问题描述

当我尝试创建一个对象时，我在 Visual Studio 中收到 LNK2001 错误，我认为这是构造函数的问题，因为更改构造函数会更改错误.

When I try to create an object I get a LNK2001 error in Visual Studio, it's a problem with the constructor I think since changing the constructor changes the error.

Customer bob("Bob", "25 Bob Lane", "01bob82", "M", "bob/bob/bob");

这一行给出了这个错误:

This line gives this error:

Error   1   error LNK2001: unresolved external symbol "public: __thiscall
Customer::Customer(class std::basic_string<char,struct std::char_traits<char>,class

包含构造函数的客户类:

Customer class that contains the constructor:

#pragma once
#include "l_list.h"
#include "Account.h"
#include <string>

using namespace std;

class Customer
{
private:
    l_list<Account> accounts;
    string name;
    string address;
    string telNo;
    string sex;
    string dob;

public:
    Customer(string name, string address, string telNo, string sex, string dob)
    {
        Customer::name = name;
        Customer::address = address;
        Customer::telNo = telNo;
        Customer::sex = sex;
        Customer::dob = dob;
    }

    void createAccount()
    {
        cout << "What type of account?";

    }

};
