How to print out the zombie's name and graveyard

Can you concatenate this without adding a string?

z = zombie.find(3)

puts z.name
puts z.graveyard

Is this wrong? It is only outputing the last one, graveyard.

Solution

  • You should use 

    puts "#{z.name} #{z.graveyard}"

    You might be wondering how this would get evaluated! You should look at Interpolation. The result of the expressions z.name and z.graveyard gets concatenated/inserted into the string. Any expression that goes into #{ } gets evaluated and inserted into the string
