Question

What functional feature does the code below best exhibit

(define start-engine (lambda()
(error-detection(wheel-velocity(wheel-sensor))(body-velocity))))

a.use local variables to store intermediate values
b. procedures are first class objects
c. use recursion instead of loop
d. sequential processing of componenets

Answer 1

The code provided demonstrates sequential processing of components, as it defines a function that calls several other functions in sequence.

Step-by-step explanation:

The code snippet you provided exhibits the functional feature of sequential processing of components. This feature is apparent because the code defines a start-engine function that sequentially calls other functions. It first calls wheel-sensor to get the wheel velocity, then passes that to the wheel-velocity function, and finally passes the result to the error-detection function along with the body velocity. Neither of the other options provided (use local variables to store intermediate values, procedures are first class objects, use recursion instead of loop) are clearly supported by the snippet as it is presented.

The code snippet provided exhibits the functional feature of using local variables to store intermediate values. In this code, the intermediate values are the results of the function calls wheel-sensor, wheel-velocity, and body-velocity. These results are passed as arguments to the error-detection function. By using local variables to store these intermediate values, the code improves readability and organization.
