Here is issue with initialisation of array(@values = ();). It is reinitialising on every iteration of loop and ultimately storing last value. Use below hope that will fulfil your requirement

!#/usr/bin/perl use strict; use warnings; @number = qw(1 2 3 4 5 10 11 12 13 14); print "The values within the array are @number\n\n"; print "We will now print the square root of each number in the array a +s long as it falls between the range of 100-200 \n\n"; my @values = (); foreach $num (@number) { $sq = $num * $num; if ($sq >= 100 && $sq <= 200) { push(@values, $sq); } } print "Obtaining square values using foreach loop: @values\n";

[Corion]: Meh. My bank removed (part of) their CSV download facilities. Now I will either have to implement a full scraper or automate the download using the HBCI interface instead (or just get a new account elsewhere...)
[Corion]: On the upside, I spend a lot of time thinking this weekend about how to actually implement rate limiting for futures, and if things work out, maybe even loading a configuration from an external file makes sense
[Corion]: I've also found some interesting invariants that I have to think/write about more. A simple rate limiter will never change the order of the input, while a limiter that allows for parallel execution will change the order. But my API currently allows for bo
[Corion]: ... for both, and I'm not sure if I want to add the cruft from the parallel API (a token that you need to hold on to while you hold the lock) to the rate limiting API too, to allow seamless up/downgrades, or not.
