Ruby Ruby Basics (Retired) Ruby Methods Method Returns: Part 2

Posted by Kyle Merrick

What is the answer here? For someone reason, I'm completely stumped on the proper syntax here.

In the previous challenge, we wrote a method that returned the remainder of two arguments when divided. That's cool, but it would be nicer if the method returned the remainder in a nice full sentence. Use string interpolation to return the remainder inside the sentence “The remainder of a divided by b is c.” where a is your “a” variable, b is your “b” variable, and c is the value of a % b.

method.rb 
def
  puts "The remainder of #{a} divided by #{b} is #{c}:"

end

Hey Kyle,

You're on the right track, but there are a few issues preventing the challenge from passing:

  1. First, for some reason you have deleted part of the code that was pre-loaded, specifically the method name and definition.
  2. You are trying to interpolate a value for c, but c is not defined anywhere. The question doesn't want you to create a new variable (although you could), but rather, the challenge wants you to do the calculation inside of the interpolation.
  3. You have a colon at the end of the sentence instead of a period (challenges are very picky).
  4. The challenge explicitly asks you to return the string, but you are using puts.

You will need to reset the challenge to get back the deleted code, and with these hints in mind, you should be able to pass the challenge.

Keep Coding! :) :dizzy:

Got it! Thanks for taking the time to explain it, I really appreciate it. I think looking at it with fresh eyes also helped my cause.

Should look like this,...

def mod(a, b) c = a % b "The remainder of #{a} divided by #{b} is #{c}." end
