The Celsius to Fahrenheit function uses an assertion. What condition does this assertion enforce?

• A. Non-negative Temperature
• B. Temperature must be an integer
• C. Output must be Fahrenheit
• D. Inputs and outputs must be transformed atomically

Answer: (A)

It’s about validating the input the function will accept. An assertion here is used to enforce the allowed domain of input values, ensuring the function only runs when the input meets a certain condition. In this case, the assertion requires the input temperature to be non-negative. This means the function is designed to handle temperatures at or above 0 degrees Celsius, perhaps because the implementation uses an unsigned numeric type or follows a specific constraint of the system. This is the best fit because the conversion formula itself will produce a valid Fahrenheit value for any real Celsius input, including negatives. The assertion isn’t about the output unit (Fahrenheit is already the intended output by definition), nor does it require the input to be an integer, and it isn’t about atomicity of transformations.
