Perl Programming

A good Perl programming assignment for students should:

Be challenging yet achievable: The assignment should be challenging enough to help students develop their skills, but not so difficult that they become discouraged or unable to complete it.

Be relevant to the course material: The assignment should be directly related to the concepts and topics covered in the course, helping to reinforce the student's understanding of the material.

Encourage creativity and experimentation: The assignment should provide opportunities for students to think critically and creatively, allowing them to explore different approaches to solving a problem.

An example of a Perl program is a script that reads a text file, performs a search and replace operation, and then writes the modified text to a new file. Here is an example of what the Perl code for such a script might look like:

Copy code
#!/usr/bin/perl

use strict;
use warnings;

my $file = 'input.txt';
open my $fh, '<', $file or die "Could not open $file: $!";
my $text = do { local $/; <$fh> };
close $fh;

$text =~ s/old_text/new_text/g;

my $out_file = 'output.txt';
open my $fh_out, '>', $out_file or die "Could not open $out_file: $!";
print $fh_out $text;
close $fh_out;

Perl programming assignments for students are important for several reasons:

To develop problem-solving skills: Perl programming assignments help students develop problem-solving skills by providing them with challenging problems to solve. This helps students to learn how to break down complex problems into smaller, manageable tasks and to develop logical and efficient solutions.

To reinforce course material: Perl programming assignments are directly related to the concepts and topics covered in the course, which helps students to reinforce their understanding of the material and to apply what they have learned in a practical setting.
