String To Array Ruby Split

I m trying to reverse words in an array of string variables but split doesn t seem to be working.

String to array ruby split. So if you want to split on n you need to change your code to use double quotes split n. Values line split parse each number in the result array. In this case n is actually equivalent to n. Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.

The split method does not change the original string. If an empty string is used as the separator the string is split between each character. I used scan instead of split to make a small improvement in this rubymonk module lesson second code from the bottom of the page. Testing in irb i get nomethoderror.

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. Unlike in c where single quotes denote a single character. 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. Private method split called for array which i m assuming has something to do with my program quietly doing nothing.

This essentially turns the string into an array of equal length containing only one character strings one for each character in the string. In ruby single quotes around a string means that escape characters are not interpreted. It will remove nothing at all from the original string and split on every character. 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.

Ruby program that uses split parses integers line 100 200 300 split on the comma char. Typically methods with names ending in modify their receiver while those without a return. If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently.
