    Is this a 'medium difficulty' problem?

    ostream& operator<<(ostream& os, const Person& p) {
    os << "first_name=" << p.get_first_name() << ",last_name=" << p.get_last_name();
    return os;
}

    Shouldn't the overloaded << operator function be declared as a friend of class Person, so that it can access the private data within a Person object?

    std::ostream &operator<<(std::ostream &out, const Person &p){
    out << "first_name=" + p.get_first_name() << "," << "last_name=" + p.get_last_name();
    
    return out;
}
