这是用c++实现的一个复数重载的实例

class Complex
{
	friend Complex operator+(Complex c1,Complex c2);
	friend Complex operator-(Complex c1,Complex c2);
	friend Complex operator*(Complex c1,Complex c2);
    friend Complex operator/(Complex c1,Complex c2);
    friend ostream &operator<<(ostream & dest,Complex source);
public:
	Complex(double=0,double=0);
	//Complex(){}
	void display();
	Complex & operator+=(Complex a);
    Complex & operator-=(Complex a);
    Complex & operator++();
	Complex operator++(int);
    Complex & operator--();
	Complex operator--(int);
    Complex & operator=(const Complex c1);
private:
	double real;
	double image;
};
