COMPLETE PERL Programming

Explore Perl programming from basic datatypes, conditionals, loops, and arrays to advanced text processing with regular expressions, CGI scripting, and practical extraction and reporting capabilities.

Explore Perl datatypes and operators, including scalars, arrays, and hashes, with integers, floating point, strings, and booleans; master arithmetic, assignment, increment, string concatenation, and array slicing.

Learn to use Perl operators and conditionals, including boolean and bitwise operators, and logical and not, along with assignment, equality, and comparison operators; use string concatenation in expressions.

Explore Perl control structures and subroutines, mastering if-else, loops (for, while, do until), nesting, and calling and defining subroutines with arguments and return values.

Explore file input/output in Perl, using predefined functions to read and write text files, manage hashes, keys, and values, and perform system calls and shell scripting tasks.

Identify common mistakes and debug Perl programs using debugging tools, performing stepwise error checks to identify uninitialized variables, misplaced punctuation, and syntax issues.

Explore how regular expressions enable pattern matching to search, extract, and validate text using symbols like *, +, ? and character classes across Perl and other languages.

Explore advanced Perl regular expressions, including pattern matching with grouping, quantifiers, character classes, alternation, and substitutions, and learn anchors to match from the start or end of a string.

Learn CGI programming with Perl to run server-side code, handle forms, and interact with databases using CGI scripts and the Perl CGI module, including response headers and mime types.

Explore CGI in Perl, defining subroutines, handling parameters, and printing outputs within Perl CGI scripts; learn form handling, hyperlinks, and debugging across platforms.

create and test perl scripts online using an online compiler, learn printing and string concatenation, hello world, variables, comments, looping to sum numbers, and lists with arrays.
