hi,

i was wondering if anyone could help me out with this. i'm getting a compile error like this:

[C++ Error] TestDriver.cpp(26): E2285 Could not find a match for 'Airport::Airport(char *,double,char *,FlightsTL)'

i'm really sorry about this but the code is a bit lengthy. it comprises of two header files and three CPP files (two files that correspond to the header files and one TestDriver). I have to post all of the code so that you can get an understanding of what's happening. basically i'm trying to make the airport have a flight schedule by using the FlightsTL classes objects

Anyone got anything?

I don't see a constructor for this call.

Airport a("syd",0.30,"Sydney domestic airport",C);

So do you have the above constructor implemented in your code? I didn't see it. If you do not, you cannot make the above call. The closest I see is this:

Airport::Airport(const std::string &,const double &,const std::string &,const Flight &)

C is type FlightsTL, not Flight&

Also, you can post your code using C++ style code tags:

[code=cplusplus] // paste code here

[/code]

This will add line numbers to your code so you can refer to them in the writeup, and say which line the error is coming from. That'll help a lot with code this big.

Thanks for having a look, i will give that a try! and i will use the c++ tags from now on, sorry about that(didn't know):$

Anyone got anything?

There is one 'oddity' that needs to be pointed out, namely usage of '\\' as end-of-comment marker. The backslash at the end of the single line comment works as a line continuation character and hence the next line is also taken as comment. You have one instance of this happening, i.e.

//------------end of house-keeping------------------\\
		   int AirportsTL::getAirportsNum (){ <- this line turns into a comment

So it's better to use something else to end the comment lines.

You have some type mismatches there + something else too

setScheduel(FlightsTL plan); 
// maybe you meant just (?)
setScheduel(plan); 

// ----------------------------------
// Fplan is not of type FlightsTL
setScheduel(Fplan);

// ----------------------------------
// you don't have a ctor taking only 3 arguments
Airports.push_back(Airport(code,minCon,desc));

// ----------------------------------
// C is not of type Flight
Airport a("syd",0.30,"Sydney domestic airport",C);

you are right in what you said, it compiles now

and it does take the object ie C, but any idea how i would check to see that the C is actually there?

i thought of using airport classes tostring() to do it but have no clue where to start

string Airport:: toString()const{

			   string s;
				  double mCon = getMinimumConnectionTime();

				   // convert double to string
				  char mConStr[50];
				  sprintf(mConStr,"%g",mCon);

				  // print all Airport information
				  s=getCode() +"\t"+ mConStr + "\t"+ getDescription() + "\n" ;
					return s;

		   }

thanks again for answering previous question

I don't understand what you are asking here in red. You were close on the code tags, but you had a space in there and you forgot an s:


[code =cpluplus]

You don't want the space. You want it like this:

[code=cplusplus]

I was refering to the C object i created in the TestDriver

FlightsTL C;
		 //Attempt to put Flight object into FlightsTL
		 //there is an error when this line is uncommented
	C.addNewFlight("syd","per",1.00,1.30);
	C.addFlight(b);
	   //Constructor for airport trying to make it accept a set of flights at the end

	Airport a("syd",0.30,"Sydney domestic airport",C);

I need to know how to print out each Flight's detail (from C), i am thinking of writing a Fuction like this

/*
		   * print all Flights
		   */
		   string Airport:: PrintFlights(){


					 getScheduel();




		   }

then calling that PrintFlights() in my toString for Airport class. But dont know how to implement the PrintFlights function.

Well, Airport has a data member called "scheduel", which is of type FlightsTL. FlightsTL has a data member which is a vector of type Flight called Flights. Do you have an Airport:: PrintFlight() function? If so, I would traverse the Flights vector and make a call to that function for each Flight in the Flights vector:

string Airport:: PrintFlights()
{
    for (int i = 0; i < scheduel.Flights.size(); i++)
    {
        Flight aFlight = scheduel.Flights.at(i);
        aFlight.PrintFlight();
    }
}
