Since Dave hasn't responded, maybe I can help. It's a common practice to set the value of a variable with it is created, this is known as "initialization". In this case, correctGuess is given the value of false to begin with because it represents the fact that a correct guess has not been entered yet. Then the value only needs to be set to true after the correct value is entered, and nothing extra needs to be done to it before then as wrong guesses are made.
