Re: How do I find the index of the last element in an array?

Just for any newbies...

Don't forget array indicies start at zero


@letterList = ("a", "b", "c", "d");

a is at position 0
b "   "     "    1
c "   "     "    2
...

Hope that helps out anyone who fell for the oldest trick in the book

Hmm....actually, that doesn't really help at all! If you want to know the index of the last element of an array, do this: `@letterList = ("a", "b", "c", "d"); #refer to the last array index #using '$#array' syntax: print $#letterList;` [download] This will, of course, output "3". You can also refer to the value of the last element of the array using negative indices, e.g. `$letterList[-1]` will also refer to "d". -- Microsoft delendum est.	[reply] [d/l] [select]
