Re: Using an array element as a loop iteratorby 2teez (Priest)

Of course, the answer you get is 2,4 and 6. Atleast that is what you have using the OP as showed by using the C-style for loop, which you supposed worked and indeed it worked since it gave you your desired result,
BUT did you check your "@a" variable after that to see it values? Please do and see what you have!
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
