c++ - 错误:聚合类型不完整,无法定义
问题描述
我正在为银行编写程序,编译时出现此错误。这是我的全部代码,因为我无法在此处共享更多代码,它位于粘贴箱中。我的代码
我没有包括我的整个代码,而是我认为负责的部分:
#include<iostream>
#include<string>
#include<limits>
#include<fstream>
#include<iomanip>
using std::ios_base;
using std::ostringstream;
using std::ios;
using std::fstream;
using std::ifstream;
using std::ofstream;
using std::stoi;
using std::to_string;
using std::string;
using std::cout;
using std::cin;
using std::endl;
using std::getline;
class yourbankaccount
{
private:
string accountNumber;
// Name of the customer.
string name;
// Date of birth
int day;
int month;
int year;
// Get Age
int age;
// Get Gender
string gender;
long accountBalance = 0;
public:
friend int getInt(string info, int length);
friend string getStr(string info, int length);
yourbankaccount(){}
void setAccountNumber(string number){
accountNumber = number;
}
string shareAccountNumber(){
return accountNumber;
}
// Get date
void getDate(){
int d, m, y;
cout << "Now please enter your Date Of Birth(DD/MM/YYYY):"<<endl;
d = getInt("Day(DD)", 2);
m = getInt("Month(MM)", 2);
y = getInt("Year(YYYY)", 4);
day = d; month = m; year = y;
}
// Return Date
string sendDate(){
string Date = to_string(day) + "/" + to_string(month) + "/" + to_string(year);
return Date;
}
// Method to add details.
void getCustomerDetails(){
bool gotGen = false;
string n; int a; unsigned int p; char g;
cout << "Please fill in the following details: ";
name = getStr("Name of Account holder", 45);
cout << "Enter your birthday in given format: ";
getDate();
age = getInt("your Age", 2);
do
{
gender = getStr("your Gender(only M for Male, F for Female, O for Other)", 1);
if (stringToUpper(gender) != "M" ||
stringToUpper(gender) != "F" ||
stringToUpper(gender) != "O"){
"Please enter only M or F or O!";
}else{
gotGen = true;
}
} while (gotGen);
}
string shareName(){
return name;
}
string shareDOB(){
return sendDate();
}
int shareAge(){
return age;
}
string shareGender(){
return gender;
}
void setAccountBalance(long bal){
accountBalance = bal;
}
long shareAccountBalance(){
return accountBalance;
}
~yourbankaccount(){}
};
我在这里声明对象:
void createAccount(){
ofstream addAccount;
yourbankaccount Account;
cout << "Thank You for Choosing Your Bank.";
cout << "Please provide The folling details.";
Account.setAccountNumber(calNewAccNumber());
Account.getCustomerDetails();
Account.setAccountBalance(500);
int pin = getInt("a pin for the account", 4);
string file ="accounts/open.csv";
addAccount.open(file, ios::out | ios::app);
if (addAccount.is_open())
{
addAccount << Account.shareAccountNumber()
<< "," << pin << "," << "\"" << Account.shareName() << "\"" << ","
<< Account.shareDOB() <<"," << Account.shareAge()
<< "," << Account.shareGender() << Account.shareAccountBalance()<<"\n";
}
cout << "Your Account has been created Sucessfully." <<
"Please note your number as it will be required for logging in\n";
cout << "Account number is:" << Account.shareAccountNumber() << "\n";
}
编译时出现此错误:
