Easy way to go through a 3 dimensional array?

I can keep up with 2d arrays but 3d arrays seem very confusing to go through with loops. Any suggestions or alternatives?

Multidimensional arrays are easy. Code the inner most array access first: int arr[4][3][2] for (i = 0; i < 2; i++) arr[][][i] = 0; Add the next level around it: int arr[4][3][2] for (j = 0; j < 3; j++) for (i = 0; i < 2; i++) arr[][j][i] = 0; Continue adding nesting until done: int arr[4][3][2] for (k = 0; k < 4; k++) for (j = 0; j < 3; j++) for (i = 0; i < 2; i++) arr[k][j][i] = 0;

Try to imagine it as a structure. 1D Array: list of elements 2D Array: paper with rows and columns 3D Array: stack of papers with page numbers 4D Array: binder with multiple paperstacks Or in a geometric way: 1D: line 2D: plane 3D: Cube 4D: lined cubes 5D: plane of cubes 6D: cube of cubes I don't actually know if this helps you though :D
