Thread: help with pointers and arrays

Hey guys, I m having trouble trying to add values manually into the array and then getting them by iterating over it by calling these functions:

Code:

add(STRUCT night *a, char *val, unsigned *index);

and I get the values back by calling this function:

Code:

get(STRUCT night *a, unsigned index);

Here's my code:

Code:

#include <stdio.h>
#include "datarrays.h"


int main () {

struct night *a;

int pos1 =1;
int pos2 = 2;
int *ptr1;
int *ptr2;

ptr1 = &pos1;
ptr2 = &pos2;

add(a, "hello", ptr1);
add(a, "world", ptr2);


/* How do I print these values back..? */

printf ("%s\n", get(a, *ptr1);
printf ("%s\n", get(a, *ptr2);


return 0;
}

How do i get these values back by iterating over them instead? I get a segmentation fault. I dont want to manually get the values back (currently done).


Any help?

Thanks.

Ok... now show us ALL of your code... there isn't enough there to determine what the problem is.

That's why I've started calling them... seems as good a chance for a greeting as any!
