How can I display the items stored in the above map on the console?

推荐答案

这取决于您要如何显示它们，但是您始终可以轻松地对其进行迭代:

Well it depends on how you want to display them, but you can always iterate them easily:

typedef map<string, list<string>>::const_iterator MapIterator;
for (MapIterator iter = mapex.begin(); iter != mapex.end(); iter++)
{
    cout << "Key: " << iter->first << endl << "Values:" << endl;
    typedef list<string>::const_iterator ListIterator;
    for (ListIterator list_iter = iter->second.begin(); list_iter != iter->second.end(); list_iter++)
        cout << " " << *list_iter << endl;
}
