difference between carriage return(\r) and new line(\n)

[vishalsharma]

hi

can any body explain what is the difference between carriage return (\r) or you can say Enter and New Line character(\n)..

both are treated as same..

in .net(c#) if you write a file using stream writer
like this.

StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\r\n------\r\nHow are You.");
writer.Close();

will print this..

Hello
------
How are You.

or if you use
StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\r------\rHow are You.");
writer.Close();

then the results will again be same as

Hello
------
How are You.

and finally if you use like this
StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\n------\nHow are You.");
writer.Close();

then again the result will be same as

Hello
------
How are You.

then what is the difference between \r and \n

please explain

Hi,
this seems to be a hazy subject...
check out this link
http://channel9.msdn.com/ShowPost.aspx?PostID=169419

and esp this (second last post in the thread)

\r\n is the Windows line ending. (0xDA; CRLF)

\n is the UNIX line ending (0xA; LF)

Historically old-school "Classic" Macs used \r (0xD; CR) (but they called it \n to confuse people)

You'll see bare CRs only from Mac users who are using a Classic browser.
