Describe error handling and exception management in Perl.

In Perl, error handling and exception management play a crucial role in ensuring the robustness and reliability of your code. Perl provides several mechanisms to handle errors and exceptions effectively. Let's explore these techniques in detail: 1. Error Reporting: * Perl provides a built-in variable called `$!` that holds the error message corresponding to the last encountered system or library operation. * You can use the `die()` function to report an error and terminate the program execution. It prints the specified error message along with the file name and line number where the error occurred. * Example: ``` perl`open(my $filehandle, '<', 'filename.txt') or die "Cannot open file: $!";` ``` 2.
