passing an array from private class.

[wavy19]

hello there i have been stuck for 2 hours on trying to pass an array from private class to another:
here is my code:

class deck {
   private:
      card cards[52];
      int num_cards;
   public:
      void create_cards(card *cards,char *zat);
      void print();
      void shuffle(card *cards);
};

class game {
   private:
      deck cards;
      player *players;
      dealer game_dealer;
      int num_players;
   public:

      void n_players(int num_players);
      void create(card *cards);
      void shuffle(card *cards);
      void get_card2(card *cards);
      void print(card *cards);
};

int main(){
   card cards[52];
   char *z;
   char s;
   int n;

   game g;
   g.n_players(n);
   g.create(cards);
   g.shuffle(cards);
   g.print(cards);
   g.get_card2(cards);
}


void deck::shuffle(card *cards){
   for(int i=0; i<52; i++){
      int j=(rand()+time(0)) % 52;
      int temp = cards[i].value;
      cards[i].value=cards[j].value;
      cards[j].value= temp;
      char temp1 = cards[i].suit;
      cards[i].suit=cards[j].suit;
      cards[j].suit= temp1;

   }
}


void game::shuffle(card *cards){
   cards.shuffle(cards);
}

};

the error i get is:

t.cpp:199:10: error: request for member ‘shuffle’ in ‘cards’, which is of pointer type ‘card*’ (maybe you meant to use ‘->’ ?)
cards.shuffle(cards);

Since cards is a pointer you need to access it either with

cards->shuffle(cards);

or

cards[...].shuffle(cards);

But I don't think that you want either. Rather make shuffle(...) a free or static function.

Does cards have a function cards::shuffle(...) ?

I think you wanted to use deck::shuffle(...), or not?

Why don't you just make everything public: . Would this affect your code in another way?

I think someone needs a little refresher on the principles of OOP...
