我正在尝试应用在下面的C++类中学到的一些运算符加载的概念。
#include<iostream>
using namespace std;
class Point
{
private:
int x, y;
public:
Point(int, int);
Point operator+(const Point&);
friend istream& operator>>(istream& in, Point&);
friend ostream& operator<<(ostre
以下是错误:
In file included from /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/ios:39,
from /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/ostream:40,
from /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/
我想在模板类中重载<<操作符,并在模板类外部定义它。
using namespace std;
template <class T> class Child {
public:
friend ostream &operator << (ostream &Output, const Child &Object);
};
// What can I change to make my code work?
ostream &operator << (ostream &O
我编写了以下实用程序C++类。

我正在学习c++,但当我尝试从java代码到C++的翻译时,我总是遇到这个错误。我在java中有一些类,我必须将它们转换成c++代码(使用C++风格的编程)。我有一个文章类,继承自文章的ArticleUnitaire类,以及继承自ArticleUnitaire的类Ramette。所有的getter和setter都工作得很好,问题是当我尝试做与c++等价的toString时,它是operator<<重载的。让我向您展示代码和错误: Java代码:
public abstract class Article {
