The problem is that when the project executes, it goes through an infinite loop after it is asked to register a new member. I am not able to correct that loop

[nuclearfroggy]

The infinite loop is occurring in the while loop at line 64, for me when the file fails to open. You need to make a test for the file facility.dat actually opening successfully. You also shouldn't test the while loop waiting for eof(), because you'll get a repeating character read at the end. Put the read as the conditional of the while loop.

If you want us to be able to help you please don't use Borland specific headers / functions, like the headers "graphics" and "conio". It makes it unportable so we can't compile it and start working through the code. Also, the Borland compiler is out of date so it would really be better to start using an IDE like Code::Blocks or Visual Studio (express) which are both free and up to date.

I want to help more but I'm in a bit of a rush and there is loads of code to sift through. I'd recommend splitting up the project into several files and header files, for example the class definitions and implementation could go into their own header / cpp files.

Now what can i do?? i have no idea.. you may mention the code to be written instead of the statement at line 64, so that my program runs.

Rather than asking for a magic bit of code to make it work, think about how to solve the problem.

You know you have a loop - now you have at least one indication of where the loop is. Can you test that hypothesis? Is it correct?

Under what circumstances does the loop become infinite? Can you detect that the loop is going infinite and manually break out of it?

DIC is a great resource, but please, you should be able to at least make some progress on this on your own.

i want the project to run ASAP! assist me in this

I'd love to drop my work to debug your 1000 lines of C, but I also have stuff that needs to be finished. If you really want to get help fast, you might try to refine your question. Can you at least verify that the problem is in one particular area of the code?
How would you go about that?

The issue in the code is that when the program runs, in the menu when we enter the choice no.1 i.e to register an new member, and after that we are asked to answer a question whether yes or no. after pressing yes the program goes to an infinite loop.
This is the major issue

[Skydiver]

I would imagine an infinite loop would be an issue. I'd be concerned, too.

What have you done to verify the problem is in one particular area of code? Have you stepped through it with a debugger? Have you tried putting in the file that it seems to want to have present? Have you simply tried disabling the code to see if that fixes the infinite loop? Have you tried implementing the fixes suggested in post #2?

Before post #2, it seemed like you yourself didn't know what was causing the infinite loop. We are not seeing any evidence in this thread of you trying to help yourself other than asking somebody else to fix the problem for you.

So in here, eh?

508	   {

510	      cout<<"\n DO YOU WANT TO SEE THE LIST OF FACILITIES AVAILABLE IN THE CLUB ? ";
511	      cout<<"\n YOU ARE ADVISED TO ENTER 'y' BEFORE FILLING THE FORM ";
512	      cout<<"\n ENTER y/n ---------> ";
513	      char ch;
514	      cin>>ch;
515	      if(ch=='y'||ch=='Y')
516	      {
517	     fac.show_facility();
518	     gotoxy(20,24);
519	     cout<<"PRESS ANY KEY TO CONTINUE";
520	     getch();
521	      }
522	      outfile.open("clubfile.dat",ios::app);
523	      member.get_data();
524	      outfile.write((char *)&member, sizeof(member));
525	      outfile.flush();
526	      outfile.close();
527	      add_fees_object(member.mem_code, member.date_of_joining, member.payment_code);
528	      cout<<"\n ANY MORE RECORD TO BE ENTERED <<y/n>> -------> ";
529	      cin>>choice;
530	      }
531	}

The question you refer to is the one at 512?
Now, help us narrow it down a little. When you see these lines:

 
510	      cout<<"\n DO YOU WANT TO SEE THE LIST OF FACILITIES AVAILABLE IN THE CLUB ? ";
511	      cout<<"\n YOU ARE ADVISED TO ENTER 'y' BEFORE FILLING THE FORM ";
512	      cout<<"\n ENTER y/n ---------> ";

and you hit 'y', what happens then? Do you enter the show_facility function? You can use a debugger or simply insert a print statement to find out. If you enter that function, how far do you get in it? Where is it that you get hung up?
If you get through that function, you'll get to the "PRESS ANY KEY TO CONTINUE" statement - does this happen?

You can find all of this out by either probing with prints or by using a step-through debugger. Please give it a try.

After pressing the "y" the code goes into an infinite loop. it doesn't enter the show_facility function. That is the major concern

Do you know this to be true? What have you done to test it?

I frankly see no way for it to fail to enter that method, so you'd better have a good answer for this. If you're not sure, test the bastard.

what should i do to test it. I am working on turbo compiler.

[jon.kiparsky]

Look for a necessary consequence of the code entering that function. Something obvious and unmistakeable. If there isn't one (there isn't) then make one. For example, put a print statement in it that executes if the function is entered. If you see that print statement, you got to there.
