A class with methods in C#
C# interview exercise on Classes & Records, difficulty 1 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write Rectangle with Width and Height, Area(), CanHold(other) (true only when other is strictly smaller in both directions), and Square(size), a static factory method.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
