Re: rand()

Aruna,
 
That helps but how would i just get back an X number of random numbers because @nums could be in the hundreds of unique numbers. For instance, i just want to randomly pickout 4 numbers from a long list of unique numbers in @nums, how would i do that? Thanks.

Hi all,

How do I use the rand function to print out more than one random number
for an array? In the example script below i have an array @nums with a list of
numbers; how do i print out more than one random numbers from that list
(@nums)? Thanks.

#!/usr/bin/perl
use strict;
use warnings;
my @nums =
("10000","10002","10004","10005","10006","140000","1500000");
my $randnum = $nums[rand(@nums)];
print "$randnum \n";






#!/usr/bin/perl

use strict;
use warnings;
my @nums =
("10000","10002","10004","10005","10006","140000","1500000");
print "@nums[0..rand(@nums)]\n";
