The following fragment intends that a user will enter a list of positive integers at the keyboard and terminate the list with a sentinel:
The fragment is not correct. Which is a true statement?
(A) The sentinel gets processed.
(B) The last nonsentinel value entered in the list fails to get processed.
(C) A poor choice of SENTINEL value causes the loop to terminate before all values have been processed.
