One of the main things enforced by strict is that you need to declare your variables, typically with my.

Here is the code you provided, in the <code> tags:

#use strict; #use warnings; open (FILE, 'german.txt'); @words = <FILE>; $num = int rand(@words); ($article, $noun) = split(/ /, $words[$num]); chomp($noun); print "Who is the article of $noun:"; chomp($resp = <>); if ($resp eq $article) { print "Correct!"; } else { print "The correct answer is $article!" }
A few problems:
  1. You need to declare the variables with my
  2. You should check that the file was opened successfully
Here is a corrected version
use strict; use warnings; open (FILE, 'german.txt') or die "Failed to open german.txt - $!"; my @words = <FILE>; my $num = int rand(@words); my ($article, $noun) = split(/ /, $words[$num]); chomp($noun); chomp($article); print "Who is the article of $noun:"; my $resp = <>; chomp $resp; if ($resp eq $article) { print "Correct!"; } else { print "The correct answer is $article!" }
