One of my friend is facing problem, where in vim the end of line is

Is there some setting that is causing to show some character at the
end of line?
this can happen when you edit a with DOS line endings, i.e., carriage
return plus line feed, the 'fileformats' does not contain DOS, but only
UNIX or MAC, and if the 'isprint' option contains 13 (the numeric code
for carriage return) or 10 (the one for line feed) or a range including
13 or 10.
In this case Vim wants to show you that there is an additional carriage
return or line feed. Normally they would be displayed as ^M or ^J, but
because the corresponding numeric value is included in 'isprint', Vim
tries to show a glyph from the current font. Most fonts don't have a
glyph for control characters, so a substitue is chosen -- which, e.g.,
on Windows happens to be a rectangle.

Yes, and it could also happen with
:set fileformats=dos,unix
if you try to edit a file whose last line lacks an end-of-line. Then Vim
will treat that file as Unix-style and display the carriage returns
which are part of the Dos-style line endings (normally as ^M, but as a
hollow box, reverse-video question mark, or other placeholder if
declared "printable" by the 'isprint' setting). If this is the case,
then make sure that you have (or that your friend has) a Vim version not
earlier than 7.2.040 (the latest to date is 7.2.411) and open the file with
:e ++ff=dos filename
This way, either CR+LF ("Dos-style" EOL) or LF-only ("Unix-style" EOL)
will be seen as an end-of-line when reading, and all lines (including
the last one) will get CR+LF when writing.
Note that some other programs such as Notepad have been said to
(mistakenly) display an "empty line" after the last line when the latter
has a proper end-of-line marker.
Best regards,
Tony.
