Hello Coderanch forum members. This is my firts time ever posting on here. I'm a relative beginner who's taken a lot of introductory programming classes but never became good at any one of them (probably because I was on to the next one). That being said, now I pretty much don't remember any languages and all the courses I've taken were a waste of time. The language that I enjoyed the most was always Java! I'm here to improve as much as I can.

Here's my problem. I was tasked with creating a simple drivers exam test program that consisted of 20 questions that needed to be answered with an uppercase "A-D." At the end of the test I display whether or not you've passed or failed and the percent correct. The pass/fail portion works, but for some reason the percent correct always stays at 0%.

Can someone help me figure out what's wrong here?

Here's the code:

In integer math, what is numCorrect / 20 when numCorrect <= 20?

int / int gives an int result, so, for instance 9 / 10 has a result of 0. Converting to a double after the fact is too late. You need to have at least one operand be a double to start with.

Thank you Jeff. I knew it was something simple. It usually is. With all the math I've taken, percentages have always been an achilles heel of mine.

Everything works properly now.
