C++ has an output maximum of 80 chars per line?

I'd like to output more than 80 characters per line into a txt-file. Is this possible?

Cheers,

Of course it's possible. If your compiler only allows 80 characters in a line (whatever a line is) then you can write multiple lines to the file without writing a newline character. Where are you getting that 80 character limit?

Perhaps the software you are using to view your files wraps at 80 lines, but there will be no line break unless you put one there.

Indeed, my browser wrapped it up, using another browser give no maximum at all.

Thnx for helping me out!

its always good to keep your output at 80 chars per line - it is not a rule set in stone, but most books and written documents have between 80-85 chars per line.

I have to agree here... the only time I would go over 80 characters is if it were some special application (ASCII image/graph etc.) and can print landscape, or if you're writing to a data file that never has to be/can be read by a human.

Ehh... Really, I'd say you guys are pulling a bit too hard for that rule. If it actually is meant for someone to read/look at through say a text editor or browser, then follow that rule. Otherwise, don't bother (it can be more of a pain to deal with). Anyway, this is just personal opinion.

*edit*
Actually, I take back what I said. I think it is much better to let the autowrap feature of whatever the user is attempting to view the file with handle that particular formatting. Not everyone's configuration will permit exactly the same length line, so you will get very puzzling and distracting line-breaks if you format it and an auto-wrap happens to be on.

well think about it this way: when somebody (probably a n00b) tells you they're having problems reading stats in from their data file, and they give you this as their file:

Code:

287:184,orage'1487"78?288:187,blue'1872"23?

A small sample such as the one you showed, I wouldn't mind. Granted, one should be careful to make things at least somewhat reasonable until s/he is skilled enough to be able to figure out what is going on with more cryptic data formats. I see no problem with what you posted, though.

i think CString has a limit somewhere around the 80 character limit...

CString, an MFC class for string handling, has a limit at roughly 2.000.000 characters. If you happen to need more, you are in a bit of trouble anyway, as the string would consume 2 GB of RAM.

Indeed. There is a difference though. If you use multiple strings to store your data, but you never include a newline character anywhere in them, then the effect of the smaller strings is completely transparent to the user.
