What is a multidimensional array?

If an array has more than two dimensions, it is called a multidimensional array. They are also called an array of arrays. For example, a 3-D array will look like this:

int 3darr[10][20][30] 

– this array can store 10*20*30 elements.

Assigning values

int ndarr[2][3][5] = {{{1,2,4,5},{5,6,7,9}, {6,5,4,3}}, {{1,1,3,4}, {2,3,4,6}, {5,6,7,8}}};

Accessing elements

To access each element, we need three nested loops, say i,j,k, so that we can get the value as ndarr[i][j][k]
