C++ problem?Black Jack

I am really use to C ,but not C++ so to ease myself into C++ I thought I would make a black jack game but OO is confusing me a little.It says my get_value() method is not a part of card_deck class or as G++ says

Quote

error: request for member ‘get_value’ in ‘deck’, which is of non-class type ‘card_deck ()()’
