Here's a few hints:

  • the variable "secret" should be declared before the loop
  • the welcome message will come after the loop
  • the loop body will be between the "do" and the "while"
  • there won't be a code block after the "while"

i got through but i don't understand the logic behind. How was the do/while loop better in that scenario? https://teamtreehouse.com/stevenparker

The main advantage of the do/while loop is that it elminates the redundant "prompt" statement.
