How to use String Manipulation in Ruby

                        String Manipulation


Print a string :

irb(main):001:0> Puts " this is ruby"
If you find out the length of string :
irb(main):001:0> Puts "this is ruby ".length
Use uppercase letter print on screen :
irb(main):001:0> Puts " this is ruby" .upcase
