Consider the following snippet:
$Problem =~ /(\d*)\s(.)\s(\d*)/;
my $Number1 = $1;
my $Number2 = $3;
my $Operator = $2;
my $Answer;
if($Operator eq '+')
{
$Answer = $Number1 + $Number2;
}
elsif($Operator eq '-')
{
$Answer = $Number1 - $Number2;
}
elsif($Operator eq '*')
{
$Answer = $Number1 * $Number2;
}
elsif($Operator eq '/')
{
$Answer = $Number1 / $Number2;
}
$Problem is in a format like: 1 + 1 =
The $Operator can be one of the following: +-*/
The code works fine but I was wondering if there is a better (or at least more compact or even different) way?

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).
