Can someone briefly explain why ::
puts i.to_s +" :: "+arrayoutput[i]
yaml.rb:12: undefined method
+@' for " :: ":String (NoMethodError) from F:/RUBY/Source/yaml.rb:11:intimes’
but the addition of a space => puts i.to_s + " :: "+arrayoutput[i]
results in success.
some proir exp in java and cant remember requiring spaces in
concatentation. any replies welcomed!
