That code is private, and you should do it like this: int arr3d[][][] instead of: int[][][] arr3d I'm sorry, but I get all the languages mixed up sometimes

If you want that many elements, yes

Well, first you should understand 1D and 2D arrays. A 1 dimensional array is just a normal array (like int[] arr1d). A 2 dimensional array is an array, containing another array: [1, 2, [3, 4, 5]] You should declare it like this: int[][] arr2d. You can access its elements like this: cout << arr2d[2][2]; //Outputs 4 More than two dimensional arrays don't need explanation, it's pretty obvious after that. 3D: int[][][] arr3d = [1, [2, [3, 4, 5]]]; arr3d[1][1][2] == 5 ...

Is it like that int arr [2][2]={{1,2},/*0 row*/ {3,4}};/*1row*/ cout << arr [2][2]; // Outputs 0

Okay, I used brackets instead of curly brackets, but you get the point

I do know 2d arr very well, but 3d and 4D is little bit complex for me
