Re: Passing input through a hash then displaying results

You probably would want to do something like the following:

my $grade = <STDIN>;

my %scores = (
        "90" => "A",
        "80" => "B",
        "70" => "C",
        "60" => "D",
        "50" => "F");

my $letter_score = $scores{$grade};
if ($letter_score eq "A"){
 #return this
}

There is really no need to loop to lookup key/value pairs. I hope this helps. If you're trying to execute statements you may want to look into the eval function.

s;;5776?12321=10609$d=9409:12100$xx;;s;(\d*);push @_,$1;eg;map{print chr(sqrt($_))."\n"} @_;

What if he scored 89? That's why the looping is needed ( if you use a hash ).	[reply]

I would think for such a simple program no need to loop, but just simple if control statements would suffice. s;;5776?12321=10609$d=9409:12100$xx;;s;(\d*);push @_,$1;eg;map{print chr(sqrt($_))."\n"} @_;	[reply]

Sorry, I meant to say "That's why the looping is needed if you use a hash." Of course, you could just do `sub get_score { my ($score) = @_; return 'A' if $score >= 90; return 'B' if $score >= 80; return 'C' if $score >= 70; return 'D' if $score >= 60; return 'F'; }` [download]	[reply] [d/l]

How do I represent the values and keys in a loop or conditional statement?	[reply]
