g++ compile warning: extra tokens at end of #include directive

[japh]

I just started learning c++ and am at the point of using:

#include "myclass.cpp"

instead of having the class definition in the main file. But I am
getting this warning at compile time:

cat.cpp:4:19: warning: extra tokens at end of #include directive

The program compiles and runs fine, but the warning is puzzling and
concerns me. A google search returned lots of matches but no
solutions...

Any ideas? thanks

You'd put the interface/declarations in say "myclass.h" and include
that. The definitions are in "myclass.cpp" and get added to your compile
( and link ) list for the project.

5 The mapping between the delimited sequence and the external source
file name is implementation defined. The implementation provides unique
mappings for sequences consisting of one or more nondigits (2.10)
followed by a period (.) and a single nondigit. The implementation may
ignore the distinctions of alphabetical case.

Yeah - I guess I wasn't precise in describing the problem. I do have a
header file, etc. The problem seems to be with including files.
#include <iostream> works fine.

#include "myheader.hpp"; yields a warning but still works.
I'm using g++ on FreeBSD

Thanks

DOH -- pretty simple error:

I was typing
#include "myclass.hpp";

instead of
#include "myclass.hpp"

It turns out the semi-colon was the problem.

It turns out the semi-colon was the problem.

They're over-rated. Semi-colons are all just half-arsed.
