I have a header whose filename contains an embedded newline and I can't
seem to #include it successfully. I've tried
#include "my
file.h"
and
#include "my\nfile.h "
but neither works.
1. How can I achieve this?
2. Does the Standard limit the range of characters that can appear in
source file names? (for example, embedded tabs seem to be fine with an
actual tab character in the #include line)

It depends who you talk to. IMHO, yes, okay, C99 is the de jure
standard, but C90 remains the de facto standard for the time
being, because hardly any conforming C99 implementations exist.
C99 effectively standardises vapourware.
In addition copies of the C99 standard are readily available, which
does not apply to the C90 standard.

True (although you can get a C89 draft easily enough). But there's no great
advantage to having easy accessibility to a standard that hardly anyone has
implemented.

This is one of the few times I have to agree with Mark over

Yes, one of the few differences between the 1989 ANSi standard and the
1990 ISO standard is that the latter adds some sections (or splits up
some existing sections?) in accordance with ISO rules. I think that
ANSI C89 3.X.Y always corresonds to ISO C90 6.X.Y, and it's probably
the same for 4 vs. 7.
(I don't think I've ever seen a copy of the actual 1989 ANSI C
standard. ANSI adopted the ISO standard shortly after it was issued;
presumably they stopped printing the older version at that time.)

Hello,
I'm a little confused about where I should include header files and was
wondering whether there was some convention. Imagine I've written a
class foo and put the definition in foo.h and the implementation of its
member functions in foo.cpp (which obviously #inludes foo.h) and further
assume that it depends on a class bar which is defined in bar.h.
It seems that there are the following two scenarios:
