Question

Can someone help me get this C program to work? I am trying to get a 2d array to work correctly.

/* Deals a random hand of cards */
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define TRUE 1
#define FALSE 0
#define BOOL int
#define NUM_SUITS 4
#define NUM_RANKS 13
int main()
{
BOOL in_hand[NUM_SUITS][NUM_RANKS] = {FALSE};
int num_cards = 13, rank, suit;
const char rank_code[ 13 ][ 10 ] = {"Ace","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Jack","Queen","King"};
const char suit_code[ 4 ] [ 10 ] = { "Clubs", "Diamonds", "Hearts", "Spades" };
srand( time(NULL));
printf("Your hand :");
while(num_cards > 0) {
suit = rand() % NUM_SUITS;
rank = rand() % NUM_RANKS;
if (!in_hand[suit][rank]) {
in_hand[suit][rank] = TRUE;
num_cards--;
printf(" %c%c", rank_code[rank], suit_code[suit]);
}
}
return 0;
}

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define TRUE 1
#define FALSE 0
#define BOOL int
#define NUM_SUITS 4
#define NUM_RANKS 13
int main()
{
BOOL in_hand[NUM_SUITS][NUM_RANKS] = {FALSE};
int num_cards = 13, rank, suit;
const char rank_code[ 13 ][ 10 ] = {"Ace","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Jack","Queen","King"};
const char suit_code[ 4 ] [ 10 ] = { "Clubs", "Diamonds", "Hearts", "Spades" };
srand( time(NULL));
printf("Your hand :");
while(num_cards > 0) {
suit = rand() % NUM_SUITS;
rank = rand() % NUM_RANKS;
if (!in_hand[suit][rank]) {
in_hand[suit][rank] = TRUE;
num_cards--;

// %s should use not %c as it has strings to print
printf(" %s%s", rank_code[rank], suit_code[suit]);
}
}
return 0;
}
