Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.
Ruby string to array split.
Typically methods with names ending in modify their receiver while those without a return a new.
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 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.
If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently.
This essentially turns the string into an array of equal length containing only one character strings one for each character in the string.
Ruby program that uses split parses integers line 100 200 300 split on the comma char.
A string object holds and manipulates an arbitrary sequence of bytes typically representing characters.
Values line split parse each number in the result array.
String objects may be created using new or as literals.
Typically methods with names ending in modify their receiver while those without a return.
In this article we will study about array join method you all must be thinking the method must be doing something which is related to joining the array instance with something.
Values each do v number integer v display number if it is greater than or equal to 200.

In ruby single quotes around a string means that escape characters are not interpreted.
In this case n is actually equivalent to n.
So if you want to split on n you need to change your code to use double quotes split n.
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.
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.
Here we are going to learn about the array join method with examples in ruby programming language.
