So we set isAcceptable = false does that mean (! isAcceptable) = true ?

is false then (! isAcceptable)
is true.

4,662 PointsI was looking for this very question.
I think I got it, but just to check:
The idea of a do-while loop is that it executes the code in the "do" block until the expression in "while()" evaluates to "false" (essentially: keep doing this as long as the condition is true), right?
So, in our case, we have the "isAcceptable" boolean set to "false" and the statement in "while" is going to be true as long as "isAcceptable" stays false, right?
Meaning that the only way to stop the loop is for a letter to pass the validation and normalization, which would change "isAcceptable" to true, which would make the expression in "while()" false?
Sorry if this is redundant, but this actually broke my brain for a while, especially since I wasn't entirely sure how do-while worked. :)

8,100 PointsThanks Chris. So in the do-while loop does it mean that as long as isAcceptable is false it will keep on looping until it flips to true? Right?
