15.7.10.Case-Sensitive Substring Comparison: generalization of strncmp()

#include <iostream>

#include <string>



using namespace std;

   string saying2( "this is another test" );



   // generalization of strncmp()

   cout << "\n\nCOMPARE SUBSTRINGS OF DIFFERENT LENGTHS AND INDEXES\n";

   if( saying1.substr( 2, 11 ) < saying2.substr( 14, 17 ) )

      cout << "\"" << saying1.substr( 2, 11 ) << "\" is less than \""

         << saying2.substr( 14, 17 ) << "\"";

   else if( saying1.substr( 2, 11 ) > saying2.substr( 14, 17 ) )

      cout << "\"" << saying1.substr( 2, 11 )
