You are trying to call DeckOfCards  shuffle with a deckOfCards parameter   deckOfCards cardDeck     create DeckOfCards object cardDeck shuffle cardDeck      shuffle the cards in the deck   But the method takes a vector lt Card gt  amp    void deckOfCards  shuffle vector lt Card gt  amp  deck      The compiler error messages are quite clear on this   I ll paraphrase the compiler as it talks to you   Error    Error  no matching function for call to  deckOfCards  shuffle deckOfCards amp      Paraphrased      Hey  pal   You re trying to call a function called shuffle which   apparently takes a single parameter of type   reference-to-deckOfCards  but there is no such function    Error    Note  candidate is   In file included from main cpp   Note  void deckOfCards  shuffle std  vector amp     Paraphrased      I mean  maybe you meant this other function called shuffle  but that   one takes a reference-tovector lt something gt     Error    Note  no known conversion for argument 1 from  deckOfCards  to  std  vector amp        Which I d be happy to call if I knew how to convert from a   deckOfCards to a vector  but I don t   So I won t

to add to John s answer   what you want to pass to the shuffle function is a deck of cards from the class deckOfCards that you ve declared in main  however  the deck of cards or vector lt Card gt  deck that you ve declared in your class is private  so not accessible from outside the class  this means you d want a getter function  something like this   class deckOfCards       private          vector lt Card gt  deck       public          deckOfCards            static int count          static int next          void shuffle vector lt Card gt  amp  deck           Card dealCard            bool moreCards            vector lt Card gt  amp  getDeck         GETTER             return deck                 this will in turn allow you to call your shuffle function from main like this   deckOfCards cardDeck     create DeckOfCards object cardDeck shuffle cardDeck getDeck        shuffle the cards in the deck   however  you have more problems  specifically when calling cout  first  you re calling the dealCard function wrongly  as dealCard is a memeber function of a class  you should be calling it like this cardDeck dealCard    instead of this dealCard cardDeck     now  we come to your second problem - print to standard output  you re trying to print your deal card  which is an object of type Card by using the following instruction   cout  lt  lt  cardDeck dealCard      deal the cards in the deck   yet  the cout doesn t know how to print it  as it s not a standard type  this means you should overload your  lt  lt  operator to print whatever you want it to print when calling with a Card type
