How to use c++ unique_ptr with the map container?

Question

Is it possible to use the unique_ptr with the map container? For example,

#include<iostream>
#include<string>
#include<map>
#include<memory>
using namespace std;

int main(){
    
    unique_ptr<map<string, int>> person;
    person = make_unique<map<string, int>>(make_pair("Tom", 34));

    cout << (*person)["Tom"] << endl;  
}

Answer 1

How about defining:

#include<iostream>
#include<string>
#include<map>
#include<memory>
using namespace std;

int main(){
    unique_ptr<map<string, int>> person(new map<string, int>); 
    (*person)["Tom"] = 34;

    cout << (*person)["Tom"] << endl;  
}

Output is:

34
