Syntax error at the end of input when all brackets match

Question

I realize this concern is almost always due to a simple mistype, but I can't for the life of me find the cause of this error. I've gone through the brackets multiple times and have checked if I'm missing any, but see nothing wrong. Excusing the disgusting way in which I initialized an array, what is wrong?

Your do {} while() loop is simply missing the while keyword.
