Hi there,

I have a slight problem with implementing a dynamically allocated 2D array.
I was originally using 10 declerations of arrays in the following form:
char claimsTagArray[40][9]; but it seemed a slight waste of memory and time.

So i wanted to implement it dynamically so i only need to allocate memory to
it when i need it.

The following code is what i tried to use so far:

/****** CODE STARTS HERE ******/
char **createArray(int firstDim, int secondDim)
{
 char **newArray;
 int i;

 newArray = (char **)malloc(sizeof(char *) * firstDim);
 if(newArray == NULL)
 {
  printf("Unable to allocate memory\n");
  exit(0);
 }

 for(i = 0; i < firstDim; i ++)
 {
  newArray[i] = (char *)malloc(sizeof(char) * secondDim);
  if(newArray[i] == NULL)
  {
   printf("Unable to allocate memory\n");
   exit(0);
  }
 }
 return newArray;
}

void freeArray(char **array, int firstDim, int secondDim)
{
 int i, j;

 /*for(i = 0; i < secondDim; i ++)
  free(array[i][j]);
 */

 /*free(array);*/
}
/***** CODE ENDS HERE *****/

But it keeps crashing, if there are any ideas please contact me as soon as
possible.

Thank you in advance
Ren
