Are there really any difference (beside the index of element), between i.e x[2][3][4] or x[2][4][3] or x[2][12] or x[24] ?

Answer 1

Yes x[2][3][4] is different from x[24], in x[2][3][4] x is multidimensional array, and in other case x is single dimensional array.

Answer 2

@Vishal Prajapati
Yes, I understand that. But wether its single or multidimension, array is just collection of variables right? So what really the difference between single and multidimension array that hold the same amount of variables (in my examples 24 variables)?
I mean beside the indexing ofcourse.
