I mean we could assign 'true' from the start?

1,122 PointsI am not sure what it is you're working on, but generally where a boolean such as "correctGuess" comes up its to validate some input to determine the next sequence of events in the program.
If we were to initialize the value of "correctGuess" to "true", it would assume that any input is "correct" and follow that sequence of events - which is obviously not good. I have an example of this being used in a simple Hangman Java app that I did for a college project that you can see below if you like.
In my case, it was used to determine whether or not the users guessed letter was a match. If so, correctGuess = true - which then updated the statistics and proceed to the next task.

Treehouse Moderator 145,860 PointsThat's correct, and I misread the question. :) Too early in the morning for me, I guess.
