2、复数类输出实部和虚部

如题，要求实现：

1、复数类含两个参数的构造函数，一个为实部，一个为虚部

2、用GetReal() GetImaginary()返回实部、虚部，均为double型

#include<iostream>
using namespace std;
class Cmycomplex
{
private:
    double real,imag;
public:
    Cmycomplex(double r=0,double i=0);//这里可以给构造函数默认值，也可以重载构造函数 
    double GetReal();
    double GetImaginary();
};

Cmycomplex::Cmycomplex(double r,double i)
{
    real=r;
    imag=i;
}

double Cmycomplex::GetReal()
{
    return real;
}

double Cmycomplex::GetImaginary()
{
    return imag;
}

int main()
{
Cmycomplex  z1(2,3),z2,z3(3);
cout<<z1.GetReal()<<"\n";
cout<<z2.GetImaginary()<<"\n";
cout<<z3.GetReal()<<"\n";

}
