Thread: Sorting and help with arrays

I have a program due that is to take 5 random cards from a deck, declare what suit they are and give the number of the card. Ul;timately what i need to do after this is to have them filter the cards into like numerical order.... basically put them lowest to highest ( from top to bottom) I got the code for this worked out but I am unsure how to get it to display H,C,S, or D for the suits. I got it to do a random number 0-4 for that display but I cant get it to display H C S or D. Also I am unable to get it to sort the array. I am unsure of the code and I know its really simple for all you people who do it all the time but its a basic beginner course and im having a bit of a hard time. Ill paste the code below. Any help is greatly appreciated

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
    int iValue, iSuit;
    int iLoop, iLoop2;

    float position[3];

    bool bCards[4][13];

    // Initializing the array
    // aka, putting all of the cards in the deck
    for(iLoop = 0; iLoop < 4; iLoop++)
        for(iLoop2 = 0; iLoop2 < 13; iLoop2++)
            bCards[iLoop][iLoop2] = 1;

    // Seeding the random number generator
    srand(time(NULL));

    printf("\n\n");
    printf("Suit      Value");
    printf("\n");
    printf("----      -----");
    printf("\n");

    for(iLoop = 0; iLoop < 5; iLoop++)
     {
        iSuit = rand()%4;
        iValue = rand()%13;

        while(bCards[iSuit][iValue] == 0)
        {
            iSuit = rand()%4;
            iValue = rand()%13;
        }

        printf("  %2d       %2d", iSuit, iValue);
        printf("\n");

        // Removing the card from the deck
        bCards[iSuit][iValue] = 0;
      }
      system("PAUSE");
      return 0;
}

ok I think i figured it ould actually got something acomplished but i may need one thing done.....

Code:

 

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
  int i,j,k;
  bool cards[52];
  char *suits[]={"Heart   ",
                 "Club    ",
                 "Diamond ",
                 "Spade   "};
  char *faces[]={"Ace  ","1    ","2    ","3    ","4    ","5    ","6    ",
                 "7    ","8    ","9    ","10   ","Jack ","Queen","King "};

  // Initializing the array
  // aka, putting all of the cards in the deck
  for(i = 0; i < 52; i++) {
    cards[i] = 1;
  }

  // Seeding the random number generator
  srand(time(NULL));

  printf("Before Sorting\n\n"
         "  Suit      Value\n"
         "  -----     -----\n");
  for(i = 0; i < 5; i++) {
    do {
      j = rand()%52;
    } while(cards[j]==0);
    // Removing the card from the deck
    cards[j] = 0;

    printf("  %s  %s\n",suits[j/13],faces[j%13]);
  }

  // sort the cards
  printf("\nAfter Sorting\n\n"
         "  Suit      Value\n"
         "  -----     -----\n");
  for(i=0;i<13;++i) {
      for(j=0;j<4;++j) {
          k=i+j*13;
      if(cards[k]) {
  printf(" %s %s\n",suits[k/13],faces[k%13]);
                   }
                       }
                     }

  system("pause");
  return 0;
}

I just want it to sort the cards it already picked. The way it works, is that I think it prints out 47 cards and not the ones that were already picked. Do you know how I can fix this? Maybe there is just a little trick I need to do in the code to make it work?

Code:

    if(cards[k] == 0) {
