Can someone help me please?

a) Modify the class to enable input and output of complex number via overloaded >> and << operators, respectively(you should remove the print function from the class).

b)Overload the multiplication operator to enable multiplication of two complex numbers as in algebra.

The instructions seemed pretty clear. What problems were you having?
