Using template to define n-dimension array

I understand that template <typename T> can be used to define a container class of type T at compile time.  For example:

template <typename T>
class C1dArray
{
T m_array[];
public:
// and methods that deal with 1darray operations
};

I can define C1dArray<int> and it will be an array of integers, C1dArray<double> and it will be an array of double.

So I started to define 2d array with the following definition:

template <typename T>
class C2dArray
{
 C1dArray<T> m_array[];
public:
 // and methods that deal with 2darray operations
};

Good, now I can use 2darray that contain any type I need.

Problem now, I like to define ndarray, but how to do it without create classes C3dArray, class C4darray, and repeat all the same methods that are coded in C2dArray?

void OnStart()

}

Very ingenious way of using template.  Thanks for the tip :-)
