编译器本身出错了
类似于阅卷老师突然病亡

#include <iostream>
using namespace std;
class Complex
{public:
friend Complex operator + (Complex &c1,Complex &c2);
Complex(double r=0,double i=0){real=r;imag=i;}
double get_real();
double get_imag();
void display();
double real;
double imag;
};
double Complex::get_real()
{return real;}
double Complex::get_imag()
{return imag;}
//定义display输出函数
void Complex::display()
{cout<<"("<<real<<","<<imag<<")"<<endl;}
Complex operator + (Complex &c1,Complex &c2)
{Complex c3;
c3.real=c1.get_real()+c2.get_real();
c3.imag=c1.get_imag()+c2.get_imag();
return c3 ;
}
int main()
{Complex c1(3,4),c2(5,-10),c3;
c3=c1+c2;
cout<<"c3=";
c3.display();//调用display函数输出信息
return 0;
}
只是修改了几处加注释的地方，然后就实现了楼主你想要的功能

我也看了书上可以同函数输出c3，但也可以直接输出啊。而且那段代码还是需要把friend Complex operator + (Complex &c1,Complex &c2);这段删除才能正确运行，咋的呢

但把friend Complex operator + (Complex &c1,Complex &c2);删除了就不是那个错误了

求解

这问题，晕，哪里出错了

等我明天中午考完试，下午再解释给你听，问题不大的

好的，谢谢
