using std::string;

int main()
   string s1( "AA1234567890asdfasdf" );
   string s2( " AAB" );
   string s3;

   // test string member function substr
   cout << "The substring of s1 starting at location 0 for\n"
      << "14 characters, s1.substr(0, 14), is:\n"
      << s1.substr( 0, 14 ) << "\n\n";

   return 0;
The substring of s1 starting at location 0 for
14 characters, s1.substr(0, 14), is:
