unfortunately, it's not exactly clear to me what you want to measure.
The "memory consumed by a class" might be as easy as the "sizeof"
operator in C++:

#include <cassert>
struct foo { double d; };
int main()
{
  assert( sizeof( foo ) == sizeof( double ) );
}

But this of course only covers the "static size" of your classes.  If
they allocate additional memory during runtime, this can not be
determined by sizeof.

If you want to look at the overall memory/heap consumption of your
program over the time, you can have a look at the Valgrind tool suite.
IIRC, they have a heap profiler.

Greetings from Oldenburg,
