Insert the following statements at the top of your C code:

#! /usr/local/bin/perl

use strict;
use warnings;

Add +x to the file permissions.

Execute the file, correct all of the warnings and errors, and 'Hey Presto' you have Perl code. (Now you will need to read up on the differences between the f-subroutines and their real counterparts, but I have to leave something as an exercise for the Student.)
