定义复数类 可完成复数基本运算 并利用它进行复数运算 要求具有加减算法

#include class Complex{ private:double real;double imag;public:Complex(double real=0,double imag=0);Complex();void SetComplex(double real=0,double imag=0);void Print();Complex Add(const Complex &c);Complex Subtract(const Complex &c);};Complex::Complex(double real ,double imag){this->real=real;this->imag=imag;}Complex::Complex(){}void Complex::SetComplex(double real,double imag){this->real=real;this->imag=imag;}void Complex::Print(){if(imag>=0)cout
