我正在尝试编写大学作业的代码，但似乎在编译时遇到问题，我已经对错误进行了 Google 搜索，我看到的修复不适用于我的代码。非常感谢您的帮助。

错误代码如下:

Error 1 error LNK2019: unresolved external symbol "public: __thiscall user::user(void)" (??0user@@QAE@XZ) 
referenced in function "void __cdecl `dynamic initializer for 'player''(void)" (??__Eplayer@@YAXXZ) 
C:\Users\obinyans\Documents\Visual Studio 2010\Projects\test\test\Challenge 1.obj

下面是我的代码的拷贝:

#include <iostream>
#include <string>
#include <math.h>

using namespace std;

void storeinfo() ;
void showinfo() ;


class user 
{
    string firstname, lastname, currentteam, position, status ;
    int age ;
public:
    user();
    user(string, string, string, string, string, int) ;
    void setFirstName(string fname)
        {firstname = fname;}
    void setLastName(string lname)
        {lastname = lname;}
    void setCurrentTeam(string cteam)
        {currentteam = cteam;}
    void setPosition(string pos)
        {position = pos;}
    void setStatus(string stat)
        {status = stat;}
    void setAge(int _age)
        {age = _age;}

    string getFirstName()
        {return firstname ;}
    string getLastName()
        {return lastname ;}
    string getCurrentTeam()
        {return currentteam ;}
    string getPosition()
        {return position ;}
    string getStatus()
        {return status ;}
    int getAge()
        {return age ;}
};

user player[20] ;

int main()
{
     ;

    int menu ;

    cout << "MENU" << "\n" ;
    cout << "\n 1. Store Player Information" ;
    cout << "\n 2. Show Player Informaton" ;
    cout << "\n 0. Exit" ;


    cin >> menu ;
    if (menu = 1)
    {
        storeinfo() ;
    }
    else if (menu = 2)
    {
        showinfo() ;
    }
    else if (menu = 0)
    {
        return 0;
    }


    cin.get() ;
    return 0 ;

}

void storeinfo()
{
    string firstname ;
    string lastname ;
    string currentteam ;
    string position;
    string status ;
    int age ;

    for (int i=0; i < 3; i++)
    {
        cout << "Enter First Name : " ; cin >> firstname ;
        player[i].setFirstName(firstname) ;
        cout << "Enter Last Name : " ; cin >> lastname ;
        player[i].setLastName(lastname) ;
        cout << "Enter Player's Age : " ;cin >> age;
        player[i].setAge(age) ;
        cout << "Enter Current Team : " ; cin >> currentteam ;
        player[i].setCurrentTeam(currentteam) ;
        cout << "Enter Position : " ; cin >> position ;
        player[i].setPosition(position) ;
        cout << "Enter Status : " ; cin >> status ;
        player[i].setStatus(status) ;
    }
}

void showinfo()
{
    for (int i=0; i < 3; i++)
    {
        cout << "First Name : " << player[i].getFirstName() << "        " << "Last Name : " << player[i].getLastName() <<
            "       " << "Age : " << player[i].getAge() << "        " << "Current Team : " << player[i].getCurrentTeam() << 
            "       " << "Position : " << player[i].getPosition() << "      " << "Status :  " << player[i].getStatus() ;
    }
}

感谢您的帮助。
