Cout << "\n"; is dumb and you should feel bad
No debate, std::endl can be a disaster on some platforms due to flushing crap all the time.
I am very sorry to remind everyone about the existence of Visual Basic, but it has:
- VbCrLf
- VbNewLine
- ControlChars.CrLf
- ControlChars.NewLine
- Environment.NewLine
- Chr(13) & Chr(10)
And I know what you're asking: Yes, of course all of them have subtly different behavior, and some of them only work in VB.NET and not in classic VB or VBA.
The only thing you can rely on is that "\r\n" doesn't work.
Apology not accepted, fuck you for reminding me!
great reminder to avoid microsoft products as much as i can
print('string\n', end='')
I just learned that in Python, it's fucking terrible. Python is a fucking mess and my next script will be in a different language.
If endl is a function call and/or macro that magically knows the right line ending for whatever ultimately stores or reads the output stream, then, ugly though it is, endl is the right thing to use.
If a language or compiler automatically "do(es) the right thing" with \n as well, then check your local style guide. Is this your code? Do what you will. Is this for your company? Better to check what's acceptable.
If you want to guarantee a Unix line ending use \012 instead. Or \cJ if your language is sufficiently warped.
Ah don't worry, if you do fopen(file, "w") on Windows and forget to use "wb" flag, it will automatically replace all your \n with \r\n when you do fwrite, then you will try to debug for half a day your corrupted jpeg file, which totally never happened to me because I'm an experienced C++ developer who can never make such a novice mistake.
