how to print elements of a vector of type Person class in c++

I created a class called person with two members name and age then I created two objects of that

class p1 and p2 and then I added them to a vector. I tried then to print them but could not.

this my code:

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



int main(){
    Person p; 
    vector <Person> vector; 
    p.name = "Vitalik"; 
    p.age = 29; 
    Person p2; 
    p2.name = "Bueterin"; 
    p2.age = 50; 
    vector.push_back(p); 
    vector.push_back(p2); 
    
    for(int i = 0; i < vector.size(); i++){
        cout << vector[i] << endl; 
    }

    

    return 0; 
}

I tried multiple ways to loop through the vector and print the elements but I keep getting this message:

 error: invalid operands to binary expression ('std::ostream' (aka 'basic_ostream<char>') and 'std::__vector_base<Person, std::allocator<Person> >::value_type' (aka 'Person'))
        cout << vector[i] << endl; 

>Solution :

You can implement operator<< or just write something like this:

cout << vector[i].name << ": " << vector[i].age << endl;

cout doesn’t know how to print this object by default.
