Hi all

I would like to read all the characters in a string. For example
"123456" I need to read every digit separately.

thanks

For strings use

"123456".split(//)

for integers

"123456".split(//).map{|x| x.to_i}

"1234".each_char{|x| p x}

"1"
"2"
"3"
"4"
=> "1234"

"1234".each_char.map

=> ["1", "2", "3", "4"]

For me, glasses work extremely well. :wink:

For example

"123456" I need to read every digit separately.

For strings use

"123456".split(//)

Or

"12345".scan /./m do |s|
...
end

Cheers
