我可以在C++中比较两个结构吗？

#include <iostream>

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

bool operator==(const Person& p1, const Person& p2) {
    return p1.name == p2.name && p1.age == p2.age;
}

int main() {
    Person person1 = {"Alice", 20};
    Person person2 = {"Bob", 25};
    Person person3 = {"Alice", 20};

    if (person1 == person2) {
        std::cout << "person1 and person2 are equal" << std::endl;
    } else {
        std::cout << "person1 and person2 are not equal" << std::endl;
    }

    if (person1 == person3) {
        std::cout << "person1 and person3 are equal" << std::endl;
    } else {
        std::cout << "person1 and person3 are not equal" << std::endl;
    }

    return 0;
}

person1 and person2 are not equal
person1 and person3 are equal
