What else can I help you with?
Can you assign your scope to subroutione in perl ex like this my sub fun name....definition of function...?
Yes, in Perl, you can assign a scope to a subroutine using the my keyword to declare variables within the subroutine, allowing them to be scoped locally to that subroutine. For example: sub fun { my $local_var = "I'm local"; # This variable is scoped to the subroutine print $local_var; } This keeps $local_var from being accessible outside of fun, ensuring encapsulation within the subroutine.

Can you merge c and perl?
Yes, C and Perl can be made to talk together quite well. XS (http://en.wikipedia.org/wiki/XS_(Perl)) is the most widely used method for doing this - it allows you to write binding to C or C++ code so it can be called as a perl subroutine. Inline::C (http://search.cpan.org/~ingy/Inline-0.44/C/C.pod) is another method - it allows you to write C code inside Perl code and generates the necessary XS automatically. If you want to call perl code from C, you can link against libperl.
