You can easily navigate through arrays using a for or while loop that varies a subscript from 0 to ____.
A) Array.Length - 2
B) Array.Length - 1
C) Array.Length
D) Array.Length + 1

Question

Quizplus · Accepted Answer

Arrays in C# are zero-indexed, meaning the first element starts at index 0 and the last element is at index n-1, where n is the length of the array. Therefore, the correct upper bound for iterating through an array is Array.Length - 1. For example, if an array has 5 elements, the last element would be at index 4, so the loop should run from 0 to 4 inclusive. Choosing option B (Array.Length - 1) would ensure that all elements of the array are accessed without going out of bounds.
