Assistance with unknown errors?

Having a few errors in my code (not stated by C++).
The program attempts to run a blackjack game.

One of the errors is that when an ace is drawn (I believe of any suit but spades), the ace is not displayed, but is still added to the score.

Another error is that if run continuously, the characters start to change and no longer work (the suit characters).

Also, when asked for another card or another game, if enter is pressed twice instead of y or n then enter, it skips that process and just says "you win!"

Sorry I don't have the comments done before each function. Pretty much, the main array has 53 parts, the 52 cards, then a last to tell the program that when it gets there....to re shuffle the array/deck.

Any help is very much appreciated, thanks.

The bug is probably directly related to your incorrect indentation (to understate things). It is never acceptable to put two closing braces on the same line under any halfway-decent coding style.

Make it all clean and tidy, like your conveniently named "clean" function and then we'll take a look at it. Everything inside a pair of curly braces should be indented furthur out. Search the web for how to indent code properly.
Replace tabs with a fixed number of spaces before posting.

So it seems the issue of the characters getting messed up and the 5 aces being drawn in a row comes when the deck runs out of cards. So obviously it is not shuffling at the end of the deck again?

Other than that, still same issues, sorry about initial indentation.
Once again, any advice is appreciated.

I hate doing this but: How To Ask Questions The Smart Way

really don't see what's wrong with the way I asked it. I was polite about it, I clearly identified what my problems are.

Any help would be incredible. Pleasee :(

That's a result of how scanf("%c", &answer) works. Hit enter twice, and the first call will give answer the character '\n', as will the second call.

If you look at the various checks your code does (in various places) of answer, you will see it just drops through to printing "You Win". You need to check more cases.

The reason you're not getting much help is that

1) You have posted a largish body of code
2) You have described your problems in a manner that assumes other people can easily understand the logic of your code.
3) The logic of your code is not that easy to understand: the names of variables are not informative, you have not included comments, and it is necessary for someone else to digest the whole mess to even make partial sense of it.
4) People here aren't paid for advice. If you only apply a small effort to solving your problem why should others put a larger effort in? Running a few test cases, as you have done, involves much less effort than reading your code and understanding it, in order to find the problems you describe.

If you want more informative advice, provide a small but complete example of code that illustrates each problem - and nothing else. In the process of creating those illustrative examples, you might solve the problem yourself (an "aha!" moment). If you can't, you will have code in a form that other people can give you useful advice on.

Sorry, I honestly didn't realize how much I was asking for until you blatantly stated it. Thanks for the tip on the You win case. Now that's fixed, I also fixed the ace not displaying issue by adding an if statement and another 13 cases in a separate switch statement. This is because 0 %13 is 13, but 13%13 is 0. But both these cases should be aces. This also required a quick change in the score function, to add an if statement there in the same way.

My only remaining problem now is that when the deck runs out, I don't think it reshuffles. I think this because the it draws 3 or 4 aces in a row, which would be the 0 % 13. But what's odd is that then it starts to draw cards like normal, but the characters get all messed up, now, I think this call should work for shuffle:

Code:

---

if (cardcount == deck[DECK_SIZE])
                            {
                                ShuffleDeck(deck);
                            }

---

This being the Shuffle Function:

Code:

---

void ShuffleDeck(int deck[DECK_SIZE])
    {
        int rand;
        int index;
        int dummy;
            for(index = 51; index >= 0; index--)
            {
              rand = RandomNumber(index);
              dummy = deck[rand];
              deck[rand] =  deck[index];
              deck[index] = dummy;
            }
    }

---

I still don't understand why the characters get messed up, it's very odd to me.

I think you want if (cardcount == DECK_SIZE).

GOT IT!
what i did is made it print the deck after the shuffle function.
It is shuffling it properly. The problem is that I didn't reset the cardcount afterwards.

Now the only issue I have left is small but odd, about half of the time I run the program, there is an issue that the score will increase by 10 but no card is displayed. But, it doesn't happen every time, even when I go through the whole deck. Any clue?
