Finding the Length (Index Numbers) of an Array in Perl

To get the number of pieces in an array:

@ko=("London","Paris","France");

$ji=$#ko + 1;

print $ji;

Which Prints:
3


-We named our array ko and stored 3 cities there.
-The pound symbol # after the $ but before the ko says "what's the last index number of ko?"
-The last index number is 2, remember index numbers start with 0.
-We added 1 to get 3.


Copy and Paste Perl Code:

#!/usr/bin/perl

print "Content-type:text/html\n\n";

@ko=("London","Paris","France");

$ji=$#ko + 1;

print $ji;

exit;
