C++ 联系人文件程序

Question

我对我在 C++ Visual Studios 中创建的程序有疑问。首先我要做的是获取用户输入的所有关于帐户的信息，然后显示给用户以确保输入正确。然后将该信息放入文件 AccountInformation.txt。到目前为止，我已经完成了所有工作，它从做得很好 cin >> Street 然后它将把接下来的两个 cin 组合在一起，所以我不知道为什么要这样做。这是程序现在运行时的代码和示例输出。

// CreateWriteDisplay.cpp : This file contains the 'main' function. Program execution begins and ends there.
//
#include <fstream>
#include <iostream>
#include <string> 
#include <ostream>
using std::cout;     //using namespace std is not a good practice **
using std::cin;      //it's best to use std:: scope or using only what you need
using std::string;   //not the whole namespace, C++17 allows for comma
using std::endl;     //separated usings
using namespace std;
// Declares all the variables I need.
int AccountAge;
string LastName;
string FirstName;
string Ocupation;
string UserName;
string EmailAdd;

int main()

    char name[MAX_NAME_LENGTH], address[MAX_ADDRESS_LENGTH],
        about[MAX_ABOUT_LENGTH];
//Gets The Accounts Personal Information: Ocupation, Full Name, Age, Email, Home Address, Telephone Number, UserName, HomeDirectory, RoamingProfile,

 cin >> RoamingProfile; 
 }
 else {
     string RoamingProfile = "N / A";
 }
//getline(cin, HomeAddress);

// Displays All the information entered by the user To verify it was entered correctly.

Answer 1

您需要将 cin >> EmailAdd; 正下方的行更改为 cin.ignore(); 然后输入 getline(cin, HomeAddress); 将获取整个地址并将其全部存储在变量 HomeAddress 中，就像我想要的那样.我还实施了一些其他更改，以使其运行更流畅。
