I have been having some problems with memory allocation using Borland's C++.
The problems seem to reside with the way sizes of objects are computed. An
example follows:

//************************************************

#include <stdio.h>

class c {
  public:
  char a[65536];
  }

void main() {
c b;

   printf ("Sizeof c: %ld\n", (long) (sizeof (c)));
   printf ("Sizeof b: %ld\n", (long) (sizeof (b)));
   printf ("Sizeof b.a: %ld\n", (long) (sizeof (b.a)));
   }

**********OUTPUT*************

Sizeof c: 2
Sizeof b: 2
Sizeof b.a: 65536


Doing a new() on an instance of class c results in only 2 bytes being
allocated. I have tried using both the compact and huge memory models.

I am new to both C and C++, so perhaps there is a simple misunderstanding
on my part. Anyone have any suggestions?
