问题描述

I'm out of practice with C++ and am writing a "Bank" class for a course I'm taking. 我没有使用C ++练习，正在为我正在学习的课程写一个“银行”课程。 I'm getting a long error every time I attempt to compile my Bank.cpp file. 每当我尝试编译Bank.cpp文件时，我都会收到很长的错误。 I suspect I'm missing something quite obvious here, but I don't know what because the error doesn't make any sense to me. 我怀疑我在这里遗漏了一些非常明显的东西，但我不知道是什么，因为错误对我没有任何意义。

Here's the cpp file I'm writing that won't compile: 这是我正在编写的无法编译的cpp文件： 

#include <iostream>

#include "Bank.h"

Bank::Bank(): savings(0), checking(0) { }

Bank::Bank(double savings_amount, double checking_amount): savings(savings_amount), checking(checking_amount) { }

void Bank::deposit(double amount, string account)
{
        if (account == "S") {
                savings = savings + amount;
        } else {
                checking += amount;
        }
}

void Bank::withdraw(double amount, string account)
{
        if (account == "S") {
                savings -= amount;
        } else {
                checking -= amount;
        }
}

void Bank::transfer(double amount, string account)
{
        if (account == "S") {
                savings -= amount;
                checking += amount;
        } else {
            checking -= amount;
        }
}

void Bank::transfer(double amount, string account)
{
        if (account == "S") {
                savings -= amount;
                checking += amount;
        } else {
                checking -= amount;
                savings += amount;
        }
}

void Bank::print_balances()
{
        cout << "Savings: $ " << savings;
        cout << "Checking: $ " << checking;
}

Here's the header file: 这是头文件： 

#ifndef BANK_H
#define BANK_H

#include <string>

#include "Account.h"

using namespace std;

class Bank {
private:
    Account savings;
    Account checking;
public:
    Bank();
    Bank(double savings_amount, double checking_amount);
    void deposit(double amount, string account);
    void withdraw(double amount, string account);
    void transfer(double amount, string account);
    void print_balances();
};

#endif

And here's the "Account.h" header file that is referenced at the top: 这里是顶部引用的“Account.h”头文件： 

#ifndef ACCOUNT_H
#define ACCOUNT_H


class Account {
private:
    double balance;
    double interest_rate;
public:
    Account();
    Account(double amount, double rate);
    void deposit(double);
    bool withdraw(double);
    double query();
    void set_interest_rate(double rate);
    double get_interest_rate();
    void add_interest();
};

#endif

And here is the cryptic error I'm receiving: 这是我收到的神秘错误：

Anyone know what I'm doing wrong? 谁知道我做错了什么？ I'm sure it's something pretty stupid. 我确定这是非常愚蠢的事情。 I can post the header file as well, but it's difficult to do so due to remote editing issues. 我也可以发布头文件，但由于远程编辑问题，很难这样做。

If you don't want to add extra operators to your classes, then instead of writing: 如果您不想在类中添加额外的运算符，那么请不要写： 

savings = savings + amount;

use the already declared methods of the Account class and write: 使用已经声明的Account类的方法并写： 

savings.deposit(amount);

You need to define the + operator for the Account class so it knows what to do. 您需要为Account类定义+运算符，以便它知道该怎么做。 Since you were trying to add an Account object with a double, you would need this. 由于您尝试使用double添加Account对象，因此您需要这样做。 

double Account::operator+(const double value) const {
    return balance + value;
}

If you want to add two account objects, you can overload with this. 如果要添加两个帐户对象，可以使用此方法重载。 

Account Account::operator+(const Account &other) const {
    return Account(balance + other.balance, interest_rate);
}

I suspect you declare saving and checking private members as "Account" rather than double. 我怀疑你宣布保存和检查私人成员为“帐户”而不是加倍。 Even if that is your intended design, you can not add user defined class objects without expliclity define operator+(const Account &). 即使这是您的预期设计，也无法在没有明确定义operator +（const Account＆）的情况下添加用户定义的类对象。

In this line of your source code: 在这行源代码中： 

            savings = savings + amount;

savings has a type of Account , but amount is a double . savings有一种Account ，但amount是double 。 Unless you define a + member operator on the Account class like 除非你在Account类上定义一个+成员运算符 

Account operator+(const double value) const;

Or a global + operator(possible as a friend function) like 或者像全局+运算符（可能作为friend函数） 

Account operator+(const Account& account, const double value);

Then you cannot do such addition. 那么你不能做这样的补充。
