This is worse:

for (my $i = 0; $i < $#names; $i++)
    {
    print $names[$i];
    }

Worse? That's the One True Way. However, for one-liners, horizontal alignment is preferable, i.e.: `for (my $i = 0; $ <= @names; $i++) { print $names[$i] }` [download] Given the C code. Hey, sometimes Perl is useful as a C prototyper. sas	[reply] [d/l]

The funniest part is that all three for-loops (parent, this, and child) are wrong (which only is a great defense of the whole point). The correct versions are `for (my $i = 0; $i <= $#names; $i++) { ... } # or for (my $i = 0; $i < @names; $i++) { ... }` [download] You guys had `$i < $#names` and `$i <= @names`. :-) My criteria for good software: Does it work? Can someone else come in, make a change, and be reasonably certain no bugs were introduced?	[reply] [d/l] [select]
