Hi,
(reposting this since i did not see the original in my newsreader or google)
I want to generate 10 numbers from 1..15 and put them in an array.
easy ?
while ($fill < 10){
$foo = int(rand(15));
unshift(@array, $foo);
$fill++;
}
print "the [EMAIL PROTECTED] is --> @array\n";
my problem is that many times the numbers repeat themselves in the array.
the @array is --> 5 10 8 3 0 13 14 9 0 10
how can i generate 10 unique (non repeating) numbers from a range to put in
the array ?
thanx.

Be patient when posting.
This will generate numbers between 1 and 15.
foreach (1..10) {
my $bar = int(rand(15)) + 1; # Since you want numbers 1..15 not 0..14
unshift(@array, $bar);
}
Since rand uses the internal clock (correct me if I am wrong) you're bound
to get repeated numbers. If you only want non-repeating numbers, run through
the array and only unshift if the number is not in the array already.
