Nested range based for loop over vector of pointers

I have an albumCollection, which is of type vector<Album*>. My Album class, in turn, holds a vector<Track*>. This works fine:

for(Album* i : albumCollection) {
    cout << i;
}

But trying this:

for(Album* i : albumCollection) {
    for (Track* j : i) {
        cout << j;
    }
}

I get the errors:

no callable 'begin' function found for type 'Album *'

and:

no callable 'end' function found for type 'Album *'

You need the vector that is contained in each Album to be on the right hand side of the : in the nested loop. That would look like

for(Album* album : albumCollection) {
    for (Track* track : album->name_of_vector) {
        cout << track;
    }
}
