using std::string;

int main()
{
   string string1( "AAAAAAAAAAAAAA" );
   string string2( "BBBBBBBBBBBBBB" );

   string string4( string2 );
   
   cout << "string1: " << string1 << "\nstring2: " << string2
      << "\nstring3: " << string3 << "\nstring4: " << string4 << "\n\n";

   // comparing string1 and string4
   if ( string1 == string4 )
      cout << "string1 == string4\n";
   else{ 
      if ( string1 > string4 )
         cout << "string1 > string4\n";
      else // string1 < string4
         cout << "string1 < string4\n";
   }

   return 0;
}

string1: AAAAAAAAAAAAAA
string2: BBBBBBBBBBBBBB
string3: CCCCCCCCCCCCCC
string4: BBBBBBBBBBBBBB

string1 < string4
