Question

Which of the following is a loop invariant at the point at which the test for termination is performed in the following loop structure? X = 3
While (X < 5):
X = X + 2
A) X > 5
B)X < 5
C) X ≥ 5
D)X ≤ 5

Quizplus · Accepted Answer

A loop invariant is a condition that holds true before and after each iteration of the loop. In this case, X ≤ 5 is true before and after each iteration of the loop, as the loop continues while X < 5 and stops when X becomes 5 or greater.
