Perl - while loop

A while loop will loop while a certain condition is true. For example, the following script . . .

use strict;
use warnings;

my $integer = 0;

while ($integer lt "5") {

. . . will produce the following output.

0 is less than 5 
1 is less than 5 
2 is less than 5 
3 is less than 5 
4 is less than 5
