Difficulty: Easy
Correct Answer: A 3-D jagged array containing 2 two-dimensional jagged arrays.
Explanation:
Introduction / Context:Jagged arrays are arrays of arrays. The number of bracket pairs indicates the depth, and the first allocation creates the outermost array only.
Given Data / Assumptions:
int[][][] signals a three-level jagged structure.new int[2][][] allocates the outermost array with length 2; inner arrays are uninitialized (null) until created.Concept / Approach:This declaration creates a 3-D jagged array, where each of the two outer slots will later hold a 2-D jagged array (int[][]). It does not define rectangular dimensions; shapes of inner arrays can vary independently.
Step-by-Step Solution:
Identify depth: three bracket pairs → 3-D jagged.Outer length: 2 (fromnew int[2]).Inner arrays: each element will be an int[][] (2-D jagged) created later.Verification / Alternative check:Attempt to access intMyArr[0] after allocation: it is null until assigned a new int[][]; this confirms jagged, not rectangular, behavior.
Why Other Options Are Wrong:
Common Pitfalls:Assuming new int[2][][] initializes all levels; only the first level is allocated.
Final Answer:A 3-D jagged array containing 2 two-dimensional jagged arrays.
