C#.NET — For the declaration below, what does intMyArr represent? int[][][] intMyArr = new int[2][][];

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:

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:

• A/B: Understate the dimensionality.
• D: Claims three inner arrays; only two are allocated at the outermost level.
• E: Says rectangular; jagged arrays are not rectangular by default.

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.
