菜鸟遇到菜问题哭了,帮帮忙把

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
#include<iostream>
#include<string>
#include<queue>
using namespace std;

class Weapon()
{

int _power;
public:

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)
{

return cout;
