Question

I want to have something like this below:

template <class T>
struct Container{
 public:
  //[] operator
 private:
  T containment;
};

the containment is supposed to be an array with any selective number of dimensions as below:

Container<int[20][4]> obj;
Container<int[5][2][6]> obj1;
//etc...

And I want to implement the [] operator so that following assignments be possible:

obj[2][3]=6;
obj1[1][1][3]=3;
//etc...

But after a few tries I found myself stuck, how’s that possible?

Who thought reference would come into play here? me!
Thanks to Niki Yoshiuchi, The answer in exact framework that I want is as it follows:

template <class T, size_t N>
struct Container {
private:
 T containment[N];
public:
 T & operator[](size_t index) { return containment[index]; }
};

Container<int[3][3][3],2> obj;
obj[1][1][1][1]=7;
