Advanced Perl Programming

Course Summary

The Advanced Perl Programming training course is designed to demonstrate how to work with Perl to create production systems.

The course begins with an introduction of how to write Perl code that makes use of best practices in Perl, and can therefore more easily be used by others. Next, it explores the built-in features of the language as well as learning and applying common approaches that make code more debug-able. The course concludes with by examining how to write object-oriented perl programs, proper packing techniques in support of deployable products, and how to integrate Perl with C/C++ code.
