我没见过那样的错误，那程序代码还是从书上找的，运行结果怎么会那样？！求解，求解。

头文件应该这样#include <iostream>

楼上的不对啊，还是不行

兄弟,这有关系吗?不同的用法罢了...

vc6.0对友元支持不好，换编译器

dong哥,好久不见

to LZ:
打补丁(SP6)或自已定义名空间 或 换编译..

推荐:换编译,用GCC...

// s2.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "iostream"
using namespace std;
namespace Demo{
class Complex{
public:
    Complex(){real=0;imag=0;}
    Complex(double r){real=r;imag=0;}
    Complex(double r,double i){real=r;imag=i;}
    friend Complex operator +(Complex c1,Complex c2);
    void display();
private:
    double real;
    double imag;
};
Complex operator +(Complex c1,Complex c2)
{
    Complex c3;
    c3.real=c1.real+c2.real;
    c3.imag=c1.imag+c2.imag;
    return c3;
}
void Complex::display()
{
    cout<<"("<<real<<","<<imag<<"<<i)"<<endl;
}
}
void main()
{
    Demo::Complex c1(2.5,3.6),c2(2.0,3.8),c3;
    c3=c1+1.5;
    c3.display();
}

中学？

{cout<<"("real<<","<<imag"<<i)"<<endl;}是不是应该改成cout<<"("<<real<<","<<imag<<"<<i)"<<endl;
再加上楼上的名称空间，就通过了

我在这里....那位不是我~!
