How do you use argument passing (@_) with a short example?

In Perl, argument passing is typically done using the special array `@_`, which holds the arguments passed to a subroutine. Here’s a short example to illustrate how to use it.


        sub greet {
            my ($name) = @_; # retrieve the first argument
            return "Hello, $name!";
        }

        my $greeting = greet("Alice");
        print $greeting; # Output: Hello, Alice!
