Question

Let’s say I declare this:

int [a][b][c];

Does a stand for the level/page, b the row and c the column?

Or can it be anything I want it to be i.e. a stands for column, b stands for page, and c stands for row (since data is just data and a cube can be abstracted any way)?

Answer 1

Anything you want in any order you want, the designations row and column are just convention. The layout in memory will be http://en.wikipedia.org/wiki/Row-major_order in C++, That part can’t be changed.

How you iterate through the elements will have an impact on performance in many cases. You want to change the rightmost index in your innermost loop to move through memory sequentially.
