: " << person.name << ", Age: " << person.age;
    return os;
}

// 重载输入运算符
std::istream& operator>>(std::istream& is, Person& person) {
    std::cout << "Enter name: ";
    is >> person.name;
    std::cout << "Enter age: ";
    is >> person.age;
    return is;
}

int main() {
    Person person;
    
    std::cout << "Enter person details (name, age): ";
    std::cin >> person;

    std::cout << "Person details: " << person << std::endl;

    return 0;
}
