Array depth

Question

So im writing this code and i figured out i needed something,how to calculate array depth.There are multidimensional arrays,the problem is,how do i calculate an arrays deepest dimension.
e.g
arr=[ [ [1,2],[3,4] ],6,4,3,7];
as you can see this arrays dimension is three.but if i have arrays with several dimensions how do i find it?
e.g2
arr=[ [1,2],[3,4] ];
this is a 2d array,and so on.Im creating arrays with 20+ dimensions and i need a way of figuring out the arrays dimension,thanks.

In C++, it strongly depends and I need your exact data structure to tell you how it's possible or how to work around it.
