My program should display multiples of a chosen integer between 200 and 100, For example, if a user enters 5, the results would be 200 195 190 etc... The program must use a while loop If anyone can help me I would appreciate it. Thanks. Here is my code 
#!c:\Dwimperl\perl\bin\perl.exe

use strict;
use warnings;

#### prompt a user to enter an integer
print "Enter an integer ";
my $integer = <STDIN>;
chomp $integer;

my $i = 199;

### use either a while loop or an until loop to count down from 199 to
+ 99
while($i >= 99){
     ### display all multiples of the integer

     print $i - $integer . "\n"; 
     --$i;    
}
