Strings and Arrays... Could someone please help?

Hi,

I have an input file whos data needs to be entered into a one-dimentional array. The data file is as arranged as shown below.

Each line is to be entered into a single array entry as a string.

The code I have used so far (which doesn't work) to do this is shown below also.

Thanks for any help

Rob
Code:
DATA FILE
---------
1 S 1
2 S 2
3 S 3
4 S 4
5 S 5
6 S 6
7 S 7
8 S 8
9 S 9
10 S 10
11 S 11
12 S 12
13 S 13
1 H 14
2 H 15
3 H 16
4 H 17
5 H 18
6 H 19
7 H 20
8 H 21
9 H 22
.
.
.
10 C 49
11 C 50
12 C 51
13 C 52


Code:
C FILE
------
#include <stdio.h>

main()
{
char cardData [7] ;
char fullArray [52] ;
int counter ;

FILE *card_data_file = fopen ("cards.dat", "r") ;

for (counter = 0 ; counter < 52 ; ++ counter)
   {
   fgets (cardData, 7, card_data_file) ;
   strcpy (fullArray [counter], cardData) ;
   }

}

Here is a simple way that you could do it:
Code:
#include <stdio.h>
#include <string.h>

typedef struct _card {
        int id;
        char suit;
        int placement;
} card;

main () {
        card deck[52];
        int counter=0;
        char working[10];
        char *temp=&working[0];
        char *test;
        FILE *card_data_file;

        bzero(working,10);

        card_data_file = fopen("data.txt","r");
        if (card_data_file == NULL) {
                printf("Error reading card data file.");
                return -1;
        }

        for(counter=0;counter < 52;counter++) {
                fgets(temp, 10, card_data_file);
                deck[counter].id=atoi(strtok(temp," "));
                test=strtok(NULL," ");
                deck[counter].suit=test[0];
                deck[counter].placement=atoi(strtok(NULL," "));
        }
        fclose(card_data_file);

        for(counter=0;counter < 52; counter++) {
                printf(" Card %d%c is at position %d in the deck\n",
                                deck[counter].id,
                                deck[counter].suit,
                                deck[counter].placement);
        }
        printf("\nEnd\n");
        return 1;
}
