I am working on some routines that manipulate 2D array. In order to
access individual elements, I define a operator [] member function.
However, operator [] only takes one parameter. In order to do

	A[i][j] = B[i][j]	// A and B are two 2D array classes

I do:

Tmp Array2D::operator [] (int i) {
	...
}

int& Tmp::operator[] (int j) {
	...
}

In this way, the problem is solved. 

Is there any better way to do this object array indexing?

Thanks

Joseph
