I am very new to ruby.I have a small doubt.
suppose i have a string called 'add',I want this to get saved when
given in any of the following conditions
it should be converted back in to small case and displayed back
how can i achieve this
string.downcase returns the downcased version of the string - it does
not affect the source object. If you want that reference to become
downcase you need
str = "ADD"
str = str.downcase
str.downcase will do what it's supposed to, but str will still be
whatever it was originally. If you're new to OO programming this one
can really confuse you.
