in reply to Calculate grades

I'm tempted to take this approach (assuming you're only dealing with single letter answers):

#! /usr/bin/perl use strict; my %test = ( question1 => 'a', question2 => 'b', question3 => 'a', ); #my hash of arrays with multiple answers my %answers = ( question1 => [ 'a' ], question2 => [ 'b', 'd' ], question3 => [ 'b' ], ); my $q_count = keys %answers; my $grade = 0; for ( keys %answers ) { $grade++ if "@{$answers{$_}}" =~ /$test{$_}/i; } print "You got $grade out of $q_count right.$/";

    Hello DamnDirtyApe
    Could you please decode for me the regexp, so I can adapt it?
    Actually some others test, have the answer type, not the option (one letter), so I could change the regexp. Thanks

      There's not really anything to decide. Putting an array inside quotes returns a scalar with the array contents, so if $foo == [ 'a', 'b' ], then "@$foo" == "ab". The regexp searches that string for the answer, so if the answer given was "b", what were essentially doing is "ab" ~= /b/i. This will match, and the correct grade counter is incremented.

      Make sense?
