Re^2: How to get the TOTAL length/size of an array?

I totally agree with this The title of your question is misleading, because you want the total number of characters of an array of strings

But this is misleading or could be better phrased: The correct answer would hence be using Devel::Size to get the total memory of a deep data structure. Unless I misunderstood and by correct answer you mean to some other question!

The (total) number of characters in a deep structure (e.g. polyglot's array of strings) has nothing to do with the size of memory it uses (as in "space in RAM" etc.) except that when one increases the other increases and vice versa. In C it is even worse because of memory alignment when storing etc.

Consider this:

use Devel::Size qw(size total_size);
print size("A string");

Unless I misunderstood and by correct answer you mean to some other question! I rephrase, the most sensible answer to a general "TOTAL length/size of an array" is memory consumption measured by Devel::Size. Anything else is a matter of interpretation and lengthy definitions in the question. > has nothing to do with the size of memory it uses well in the case of strings it's roughly proportional. Maybe mostly off by 10% in average. And yes, I was nitpicking... :) Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery}	[reply]

well in the case of strings it's roughly proportional. Maybe mostly off by 10% in average.

And yes, I was nitpicking... :)
