Properties that validate and compute in C#
C# interview exercise on Classes & Records, difficulty 2 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write Temperature(celsius). Setting Celsius below -273.15 throws ArgumentOutOfRangeException, in the constructor too. Fahrenheit is a second property computed from Celsius (c × 9 / 5 + 32), and setting it updates Celsius through the same validation.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
