question in array of array ref.

cc96ai

$mydata = [["Item", "Category", "Price"],
["Nails", "Hardware", "5.25"],
["Shirt", "Clothing", "23.00"],
["Hammer", "Hardware", "16.25"],
["Sandwich", "Food", "5.00"],
["Pants", "Clothing", "31.00"],
["Drinks", "Food", "2.25"]];

how could I get the size of ref ?
print @{$data}; seems not

and how could I loop ref ?

thanks

You would want to look into casting, for example @{$mydata} and/or de-referencing, like $$entry[0].

print "Ordinal of \$mydata is " . scalar(@{$mydata});
print "\nFirst of each:\n";
foreach my $entry (@{$mydata}) {
   print $$entry[0] . "\n";
}
