Now that I now almost a dozen different languages. Its hopeless in remembering the syntax. Awesome post and example! Thanks.

The pickaxe was entirely opaque on this subject and I now know how to do if-else’s neatly AND switches all with one structure.

Many thanks.

I believe the problem is your case statement is comparing a string with an integer. Type “value=gets” into IRB and then type the number 1. You’ll see that IRB tells you the result is the string “1\n”.

To fix this, convert the value to an integer before comparing it to 1, 2, or 3:
case value.to_i

Hope that helps!

My options are
1.List – List the XML file.
2.Add – Add an element into the XML file
3.Delete – Delete an element from the XML file
i want to put these three options in case statements and select one based on the user input.
value = gets (receive input from the user)
case value
when 1: list (invoke list)
when 2: add (invoke add)
when 3: delete (invoke delete)
else puts “exit”
When i give input as 1,2,or 3 only else statement is executed.
Is the syntax is right?what corrections i have to do ?

I assume you mean in a Rails View. The trick is to use %=, not %. Here’s an example:

<%=
  case @results
  when nil then "No results"
  else @results.join ", "
  end
%>
