With one change , the code is working fine


string MainMenu::choose_from_main_menu (string choice)
{
cin>>choice;
return choice;
}

Am I missing something ???
fofa (20)
Ok guys.. I added the return choice..
But I got a very weird error:
1>------ Build started: Project: cs102 proj, Configuration: Debug Win32 ------

Hmm. That sounds like an error relating to your main and #includes.
fofa (20)
Btw i didn't write the main yet. I'm compiling on separated files. Is that ok?

And about the error.. What should I do?
tummychow (1210)
I'm not sure. I'm not really too good with linker errors.
What other files do you have? Put those up on pastebin. (that is, files besides the main menu)

I think its probably that you haven't got main() yet. Every program must have a main that returns something. Why not try quickly creating a main()?
fofa (20)
Yep ! You were right.. I needed a main.
It is working now. Thanks..
fofa (20)
I need a help with the main loop now though!
fofa (20)
This is the loop.. It's not done yet.
But here when according to this code, the loop is supposed to stop when you enter 0.
Here the 0 is considered with the "else" and says invalid ! Why?

else if(!number)

this code is very long, do you people think it's better if the messages is save on a textfile then retrieve it when need to shorten the code?

My dear.. I'm not very good with files..
I think I'd ruin the program if I used files more than it's already ruined!
I'm out of time n' need to finish it by today! :( I don't really think its a good idea for me to add files here.

Yeah that worked! Thanks..


Can someone check what's up with the 102 errors all of a sudden !!?????
luckycusp (105)
which 102 errors?
fofa (20)
Ah.. I changed lots of stuff..
Can someone check these links and tell me what I should do?? ! I'm literally depressed now because of it. Whenever I do something it is wrong.

I still didn't wrote the security menu..
But for now this is it.

The main loop IS my major problem i don't know how to do it.


Interface for MainMenu:
http://paste.uni.cc/20464 <<< the private part is empty. I don't know what to put!!!
Implementation for the MainMenu:
http://paste.uni.cc/20465

Interface for Passenger menu:
http://paste.uni.cc/20466
implementation for passenger menu:
http://paste.uni.cc/20467

This is the main()
http://paste.uni.cc/20468 << Not complete and the loop is wrong but it's just the beinning.

Note that there's the security menu.. I'd do it the last thing.
mcleano (922)
I haven't checked your links but unless a program is quite large in size, 102 erroros probably means you're doing the same thing over and over again, one error is causing the convsecutive errors.

Can you name some of the errors along with the file it is associated with?
