Chapter 18, Problem 18.8E

(Complex Class) Consider class Complex shown in Figs. 18.14–18.16. The class enables operations on so-called complex numbers. These are numbers of the form realPart $\text{realPart}+\text{imaginaryPart}\ast i$, where i has the value $\sqrt{-1}$

1. Modify the class to enable input and output of complex numbers via overloaded >> and << operators, respectively (you should remove the print function from the class).
2. Overload the multiplication operator to enable multiplication of two complex numbers as in algebra.
3. Overload the == and != operators to allow comparisons of complex numbers.

After doing this exercise, you might want to read about the Standard Library’s complex class (from header ).
