  18. // Function: validateIrishLicense
  19. // 
  20. // Purpose: Receives information on the year, half year, 
  21. //          county, and a one to six-digit sequence number which 
  22. //          are used to validate an Irish license plate and return 
  23. //          a True value (1) if the license plate is valid, 
  24. //          otherwise a False value (0)
  25. // 
  26. // Parameters:
  27. // 
  28. //     year -  Two digit year (2013 would be 13, 2014 would be 14, and so on .. through 24 for 2024. Any other year is invalid)
  29. //     halfYear - Number used to represent the half year. A 1 indicates the car was sold between Jan-Jun, while a 2 between July-Dec
  30. //     county - A character value that represents the Irish County where the car was registered
  31. //     sequence1 - A one to six-digit sequence number, starting with the first vehicle registered in the county/city that year/period
  32. //      
  33. //
  34. // Returns: a True value (1) if the license plate is valid, otherwise a False value (0)
