Does this exist anywhere outside of C++?

They aren't the same thing so the comparison is weird.
endlhas aflushwhich is important when doing something like embedded work or RTOS development. If i was doing multiple lines they all were\nuntil the last line when i actually want to push the buffer.Obviously depending on the tuning of the compiler's optimization multiple flushes could be reduced but the goal should always be to write as optimal as possible.

Within reason.
Over optimization is a curse on getting done.

Who in the hell is using iostreams in an RTOS

Sometimes you work in a codebase that was decided on by others for reasons you don't know.

Several. Probably dozens

\n, because I ordered a newline, not a flush.
-
#define endl "\n"

If I'm writing C++, I'm usually optimizing for portability over performance, in which case I would prefer std::endl as it would yield the best results regardless of platform; it also keeps the end-of-line character out of other strings, making code just a little cleaner.
\n is for when I'm done pretending that anything that isn't Unix-like is OK, or I'm counting the cycles of every branch instruction.

Well, Java has System.lineSeparator so, maybe no?

Environment.NewLine might exist in C#
-
It might do. I encountered it last week as I needed it for a powershell script. So it exists in that at least
-
Microsoft really creating the problem and then forcing you to use their solution.

Endl is faster to type

What the heck is endl???
-
Instead of this:
C++
cout << "Hello world.\n";
You can do this:
C++
cout << "Hello world." << endl;

Alternatively:

p.s. The site isn't entirely mobile friendly
(I'm a cppref lover tbh)

Boy am I glad I don’t do C++ anymore. That string handling with the overloaded bitshift operator was wild.

From memory it's a way to declare a line ending after your string.

God bless your soul.

os.linesepLol jk none of my stuff runs on Windows anyway

Environment.NewLine()-
/* I'm new to this language so just imagine there is a new line here when it prints: */

\r\n gang

Are you a modem by any chance?

No, I'm a teapot

\r\n

If you write to a text (as opposed to binary) stream, \n produces \n or \r\n (or \r if old enough) depending on platform just fine.
Nobody should be using C++ anyway, but plenty of languages have silly system newline constants, which do nothing useful.
