I. When the user enters an integer
II. When the user enters an alphabetic character
III. After the user enters 100 numbers
A) I or II
B) II only
C) III only
D) II or III

Quizplus · Accepted Answer

The loop will stop when the user enters an alphabetic character (option II) or after the user enters 100 numbers (option III), whichever comes first. It will not stop when the user enters an integer (option I) as long as the input is valid (i.e. a double). Therefore, the best choice is option D, which includes both II and III.
