In above example cMatrix is a class object and you have not overloaded << operator. still "std::cout << cMatrix(1, 2)" statement is working fine without error. how is it possible?? Hi..

I did the overloading very similar to the way described here and the only way (that I found) to access my object is: (*object)(x,y) which looks quite ugly...

The "const" keyword does nothing, since POD gets passed by value. It makes more sense to write <pre>double& Matrix::operator()(int nCol, int nRow)</pre> Actually, he’s right that something is wrong here.

Here’s a noobish question:

double& Matrix::operator()(const int nCol, const int nRow)

Shouldn’t it be

double& Matrix::operator()(const int &nCol, const int &nRow)

?
