3D Arrays

Understanding multidimensional array syntax in C++

This is an easy language-knowledge question that tests your familiarity with how C++ declares and initializes multidimensional arrays. It's the kind of foundational question interviewers ask to confirm you can read and reason about code without stumbling on syntax.

To solve it, you'll need to trace through the declaration, understand how memory is laid out for 3D arrays, and predict what values are printed. The question rewards careful attention to initializer semantics and array indexing—skills that become critical when working with large datasets or optimized data structures in production trading systems.
