When using mapvariable[somekey] = somevalue to insert into a map variable, how to check whether there is conflicting key value in the map in an elegant way?

// An empty map.
map<cstring,cstring> TempMap;

// If you lookup a for a key which is not present,
// it will create empty entry and return. It won't
// throw any error.
CString LookupKey = _T("key"); // Key which is not present.
CString Value = TempMap[LookupKey];

using find is the optimum solution to check existence, and using [] could never tell us whether we insert new pair or overwriting an old pair, all are correct understanding?

My question is how do I call show_available_music from Main.cpp.

I have a similar function that shows all the bands in a list.

cout<<"Whats the name of the band you want to search music from? ";
fflush(stdin); getline(cin,name);
band = myManager.select_band_name(name);
if(band!=0)
{
system("cls");
cout << "List of " << name <<"'s music.\n" << endl;
band->show_available_music();
}

void Band::show_available_music()
{
     list<Music>::iterator it;
     for ( it=available_music_list.begin() ; it != available_music_list.end(); it++ )
    cout << *it << endl;
