Thread: Not able to access private data members

I'll continue to try my best to solve this complex problem.

This doesn't seem to work:

Code:

class BunchOfCards
{
  public:
    Card DealACard();
    friend ifstream& operator >>(ifstream& ifs, BunchOfCards& bcds);
    friend ostream& operator <<(ostream& ofs, BunchOfCards bcds);
  private:
    vector <Card> mSomeCards;
};

Card BunchOfCards::DealACard()
{
  Card b, targetPosition;
  targetPosition=mSomeCards.size();
  for(int i=targetPosition;i<mSomeCards.size();i++)
  {
    mSomeCards[i]=mSomeCards[i+1];
  }
  mSomeCards.pop_back();
  return b;
}

Now, I'm trying to do something here, and I know that I am not doing it right. I've got to start somewhere, so I have. I have been instructed to:

Consider that the last card pushed back onto the vector is the "top" of the BunchOfCards. Write a member function that takes the top card off of BunchOfCards.
...Returns the top card and takes the card out of the bunch of cards.

I am a bit lost here as well. Thanks
