*Im sure most of them are easy, I just cannot figure them out, Thanks for the help! 

[Moschops]

virtual ~Deck():
Should that be a semi-colon?

 m_Deck.Deal(m_House);
)

Should that final ) be a } ?

m_house.FlipFirstCard();
Case matters.

There is more. Fix the above, see if the new errors are helpful to you.

[NathanOliver]

Line 270: virtual ~Deck():

Notice anything wrong with that?

[Moschops]

Two people independently told you about the colon at the end of that line, and your reply (in a comment on Nathan's response, no less) is that because the compiler didn't put a big neon sign on it, it must be correct?

I am genuinely astounded that you didn't even try what two people independently told you. Do any of your other function declarations finish with a colon instead of a semi-colon? Do you do that a lot?

[Maritimo]

My recomendations are:
You must write the << operators
I don't think is a good idea to Derive Deck from Hand
I recomend you to use the following hierarqui:

  Card n.........1 GroupOfCards
                    |        |
                    |        |
                  Hand      Deck
                    |
                    |
              GenericPlayer (v)
               |         |
               |         |
         (v) Player    House (v)


  Deck 1.....1 Game 1....1 House
                 1
                 .
                 .
                 n
              Players

Make the program more compact, this will help you to understand.
Don't write anything that is not strictly necessary.
Don't use pointers (new, delete).
Use the C++11 new facilities like for(auto& card : m_Card) //...

[Lilgenski16]

I did, try what the two others said, and it did end up working, sorry about saying that "it didnt work"

[Maritimo]

Lilgenski16: As you solved the problem and I think this could be a good example to show another style of programming, I am appending my own version (based on yours).

I think that writting a program is like writting a book, that is, there aren't a fixed number of rules that you must follow. The idea when writting a program is to express what you want in the best way for other humans comprehension.

Based on that, I like to write using the minnimum number of line codes and don´t writting things that are completly unnecesary. In this program, for example, the destructors don't need to be virtual; as a matter of fact, you don't need any destructor at all. So I deleted all the destructors. The default destructors are enough.

I would like to read others comments about the programmings style.

So, my complete alternative, written in C++11 full commented with 295 lines of code is the following:

Any comments?

[マーズ maazu]

i was thinking of Unicode characters for representing card suits and other text line graphics. If you want a better representation of Blackjack, i recommend SFML.

[Maritimo]

Maazu: Sure, thanks. I must admit that I don't know how to use other characters than ASCI in a system independent mode. If you can write a post with this in mind I'll appreciate.

[マーズ maazu]

You know Windows -> Accessories -> Char map utility? have Arial font mappings for the following extended ASCII: U+2660 ♠ , U+2665 ♥, U+2663 ♣, U+2666 ♦

test if your DOS prompt can render it with a simple 1 liner:
std::cout << std::string("\u2663") << std::endl;

Otherwise you might need PDCurses (mingw) or ncurses (Unix) library linked and execute it with MSYS 1.0, TERM = VT100 emulation. It will be alot easier if you are running Linux+GNOME Terminal or KTerm.

Following your recomendations, the operator<< of class Card must be changed to:

ostream& operator<<(ostream& os, const Card& card)
{
  switch(card.m_Rank)           
  {
    case Card::ACE:   os << "A"; break;  //        Program Hierarchy       |
    case Card::TWO:   os << "2"; break;  //                                |
    case Card::THREE: os << "3"; break;  //             GroupOfCards       |
    case Card::FOUR:  os << "4"; break;  //               /     \          | 
    case Card::FIVE:  os << "5"; break;  //              /       \         | 
    case Card::SIX:   os << "6"; break;  //             /         \        | 
    case Card::SEVEN: os << "7"; break;  //    (v)GenericPlayer   Deck     | 
    case Card::EIGHT: os << "8"; break;  //         /       \              | 
    case Card::NINE:  os << "9"; break;  //        /         \             | 
    case Card::TEN:   os << "10";break;  //       /           \            | 
    case Card::JACK:  os << "J"; break;  // (v)Player        House(v)      | 
    case Card::QUEEN: os << "Q"; break;  //                                | 
    case Card::KING:  os << "K"; break;  // (v):virtual                    | 
  }                     

  switch(card.m_Suit)               
  {
    case Card::CLUBS:    os << "\u2663"; break;
    case Card::DIAMONDS: os << "\u2666"; break;
    case Card::HEARTS:   os << "\u2665"; break;
    case Card::SPADES:   os << "\u2660"; break;
  }

  return os;
}

With this, some play can look like:

-------------------------------------------------- Lets go:
Player a: 10♣ 4♥  (2 cards)
Player b: 5♣ 5♥  (2 cards)
Player c: J♥ Q♠  (2 cards)
House:  (2 cards)

Player a, do you want a hit? (Y/N): y
Player a: 10♣ 4♥ 3♥  (3 cards)
Player a, do you want a hit? (Y/N): n

Player b, do you want a hit? (Y/N): y
Player b: 5♣ 5♥ K♣  (3 cards)
Player b, do you want a hit? (Y/N): n

Player c, do you want a hit? (Y/N): n

House: K♦ 9♥  (2 cards)

House:  (19)
Player a:  (17) loses.
Player b:  (20) wins.
Player c:  (20) wins.

Do you want to play again? (Y/N): n

Nice, isn't it?

[マーズ maazu]

Yes, output looks encouraging! Now, i recommend refactoring your classes, namely "Player" class into client/server model.
How far do you plan to go with this project?

[Maritimo]

Well, this project really is from Lilgenski16. I did it completelly because I wanted to use it as an example as a programming style in the forum to be commented by everybody. My idea was to show that the original program did by Lilgenski16 is to long and dificult to undertand (in my opinion) and my solution, based on exacly the same idea, is very more compact and, I think, more easy to be undertand. Obviously all of this this is subject to debate.

[Maritimo]

Maazu: Following with this programming style open example, should be very interesting and instructive if you can show the modifications to implement your idea of client/server model. Hope you have the time to do that.

[マーズ maazu]

I'm sorry i cannot do that. Operating system, be it linux or windows, uses different socket types... I am sorry, i cannot do it.
