Advanced Perl

Course Overview


During the lecture and lab portions of the Advanced Perl training course, you will learn how to write Perl code that makes use of best practices in Perl, and can therefore more easily be used by others. This includes using the built-in features of the language as well as learning and applying common approaches that make code more debug-able. Along with learning perl best practices, you will also learn how to write object-oriented perl programs, proper packing techniques in support of deployable products, and how to integrate Perl with C/C++ code.
