Another 'x' option...
perl -Mstrict -we '
my @arr = (0..10);
printf("%d "x@arr, @arr);
'
__output__
0 1 2 3 4 5 6 7 8 9 10
or 'join' option...
perl -Mstrict -we '
my @arr = (0..10);
printf("%s", join(" ", @arr));
'
__output__
0 1 2 3 4 5 6 7 8 9 10
EDIT:
Yes, I know I could build an output string by looping over the array, but I am trying to learn about sprintf. :)
Sorry if 'join'-ish type option above was something OP already tried...

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
