Question

Quizplus · Accepted Answer

Arrays allow for traversal through the list structure by managing a subscript (index), which is a fundamental operation. However, the length of an array is fixed upon its creation in many programming languages, making B incorrect. Adding or removing an element at a specific position in an array typically requires shifting the other elements to maintain the array's continuous indexing, making C and D incorrect.
