Interpretation of Array dimensions

Question

What is the correct interpretation of an $array[a][b][c]$?

I have solved questions where $a$ is the number of layers, $b$ number of rows and $c$ number of columns. I have also seen questions where $a$ is the number of rows, $b$ is columns and $c$ is layers. Which one to follow to solve questions in GATE exam?

Can u plz put exact question?

Is it for row major, column major calculations?

Question where they took the first dimension as layers: https://gateoverflow.in/191590/3d-array?show=191590#q191590

Question where the last dimension was taken as layers: https://gateoverflow.in/29361/find-address-of-element-in-3d-array?show=29361#q29361

@mohit 

Actually there is no concept of layers,rows and columns it is just for our imaginary...

A[m][n][p] is actually p-element, n- is one dimensional array, m is two dimensional array...

If you want more clarity check my solution for the question https://gateoverflow.in/191590/3d-array

Answer 1

I think it depends on implementation but by default use first concept that is a is number of layers ,b number of rows and c number of columns

Sir, I asked this question on the GATE CS FB group. I got to know the following: "So if the question says RMO, then I should interpret the array as arr[number of layers][rows][columns] and if the question says CMO then I should take it as arr[rows][columns][layers]"
