Please see my edited code above
Please have a look at How do I change/delete my post?, in particular, "It is uncool to update a node in a way that renders replies confusing or meaningless". But luckily I still had your original code sitting around:
sub get_max_index {
my $i, $imax;
for ($i=0; $i<@_; $i++)
{
$imax=$i if ($_[$i] > $_[$imax]);
}
return $imax;
}
my @arr = (1..10);
my $ans = get_max_index(@arr);
Other than that, Paladin has already pointed out the issue with the second my declaration inside the loop in your updated code. I just wanted to add that in general, one should not combine my with an if statement modifier, as its behavior is undefined (see Statement Modifiers).

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).

or How to display code and escape characters
are good places to start.
