Operator[][] overload

Question

Is it possible to overload [] operator twice? To allow, something like this: function[3][3](like in a two dimensional array).

If it is pos

Answer 1

If, instead of saying a[x][y], you would like to say a[{x,y}], you can do like this:

struct Coordinate {  int x, y; }

class Matrix {
    int** data;
    operator[](Coordinate c) {
        return data[c.y][c.x];
    }
}
