构造函数成员列表：
Complex(double r=0,double i=0):real(r),iamg(i){}

应为:imag(i)

改了几处:
///////////////////////////////

# include<iostream>
using namespace std;

class Complex{
double real,imag;
public:
    Complex(double r=0,double i=0):real(r),imag(i){}
    double Real(){
        return Complex::real;
    }
    double Imag(){
        return Complex::imag;
    }
    Complex operator +(Complex &c);
    Complex operator +(double d);
    Complex operator =(Complex c);
};

Complex Complex::operator +(Complex &c){
    Complex temp;
    temp.real=real+c.real;
    temp.imag=imag+c.imag;
    return temp;
}
Complex Complex::operator +(double d){
    Complex temp;
    temp.real=real+d;
    temp.imag=imag;
    return temp;
}
Complex Complex::operator =(Complex c){
    real=c.real;
    imag=c.imag;
    return *this;
}

void main(){
    Complex c1(3,4),c2(5,6),c3(0,0);
   
    cout<<"c1 = "<<c1.Real()<<" + j"<<c1.Imag()<<endl;
    cout<<"c2 = "<<c2.Real()<<" + j"<<c2.Imag()<<endl;
    c3=c1+c2;
    cout<<"c3 = "<<c3.Real()<<" + j"<<c3.Imag()<<endl;

}
