empty character constant problem

Moderator note: this thread inappropriately resurrected empty character constant ??

Hey guys. sorry about jumping in on somebody elses thread, but my problem is the same.

I had an empty character constant problem, but I really dont know what the fill the ' ' empty space with.
Ive taken a screen shot of a portion of the code, if it would help you to help me I can of course upload the code so you can see it all.

I don't see an empty character constant in the code (do you have a line number to go with it).

I think I have displeased the gods in resurecting this thread. Should I start a new one for my problem?

Oh sorry...
I added a 'j' character as I was working to see if it would change.
Adding the j produces an error when I run the app, but when I comment out the ' ' code line the same error is produced.

Would it be better if a posted the whole code so you would better able to help me.

Probably. Please post it well indented in [code][/code] bbcode tags, and do not start a new thread for this.

So you have to figure out what you want to print. If you want to print a blank space, then that's what you should print:

Code:

---

' '

---

as opposed to

Code:

---

''

---

The crash is unrelated to this and is based on you doing something wrong somewhere else.

Ok, I just changed it from '' to ' ' and your right the error is the same.
The code is 128 lines long, I cant see if there is a limit on here as to how long the code can be, so I hope its not against the rules.

Code:

#include <cstdlib>

#include <windows.h>

Thats my code, as you can see its nothing special, im only in my first year.
The error is it continiously produces a colured line in an endless loop... line after line after line.
Can you see what Ive done wrong, my eyes are going square looking ((

I intend to make the class into a haeder and then run it from main by sinply including the header and then the data capture as you can see, thats why main is at the bottom... can I do it like that?

You read in ht, and then proceed to set_wth(wd), where wd has garbage value.

I see. I got it now, thank you ))
O.U.1
