       << "\n\nThe results of comparing s2 and s1:" 
       << "\ns2 == s1 yields " << ( s2 == s1 ? "true" : "false" ) 
       << "\ns2 != s1 yields " << ( s2 != s1 ? "true" : "false" ) 
       << "\ns2 >     s1 yields " << ( s2 > s1 ? "true" : "false" ) 
       << "\ns2 <     s1 yields " << ( s2 < s1 ? "true" : "false" ) 
       << "\ns2 >= s1 yields " << ( s2 >= s1 ? "true" : "false" ) 
       << "\ns2 <= s1 yields " << ( s2 <= s1 ? "true" : "false" );
