                        circle.Draw();
                        break;

its an assignment I already turned in but would like some feedback as to why my check for radius boundary has been very wonky, i still had exceptions being thrown for it being out of bounds on my screen.

Take a look at Math.Min() and Math.Max(). Can you think of a way to only generate a radius once, guaranteeing that it will fit? Also, what happens when x or y happens to be 0?

BI || CrescentThiefOP•2y ago

if x or y is zero then i would have to have the code rerun the generation of the x and y thanks for the insight
