In C and C++
\nis the newline character to be used in strings inside the application. The conversion to the platform-specific newline sequence is done by the IO streams when opened in text mode (i.e. not in binary mode).Notice that this is true for the standard library, but may not hold for particular APIs – e.g. I remember that some Windows controls needed an explicit CRLF to work correctly.
As for Java, I may be wrong (I almost never worked in Java), but from what I can see from the documentation the streams don’t perform any translation; instead, you can use
System.lineSeparator()to obtain the current platform’s line separator. Using this information,BufferedWriterprovides a handynewLinemethod to output a newline to the underlying stream.
