以下是我按着一本书的代码打的,有47个错误,我看了几个小时没看出错在那
#pragma once

string GetName();
int GetPower();

bool operator > (const Weapon &other) const;
};
typedef priority_queue< Weapon,vector<Weapon> >Weapons;
//对流的操作支持
ostream &operator<<(osteam &cout,Weapon &weapon);





#include"Weapon.h"

using namespace std;

//让Weapon支持流的操作
ostream &operator<<(ostream &cout,Weapon &weapon)

#include <iostream>

是不是该加个.h啊?

那是C++的标准库,不加.h

class Weapon() 不写括号。class Weapon
流运算符<<间不用加空格

class Weapon()应该写成class Weapon,不用加括号。
ostream &operator < <(osteam &cout,Weapon &weapon);
去掉<<中间的空格。
其他的错误较简单。
我编译过你的程序了,按照上述办法可以编通。
