c++ - 未定义对 BankDetails::BankDetails() 的引用

Question

我不明白为什么我的 main.cpp 文件中出现以下错误： undefined reference to 'BankDetails::BankDetails()' undefined reference to 'BankDetails::Setname(std::string)' etc etc

我已经检查了所有内容，甚至在线查看了一些参考资料，但他们没有解释我哪里出错了。非常感谢您的帮助。

银行详细信息.h：

#ifndef BANKDETAILS_H
#define BANKDETAILS_H

#include <iostream>
#include <string>

using namespace std;

class BankDetails
{
    public:
        BankDetails();

        void Setaccnr(string accNr);
        void Settype(string accType);
        void Setbranch(string code);
        void SetinterestRate(double val);
        string Getname() const;
        string Getaccnr()const;
        string Gettype()const;
        string Getbranch()const;
        double GetinterestRate()const;

    private:

    //ctor

    accnr = accNr;
