@haoNoQ  Thank you for the welcome and the helpful information!

Your suggestion sounds good to me.  I had actually started down this route initially of pointing out the logical error of using a variable before it is initialized. I changed direction because I was not sure where  the undefined values were coming from and how they propagate.

I prefer to focus on the logical error that a programmer should take action to fix, which in this case is using a variable or data before it is initialized.  I've found that programmers are often unfamiliar with standards terms like 'undefined behavior'.
