correctGuess = false?

Hey guys just wondering, why does the syntax starts off with: correctGuess = false?

Can someone explain why the correctGuess variable is set to false before we begin?

Because if correct answer started as true the code would never run :), this is just clarifying that the variable is false to start with. :)

I omitted declaring it in the beginning of my program and it ran okay except that my else statement wouldn't execute. So, declaring that variable as false in the beginning is quite important indeed! Reading this thread actually helped me debug why my else statement wasn't firing.
