struct Circle

Section titled “struct Circle”
struct Circle : public Shape

Private, unlike RectangleF's and Triangle's data, because Shape's polymorphic accessor is center() and a field of that name cannot coexist with it. radius() is here to keep the pair symmetrical.

Circle() = default;
Circle(const Circle&) = default;
