In ruby you don't have to declare a variable (actually, you can't), you just 
assign a value to it. For example

a = [1, 2, 3, 4] 

stores an array containing the elements 1, 2, 3 and 4 to the local variable a.

By the way, ruby has a String class, so you don't need to use an array of char
to represent a string:

str = "text"

or

str = String.new "text"

If you're used to C programming, you can look at http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/to-ruby-from-c-and-c-/
to see a list of the differences between ruby and C/C++

I hope this helps
