Defining a default constuctor outside the class.

Notamongsheep (28)
I'm having trouble defining a default constructor and destructor outside of the class. When i put TicketManager(); and ~TicketManager(); inside of the class as prototypes, it gives me a void _thisfunctioncall error. When I don't put them, it compiles fine but does not give any output when the object is created. here is my code, they are three seperate files.

 #ifndef TICKETMANAGER_H
#define TICKETMANAGER_H
using namespace std;

class TicketManager
{
	struct SeatStructures 				//Create a structure that contains the price of a seat and the seat's availability.
	{
		double price;
		char avail;
	};
	
	public:

	private:
	
	const static int rows = 0,			//Counter variables for the loops.
					 cols = 0;
	const static int S_ROWS = 15,       //Holds the values for the number of rows and columns.
					 S_COLS = 30;
	SeatStructures SeatChart[S_ROWS][S_COLS];
};

#endif

You get errors with this?

Yes, here's the compiler error.

project.obj : error LNK2019: unresolved external symbol "public _thiscall TicketManager::~TicketManager(void)" (!!1TicketManager@@AE@XZ) referenced in function _main

project.obj : error LNK2019: unresolved external symbol "public: _thiscall TicketManager::TicketManager(void)" (??0TicketManager@@QA@XZ) referenced in function _main

Are you sure all your object files are linking together in the same project?

This is a linker error. You must include both Project.obj and TicketManager.obj while linking the executable.

oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.. see... I was only trying to compile the main program. I guess I should've read that section on making seperate files. I'm so happy I could cry. Thanks guys... I'm so happy. Sad thing is, I probably would've never figured that one out.
