[Dev-C++] Question about pointers vs 2-D arrays

[<and...@su...>]

Dear users,

   Can anyone tell me what formula I
can use to referenciate one 2-D array
element dynamically allocated?

Example:
...
#include <stdlib.h>
...
int main()
{
   double *2d_array; /* I want to use a 3-row 2-column 2-D array */

   2d_array = (double *) malloc(3*2*sizeof(double));
   /*
      2d_array[0][0] 2d_array[0][1]
      2d_array[1][0] 2d_array[1][1]
      2d_array[2][0] 2d_array[2][1]

      becomes:
      *(2d_array+0), *(2d_array+1), *(2d_array+2), *(2d_array+3),
      *(2d_array+4), *(2d_array+5)
   */
   ...
   /*
      I need to find a way to do assignments like this:
      2d_array[2][1] = 4.0;
      but I need to do it by a GENERIC (for every MxN 2-D array,
      not just for a 3x2) linear combination of
      the indexes, something like *(2d_array + 5) = 4.0;
   */

}

   Any ideas?

Regards
Andre
