Here are a few hints:

  • the argument to a readLine would normally be a question to show to the user
  • when using printf, the substitution token(s) must be part of the template string (inside the quotes)
  • for each token used in a printf, there should be another argument to supply the value to fill in
  • when challenges ask for specific text, be sure to copy it exactly (including case, spacing, and punctuation)
