I would like to point out that the numbers aren't as random as they could be. int(rand(1)) will always produce 0 as the output. int(rand(2)) will produce 0 or 1, int(rand(3)) will produce 0, 1 or 2 and so on. If you would like to produce multiple random numbers that are between 1 0 and 99 then try this.

use strict;
use warnings;

my @a;

foreach my $upper (1..10) {
    @a = map { int rand $upper } 1..10;
    print "@a\n";
}

print '*'x79, "\n";

foreach my $upper (1..10) {
    @a = map { int rand 100 } 1..10;
    printf "%2s ", $_ foreach @a;
    print "\n";
}
