Re: pass 2 D array in C

[Luciano Moreira - igLnx <lucianolnx@ig.com.br>]

The following sample was coded now, without compiling, then It can have 
some mistakes for compiler.
But I think that it ll can be good for your analyse. Using this sample, 
you can allocate any kind of array, like as 3D, 4D, 5D, and so on.

main()
{
   int THE_LENGTH = 200; /* Numbers of itens of array */
   long **p2DArray;

   pp2DArray = new long[THE_LENGTH];
   /* for C-ANSI: pp2DArray = malloc(sizeof(long) * THE_LENGTH); */

   fill_array(pp2dArray, THE_LENGTH);
   dump_array(pp2dArray, THE_LENGTH);

   delete pp2DArray;
  /* forC-ANSI:  free(pp2DArray); */
}

fill_array(char *pp, int nLength)
{
   int ct;
   for ct(=0; ct<nLength; ct++) {
      ppArray[ct] = (long) rand();
   }
}


dump_array(char *pp, int nLength)
{
   int ct;
   for (ct=0; ct<nLength; ct++) {
      printf("Item %d: %ld\n", ct, ppArray[ct]);
   }
}
