We really only need to know that they are integers, the rest of the code 
explains how everything fits together. I want to make my TM interpreter 
as simple as possible.

The purpose of this thread is to simply confirm that the implementation 
of meets the specs:

THESE ARE THE SPECS:
For example, the quintuple 'SCcsm' is executed by the machine:

If it is in state 'S' and is reading the symbol 'C' on the tape then
(a) make a transition to state 's'.
(b) overwrite the symbol 'C' on the tape with the symbol 'c'.
      // Must do this before transition to state 's' or we lose 'c' from S.
(c) move the tape reading head one symbol to the left or right
      according to whether 'm' is 'l' or 'r'.

THIS IS THE IMPLEMENTATION:
struct Quintuple
{
   int state;
   int symbol;
   int write_symbol;
   int next_state;
   unsigned char Tape_Head_Move;
};

class Quintuple_List
{
   std::set<Quintuple> list;
   NextState(int next_state, int current_input)
   {
     Quintuple QT(next_state, current_input);
     return list.find(QT);
   };
}

bool transition_function(std::set<Quintuple>::iterator& current_quintuple)
{
   u32 next_state    = current_quintuple->next_state;
   u32 current_input = Tape[Tape_Head];
   std::set<Quintuple>::iterator next_quintuple;

   Tape[Tape_Head]   = current_quintuple->write_symbol;
   if (toupper(current_quintuple->tape_head_move) == ā€œLā€;
     Tape_Head--;  // Left
   else
     Tape_Head++;  // Right

   next_quintuple = NextState(next_state, current_input);
   if ( next_quintuple == Quintuple_List.end())
     return false;
   current_quintuple = next_quintuple;
   return true;
}
