Others have offered varied solutions. Alternatively, you can use
splice.
Once you have read all the names into an array, you can loop through that array to gather items 3 at a time:
while(@names) {
my ($i, $j, $k) = splice (@names, 0, 3);
printf('$i is %s, $j is %s, $k is %s', $i, $j, $k);
print "\n";
}
Note that if you have
strict or
warnings enabled, you will get errors like:
"Use of uninitialized value $k in printf". You can add error/null checking here to handle all of these. This would also mutate the
@names array - keep a defensive copy around. :-)
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
