我有两个类叫做“Person”，另一个叫做“Student”，我一直在追逐它，而我却无法让它编译。我从链接错误到现在的所有内容。学校：继承，显示我的班级工作？

我已经尝试在friendly2.cpp中的两个类，但我似乎继续追逐这个周围，请帮助。

person.h 
#pragma once 
#include <iostream> 
#include <string> 
using namespace std; 
class Person 
{ 
public: 
    Person() 
    {

    } 
    Person(string a, string b, string c, string d, string e, string f)
