Though he's probably not allowed to use CPAN in his course work, it's too bad. Because if he could, he would be able to use IO::Prompt::Tiny or IO::Prompt::Hooked to simplify the prompting for input. In fact, though it's like calling in the artillery when a fly swatter is needed, ExtUtils::MakeMaker is a core module, and comes with the prompt function.
use ExtUtils::MakeMaker 'prompt';
my $value = prompt "Please enter something.", "asdf";
print "$value\n";
The first argument is what to say to the user. The second argument is what default to assume if the user just hits enter (or if there's no terminal).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
