i created a two dimensional matrix class which holds my object complex number. I am trying to overload the parenthesis () so that I can access and modify the value at specified location of the matrix. say matrix[a][b] = 5; and my_vals is a private member of the matrix class. What is the problem with my code //constructor & inlitilize dynamic array matrix::matrix(int rows, int cols) { complex** m_vals = new complex * [rows]; for (int i = 0; i...
