Fundamentals for Perl Programming

Course Code - IB-102 Duration - 1 Day

This hands-on course gives those with limited programming experience, an introduction to basic programming constructs used in the Perl language.

The course provides prerequisite knowledge for the course 'Perl Programming & Applications' ('IB-103') for those without experience in a C-like language.

The course covers program structuring and fundamental programming constructs: input and output, variables, conditional processing, loops and subroutines. In particular, it explains how these constructs are implemented in Perl.

Who Should Attend

Anyone who wants to attend the course 'Perl Programming & Applications' ('IB-103') and who does not have experience in any language that uses C-like syntax such as C, C++, Java or JavaScript.

Programmers who have experience in languages such as Visual Basic, Pascal or Delphi are well-advised to attend this course prior to attendance on 'Perl Programming & Applications' ('IB-103').

Prerequisites

Previous programming experience in any structured language is required.
