Let's say I have two files.. I want to compare them side-by-side and see what's added... anyone know?
Essentially they are the SAME file.
Beyond Compare
fc(file compare) in DOS?
Use diff on linux/unix or windiff on windows.
DiffMerge from SourceGear is also a nice tool, and it's free.
If you are looking for any *nix based system there is one built in called 'diff' as Raoul mentioned ... there is also 'compare' in the Windows command line which will do essentially the same (but not as thorough) ...
Otherwise you are going to need to be a bit more specific about what you want.

In my application i was supposed to include/access/bring another application which is installed in iPhone. I don't have the source code for the other application. I googled several references which says that i should include the source file of another application without ticking copy options. but the problem here is i don't have the source file of the application.
If you're hoping to "embed" another application so that it appears to be part of your own then you're going to be out of luck (i.e. this cannot be done) without the source.
If you'd like to launch another application (say facebook) then you can use URL schemes, there's a good reference here: http://wiki.akosma.com/IPhone_URL_Schemes
If you have something else in mind you'll have to rephrase the question as others have already said, it's not entirely clear.

Can I write an operating system using machine language directly?
Please give me a general idea or sources as to how to do it.
First, study the x86 or ARM instruction sets. Then, study up on operating systems. You'll see why it's not a great idea: it's like filling a sandbox one grain at a time with tweezers.
Yes, all you need is a lot of patience, sanity, and a binary editor.
After awhile you will realize why assemblers were created, which is the lowest level I would generally bother going to.
** yes you can but this is very diffecult for any one
and if you do this what make programmers and all design programming lanaguages to make things
easily comparing by machine code
and this is project as you ask
it's an OS written in machine code it's still under developing

note : your name is like my name iam glad to answer you
best wishes**

Advantage of closing file handle in Perl is that "$." gets
reset
cleans up buffer
gives command status
none
Please tell me the correct answer with explanation (if possible)
Read this close FILEHANDLE perldoc .
You can also look into perlvar for $.
There was an identical question posted to PerlMonks. You might look there at some of the excellent answers that question received: Why do we need to close filehandles?

just dig into perl and wondering if there is pycrust for perl.
Devel::REPL is the best. Run re.pl after installation.
The closest is probably perlconsole
Not exactly, but you can launch the interactive debugger after executing some trivial code by using something like:
perl -d -e 1
which simply drops you into the debugger after executing "1".
There's also http://www.sukria.net/perlconsole.html

What are the basic working principles of an antivirus program?
it matches patterns of known viruses with each file.
for example change the executable into a histogram and compare the similarity between that executable and known viruses.
another way is to scan for design patterns such as polymorphisism and comparing those to, this can lead to false positives (in very complex apps) but also catch unknown viruses.
A antivirus reads trough all files and searches for patterns of known viruses in the files.
