    Simple Question

    const Matrix Matrix::operator+(const Matrix& rhs) const;
    Can someone explain to me what each const is for in this function prototype?

    The first const means it returns a constant matrix, the one in the parenthesis means that the matrix passed will remain constant throughout the function, and the one at the end means that the class itself will not be changed throughout the function.
