So far I've not been able to get C++ running properly on VS-C , only VS which does not have it...?

@terne, Thanks for your feedback. ;-)
Corrected.

You should mark that as an issue.

If w>=h the ball will never be seen
if b<0 the ball will not bounce
if b>1 it will be seen infinite times from any window

Do you get this error here on the Codewars website or if you compile on your local computer?
On your local computer you need the Igloo testing framework.

I have the same error!! Don't know how to solve it. Please Help! Up vote if you have the same problem

From the description:

"For your convenience, a function named round1 has been defined for you. You can use it to round to the nearest tenth correctly (due to the inaccuracy of round and floats in general)."

Hopefully that clarifies the issue. Thanks.
