Question

I have a hard-coded if loops that looks like this:

my $tp = 0;
my $fp = 0;
if (   $myhash{$pred}
        || $myhash{$pred1}
        || $myhash{$pred2}
        || $myhash{$pred3}
        || $myhash{$pred4}
        || $myhash{$pred5}
        || $myhash{$pred6} )
    {
        $tp++;
    }
    else {
        $fp++;
    }

How can I do that in for loops?

I tried the following but it give different result in total of fp and tp:

my $tp=0;
my $fp=0;

my @allpreds = ($pred,$pred1,$pred2,$pred3,$pred4,$pred5);

foreach my $allpred ( @allpreds ) {
        if ( $myhash{$allpred} ) {
            $tp++;

        }

    }
if ( !myhash{$pred} ) {
        $fp++;
    }

my $tp=0;
my $fp=0;
my $count=0;

my @allpreds = ($pred,$pred1,$pred2,$pred3,$pred4,$pred5);

foreach my $allpred ( @allpreds ) {
        if ( $myhash{$allpred} ) {
            $count++;

        }

    }

if ($count>0) { $tp=1; } else { $fp=1; }
