Re: rand()

Peng,
 
Could you give me an example code? I want to randomly select X numbers of numbers from the @nums list. For instance, i want to randomly select 3 numbers from @nums i.e.  10000, 10005, 140000. How would you use srand to do this?
 
Would Math::TrulyRandom be a better solution since i want to use this function to randomly pick winners for a drawing contest. If so could some one kindly give me some example codes? 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";

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.


You may need srand before the rand function.
