  11. // Description: Program which determines overtime and 
  12. // gross pay for a set of employees with outputs sent 
  13. // to standard output (the screen).
  14. //
  15. // This assignment also adds the employee name, their tax state,
  16. // and calculates the state tax, federal tax, and net pay.   
  17. // It also calculates totals, averages, minimum, and maximum values.
  18. //
  19. // Array and Structure references are replaced with
  20. // pointer references to speed up processing.
