How do I get emacs to open the file that a variable, function or class 
is defined in, given that it is in the current directory?

Example:

int main()
{
   Position pos;
   cout << pos << endl;

   Moves mvs;
   generateMoves(pos,mvs);
   for (int i = 0; i < mvs.size(); ++i)
     cout << mvs[i] << " ";
}

I want to be able to place the cursor anywhere in the "generateMoves" 
string, and press some keys, and then emacs should open, in a new 
buffer, the file where generateMoves is defined.

Have you looked at ffap.el, Exhuberant Ctags <url: http://sf.net/ > and 
perhaps speedbar.el? <url: http://cedet.sf.net/ >
Grep is also your friend.

For this you either need etags (ctags) - which is already shipped with Emacs
or the latest cedet-library (incl. semantic 2.0) which offers such
functionality too - current released beta is not perfect (AFAIK) but the
CVS-code of this library runs pretty well.
