$param = k.chomp.split("\t")
How can I find the length of $param given that it is an array? actually when I'm writing
如果$param是一个数组，如何找到它的长度?其实当我写作
puts $param.class
I got the o/p like Array. Now how do I find the length of this array?
我有o/p的数组。现在我怎么求这个数组的长度?
I tried $param.length but it's not working.
我试着美元的参数。长度，但不行。

Ref Array class
Ref数组类
k = "This \t is \t just \t testing"
$param=k.chomp.split("\t")
array_length= $param.length #or $param.size
puts "length of $param is : #{array_length}"
o/p
o / p
length of $param is : 4
