String To Array Ruby Split

I used scan instead of split to make a small improvement in this rubymonk module lesson second code from the bottom of the page.

String to array ruby split.

Testing in irb i get nomethoderror. Ruby program that uses split parses integers line 100 200 300 split on the comma char. Unlike in c where single quotes denote a single character. The split method does not change the original string.

Values line split parse each number in the result array. It will remove nothing at all from the original string and split on every character. The split method is used to split a string into an array of substrings and returns the new array. Private method split called for array which i m assuming has something to do with my program quietly doing nothing.

Usr bin env ruby str foo bar baz puts str split. Typically methods with names ending in modify their receiver while those without a return. A string object holds and manipulates an arbitrary sequence of bytes typically representing characters string objects may be created using string new or as literals. Values each do v number integer v display number if it is greater than or equal to 200.

Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object. This essentially turns the string into an array of equal length containing only one character strings one for each character in the string. If split s first argument is a string the characters in that string are used as a string separator delimiter whereas in comma delimited data the comma is used to separate data. In ruby single quotes around a string means that escape characters are not interpreted.

String objects in ruby have a method called split it is similar to the split function of perl it can cut up a string into pieces along a pre defined string or regex returning an array of smaller strings. I m trying to reverse words in an array of string variables but split doesn t seem to be working. So if you want to split on n you need to change your code to use double quotes split n.
