Mysql++ && printf

[timothy johnson]

I am having troubles getting my output to work with printf. 

gmod.cc:cannot pass objects of non-POD type `const class

This is part of the code I am playing with

Connection con(use_exceptions);
    con.connect("netjuke", "127.0.0.1", "******", "******");
    Query query = con.query();
    query << "SELECT location FROM netjuke_tracks Where al_id=17 AND
track_number=1";
    Result res = query.store();
    Row row;
    Result::iterator i;
    for(i=res.begin();i!=res.end();i++)
    {
        row = *i;
        printf("%s", row[0]);
    }

I change it from

    for(i=res.begin();i!=res.end();i++)
    {
        row = *i;
        cout << row[0];
    }

and this worked fine, but using printf doesnt
