C ++：struct

Question

我是C ++的初学者，刚开始学习struct。 我创建结构并从文件中读取数据。

这是我的档案：

John Smith 26832904 1657 Commerce st Flushing NY 11204 7183942833 company01 962 51

我成功地将数据输入到结构中。输出很完美，但最后只有零，这可能让我发疯。

这是我的全部代码：

#include<iostream>
#include<string>
#include<fstream>
#include<iomanip>
using namespace std;

struct nametype
{
    string first;
    string last;
};

struct addresstype
{
    string address1;
    string address2;
    string address3;
    string city;
    string state;
    string zip;
};

struct contacttype
{
    string home;
    string person;
};

struct employeeType
{
    nametype name;
    string id;
    addresstype address;
    contacttype contact;
    string worklocate;
    double basewage;
    int carsale;
};

int main()
{
    ifstream infile;
    infile.open("employeeInfor.txt");
    if (!infile)
    {
        cout << "Error." << "\n";
    }

    employeeType employee;
    employee.basewage = 0.0;
    employee.carsale = 0;

    infile >> employee.name.first >> employee.name.last
        >> employee.id
        >> employee.address.address1 >> employee.address.address2
        >> employee.address.address3 >> employee.address.city
        >> employee.address.state >> employee.address.zip
        >> employee.contact.home >> employee.contact.person
        >> employee.worklocate
        >> employee.basewage >> employee.carsale;
    cout << employee.name.first <<" "<<employee.name.last
        << " " << employee.id
        << " " << employee.address.address1 << " " << employee.address.address2
        << " " << employee.address.address3 << " " << employee.address.city
        << " " << employee.address.state << " " << employee.address.zip
        << " " << employee.contact.home << " " << employee.contact.person
        << " " << employee.worklocate
        << " " << employee.basewage << " " << employee.carsale << "\n";


    infile.close();
    system("pause");
    return 0;
}

我输出数据。这就是我得到的：

The end of the extra 0 is not my expectation.

顺便说一下。我想把结构放在数组中。使此功能适用于多个员工。我知道应该创建类似employeeType员工的结构[5]; 我只是停止阅读文件。无法继续前进。

Answer 1

您尝试读取14个值，但输入文件仅包含13.因此，您输出的最后一个值employee.carsale与初始化中的0一样。

Answer 2

您阅读了14个参数，但您的文件仅提供了13.可能您忘记在employeeInfor.txt中添加列。
