Why is the if (correctGuess) at the end is equal to true?

I am wondering why when you call the if (correctGuess) later in the code why is that not equivalent to correctGuess = false; at the top? I was under the impression that the only way to call 'correctGuess = true' is either typing it out like that or '(! correctGuess)'... can anyone help explain this??

Can you post code? I don't see what you are talking about in the video workspace.

The assignment on line 15 changes the value of "correctGuess" to "true'. That's what happens when the number guessed matches the random number.

The only way for "correctGuess" to still be false at the end is if the loop ends because the count got to 10 and a match was never entered.

if you dont set correct guess to false does that mean later on a conditional statement will assing a boolean value to it?

It is set to "false" to begin with because it might not get set later on.

I am agree with Brian, if the break is present, now the correctGuess variable is useless... am I wrong?

No, it indicates if the loop ended from running out of turns (false) or because the right answer was given (true).
