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

Methods

This code works in Workspaces. Any idea what the error means. For convenience, I've copy and pasted the question and error message below: "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. Bummer! Something doesn't look quite right. Double check your spelling & punctuation"

method.rb
def mod(a, b)
  puts "Dividing #{a} and #{b}"
  puts a / b 
  return "The remainder of #{a} divided by #{b} is #{a % b}"
end

mod(4, 2)

There are a couple issues:

  • You are explicitly calling the function. The code challenge never asked you to call the function, it only asked to define the function.
  • You are printing two messages that the challenge never asked you to print.
  • This is very minor, but even if you fix the above it won't pass because you are missing an extra period at the end of the string your returning.

i hope this helps :grin:

Happy coding! :tada:

Thanks. It was the period?. What's the difference between calling a function and defining a function?

Defining a function is kind of like assigning a variable to a value, expect you are "assigning a block of code to a name".

Calling a function is kind of like accessing the value of the variable, except you are executing (running the code inside) the function.
