//  states_better.cpp (c) 1999-2004 Kari Laitinen

//  This program works in the same way as states.cpp
//  but this one includes the file <iostream> instead of
//  <iostream.h> and there is the appropriate using statement.
//  This program can probably be compiled with a wider range of
//  of C++ compilers as this is a more standard C++ program.

#include  <iostream>
#include  <string>    // class string etc.
