array question

[Ruby Mokx]

Hey everyone I'm a 14 year-old beginner in ruby and I discovered that I
need to separate strings into arrays for a program that I am making.
For example, if I have the string 'abc', I'll want to make it into the
array ['a', 'b', 'c']. Is there any way to do this? I am using version
1.8.6, by the way. All help is welcome.

Thanks in advance!

The method you want is String#split:

'abc'.split(//) # => ['a', 'b', 'c']

Split takes a regular expression or string as its argument, and splits
on that pattern. The empty regular expression causes it to split the
string into individual characters.

There are some more bells and whistles to it but that's the basic
idea.

Here are two other techniques, just for fun:

all_characters = "abc".scan(/./)

all_characters=[]
"abc".each_char{ |x| all_characters.push(x) }

Hey Mokx, the answer has been given. Let me start to disturb you.
There's a difference between

str.scan /./ # and
str.scan /./u

Your enthusiasm ist delighting me but the real world is rough.
Cheer up.
