How do you test code that uses temporary variables and scope?

Testing code that utilizes temporary variables and scope in Perl can be challenging but is essential for ensuring the accuracy and reliability of your scripts. Below is an example illustrating how to handle temporary variables and their scope effectively in a Perl program.


        # Perl Example: Scope and Temporary Variables
        use strict;
        use warnings;

        sub calculate {
            my $temp_var = 10;  # Temporary variable
            return $temp_var * 2;  # Use within scope
        }

        my $result = calculate();
        print "The result is: $result\n";  # Output: The result is: 20
