Hello again ruby community!I just learned how to add two arrays(I know, i know).My program looked like thisarray1=[1,2,3]array2=[4,5,6]array_sum=array1+array2I thought pretty simple stuff, they are combined. However, now i amlooking to define that code as a method and I do not understand how tocreate the correct number of arguments, so when the method is calledback it gives me my array_sum.I have been trying many different variations, but it has now come downto I am not sure if my defining is wrong or my code in the method isincorrect.I want to say it is something such asdef please_work()array1=[1,2,3]array2=[4,5,6]array_sum=array1+array2endputs please_work(array_sum)i ended up fiddling around and getting it to output [1,2,3,4,5,6], butmy syntex said i did not have the correct number of arguments. Also,sometimes i get array_sum is not a defined variable. If I am defining itin the method, shouldn't it be defined if i call the method again?thanks taking a look at my questionalex--Posted via http://www.ruby-forum.com/.--You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.To unsubscribe from this group and stop receiving emails from it, send an email to rubyonrails-talk+unsubscribe@googlegroups.com.To post to this group, send email to rubyonrails-talk@googlegroups.com.To view this discussion on the web visit https://groups.google.com/d/msgid/rubyonrails-talk/bc0aa129b0271b8f7159b64b5d0f6fd8%40ruby-forum.com.For more options, visit https://groups.google.com/groups/opt_out.
