I'm having some issues with inheritance. I have included the two different classes that I'm working with (WorkTicket & ExtendedWorkTicket). ExtendedWorkTicket should be using the member variables of WorkTicket, which is why I have used them as protected.
My issue comes in when I try to create the default constructor for ExtendedWorkTicket. I get an error telling me that ExtendedWorkTicket doesn't have the field names [...] (all except myIsOpen).
I know I can replace all those member variables with WorkTicket(1, "", 1, 1, 2014, "") in the constructor, but that changes the functionality as it would be calling the Parameterized constructor from WorkTicket and tries to validate them using the setters, which it shouldn't be doing.
I need it to just create a blank WorkTicket (with the extra myIsOpen member), like what the WorkTicket's default constructor does.
class WorkTicket
{
public:
/***************************************************************************
* Default and parameterized constructor(s).
* If parameters are not specified, set the work ticket number to zero,
* the work ticket date to 1/1/2000, and all other attributes to empty

WorkTicket() : myTicketNumber(0), myClientId(""), myDate(1, 1, 2014), myDescription ("") { }
WorkTicket(int ticketNumber, string clientId, int day, int month, int year, string description);
/***************************************************************************

WorkTicket(const WorkTicket& original);

And the inheriting child class:

Remove the initializations of the base-class members; those are handled by the base-class constructor. You don't need to explicitly call out the base constructor, but you can if you think that's clearer.
