  7. // Class: C Programming, Fall 2025

  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.   It
  17. // also calculates totals, averages, minimum, and maximum values.
  18. //
  19. // Array and Structure references are to be replaced with
  20. // pointer references to speed up the processing of this code.
  21. //
  22. // Call by Reference design (using pointers)
  23. //
