Code running on LINUX?

[anchitgood]

Hey, I have developed the following code and it is executing well on
windows. But I don't have LINUX installed on my system. I would be
grateful to you guys if you check whether this code is working fine on
linux. I know that C++ is independent of OS, but still check it on g++
compiler.
Thanks a lot in advance.

You might first want to test-compile it on Comeau Online:

Comeau has a reputation as one of the most standards-compliant compilers
around, and you may specify an "architectu re" to compile your code under.

yeah, its showing compile succeded on comeau link. Compile succeded on
every red hat platform and also on Linux alpha. So this has done the
job, isn't it?
Thanks a lot friends.

Just a nit, but compile succeeded doesn't mean that it will run.
You can still have undefined behavior that just happens to work
with the current version of the compiler you're using, at least
with the options you use to compile.

(Note that this really isn't a portability issue, per se, unless
it is a case of the code depending on behavior that actually is
guaranteed by your compiler, but not by the standard. It's a
sad fact of life that the fact that a program runs doesn't mean
that it is correct, even on a given platform.)

still have undefined behavior that just happens to work with the current
version of the compiler you're using, at least with the options you use
to compile.

More than a nit: I should have made clear that this establishes that the
code compiles, rather than (as the OP requested) that it "works fine" on
any particular platform.

case of the code depending on behavior that actually is guaranteed by
your compiler, but not by the standard. It's a sad fact of life that

given platform.)

I guess it could have been a portability issue if the OP's code happened
to call some system-specific library functionality (e.g. something POSIX-
or Windows-specific). The OP's system("cls") call is arguably system-
specific by definition - although the `system' part is perfectly
portable, of course... ;-)

Using explicitly implementation defined behavior, or undefined
behavior that is defined by your compiler or system, or
implementation specific extensions, or counting on additional
standards (Posix, Windows, etc.) create portability problems.
My point was just that in general, you can have problems when
"porting" even if the code doesn't have "portabilit y" problems;
the fact that is seemed to work on one system could be purely
due to change. The meaning of the string passed to system() is
one of these. (I might add that I haven't actually studied the
original code in detail, and so can't say whether it has or
doesn't have such problems.)

If all you need to do is to confirm that g++ compiles it, then install
mingw on Windows.
