How to print out a found element from a STL List inside of a map?

Question

void Cinema::movieRunningAt(Movie& m, std::list<int>& movieList)
{

    map<const Movie*, std::list<int>>::iterator mov_it;
    mov_it = movie_times.find(&m);

    if (mov_it == movie_times.end())
    {
        cout << "No movie was found" << endl;
        return;
    }
    cout << mov_it->second << endl;
}

second is a list, so how do I print the found element out?

cout << mov_it->second << endl;

?

Answer 1

mov_it->second is a list container print it element need again traverse
Examples are as follows

map<int, list<int>> mapContainer{ {1, {1,2,3}}, {2, {2, 3, 4}} };
map<int, list<int>>::iterator it = mapContainer.find(1);
if (it != mapContainer.end())
{
    for (int element : it->second)
    {
        cout << element << endl;
    }
}
