    Card Displayer

    I wrote this code that displays a card that could be used in a card game in the future.

    I got the stuff on making colors here:

    Wonderful Tutorial

    Code:
    #include <iostream.h>
    #include <cstdlib>
    #include <windows.h>
    #include <string>
    #include <ctime>
    
    #define FW  FOREGROUND_RED |\
                FOREGROUND_GREEN |\
                FOREGROUND_BLUE
    #define BW  BACKGROUND_RED |\
                BACKGROUND_GREEN |\
                BACKGROUND_BLUE |\
                BACKGROUND_INTENSITY
    #define FR  FOREGROUND_RED | \
                FOREGROUND_INTENSITY
    #define BB 0
    
    using namespace std;
    
    void Black (string cardtype);
    
    void DrawCard (string cardtype, string cardnum);
    
    string CardType ();
    
    string CardNum ();
    
    int main()
    {
    string cardtype;
    string cardnum;
    cardtype = CardType();
    cout<<"\n\n\n";
    cardnum = CardNum();
    DrawCard(cardtype, cardnum);
    cin.get();
    
    return 0;
    }
    
    void Black (string cardtype)
    {
          HANDLE hOut;
    
          hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    
          SetConsoleTextAttribute(hOut,
                                FW | BB);
    
          cout << "           ";
    
          if (cardtype == "S" || cardtype == "C") {

                           FR | BW);
          }

    What do you think?

    It won't compile on VC++ 2003 --> <iostream.h>

    It's very basic, I've made a few changes:
    Should show card symbols instead of H,D,C,S
    Should use 10 instead of T
    srand should only be called once. Move to main()
    Now to make this usable, you need a way to draw more than one card on a line, I'll leave that for you to do.
    Also, after every draw you should return the colors back to the default so that any text output is "normal".

    Code:
    #include <iostream>
    #include <cstdlib>
    #include <windows.h>
    #include <string>
    #include <ctime>
    
    #define FW  FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE
    #define BW  BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE |BACKGROUND_INTENSITY
    #define FR  FOREGROUND_RED | FOREGROUND_INTENSITY
    #define BB  0
    
    using namespace std;
    
    void Black (string cardtype);
    
    void DrawCard (string cardtype, string cardnum);
    
    string CardType ();
    
    string CardNum ();
    
    int main()
    {
        srand(time(NULL));  // This should only be called once so moved to main()
    
        string cardtype;
        string cardnum;
        cardtype = CardType();
        cout<<"\n\n\n";
        cardnum = CardNum();
        DrawCard(cardtype, "10");
        cin.get();
    
        return 0;
    }
    
    void Black (string cardtype)
    {
        HANDLE hOut;
        hOut = GetStdHandle(STD_OUTPUT_HANDLE);
        SetConsoleTextAttribute(hOut, FW | BB);
    
        cout << "           ";
    
        if (cardtype[0]>4) 
        {
            SetConsoleTextAttribute(hOut, BB);
            SetConsoleTextAttribute(hOut, BW);
        }
    
        else 
        {
            SetConsoleTextAttribute(hOut,FR | BW);
        }
    }
    
    void DrawCard(string cardtype, string cardnum)
    {
        Black(cardtype);
        cout << "       " << endl;
        Black(cardtype);
        cout << "       " << endl;
        Black(cardtype);
        // handle the 2 digit 10
        if(cardnum == "10" ) cout << "  " << cardnum << "   " << endl;
        else cout << "   " << cardnum << "   " << endl;
        Black(cardtype);
        cout << "       " << endl;
        Black(cardtype);
        cout << "   " << cardtype << "   " << endl;
        Black(cardtype);
        cout << "       " << endl;
        Black(cardtype);

    I only use T because otherwise the width of the card would be too big as 10 is two characters.

    Of course it is basic...I'm a fauking NOOB!

    Yes, i know why you used the T, as my code shows, you need to adjust for the 10

    You said you wanted to be able to use it in a future game, by me saying it's basic, that's my nice way of saying it's crap, it's not ready to be used in a card game. I gave a few suggestions to help get it to that point.

    Did you look at the code I posted? I made all the changes I suggested except the one I said you would have to do: Ability to draw more than one card on a line

    Yes, it's not portable but since you're using window specific code anyway it doesn't matter
