Consider class Complex shown in Figs. 11.1–11.3. The class enables opera- tions on so-called complex numbers. These are numbers of the form realPart + imaginaryPart * i, where i has the value ?-1
a) Modify the class to enable input and output of complex numbers through the 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. c) Overload the == and != operators to allow comparisons of complex numbers. Fig. 11.1 Complex class definition.
// Complex class definition.
#ifndef COMPLEX_H
#define COMPLEX_H
class Complex
{
public:
Complex( double = 0.0, double = 0.0 ); // constructor
Complex operator+( const Complex & ) const; // addition
Complex operator-( const Complex & ) const; // subtraction
void print() const; // output
private:
double real; // real part
double imaginary; // imaginary part
}; // end class Complex
#endif
