>> i have forgotten how to do the setw for the output
You also forgot to use Code Tags. Thus I forgot to help, sorry.

/* LOL that's funny. i meant that i want to line the numbers up for the section below after u compile & run it.:

cout << "Find Allen, Jim: ";
      cout << binarySearch ( "Allen, Jim", names, 20 ) << endl;
      cout << "Find Wolfe, Bill: ";
      cout << binarySearch ( "Wolfe, Bill", names, 20 ) << endl;
      cout << "Find Jones, Kevin : ";
      cout << binarySearch ( "Jones, Kevin", names, 20 ) << endl;
      cout << "Find Holland, Beth: ";
      cout << binarySearch ( "Holland, Beth", names, 20 ) << endl;
      cout << "Find Vasko, Paula: ";
      cout << binarySearch ( "Ross, Paula", names, 20 ) << endl;

cout << setw( 20) << "Find Allen, Jim: "; use whatever number of spaces will contain your longest string.
Remember that setw is not a sticky setting.
