What about to make a "state" class containing something like this:

state states[NENSTATES];
// init the state instances with tables like this
SYMBOL LOAD 
 a      1
 b      23
 c      15
.... so on ..

you can start your machine just this way

states[0].take (symbol);

and 

void state::take (symbol s)
{
  next_state = lookup_in_my_table (s);
  if (!next_state) error ("this is not a language parsed by me");	
  next_state->take (symbol);
}
