What are Perl modules and how do I use them

Perl modules are reusable packages that can contain subroutines, variables, and other resources to help you streamline your Perl programming tasks. They encapsulate functionality and allow you to avoid code duplication, making your code more modular and easier to maintain. To use a Perl module, you typically use the `use` statement followed by the module name.

Below is an example of how to use a simple module in Perl:

# Example of using a Perl Module use strict; use warnings; # Using the built-in ITK module use Math::Complex; # Load the Math::Complex module my $a = Math::Complex->make(1, 2); # Create a complex number my $b = Math::Complex->make(2, 3); # Create another complex number my $sum = $a + $b; # Add the two complex numbers print "The sum is: $sum\n"; # Print the sum
