Hi all. I was writing my program. And halfway through, i tried to compile and run. but got a blank output.

I tried doing a cout<<"hello"<<endl at the main() must still didn't get any display. could anyone please help me to see what went wrong?

You need to compile and fix errors a lot sooner than that!

>> void displayGame(list <Game>& myGame);

You have not coded that function.

oppss. realize i didn't quote the whole program. Anyway, before i wrote the displayGame(myGame) had tested the program and it works.
I have found where the error lies which is preventing the display from showing.

in the main function if i took out this :

if (!loadGameFile(myGame))
	{
    	exit(0);
     }//end if

and the display comes out. Any idea why?
