问题在接受C++中的字符串的空格

Question

我写了这个代码来获取名称。电话和一个人的地址，然后我输入到这些类对象变量：

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

class contact{ 
public: 
    string name;//ALL CLASS VARIABLES ARE PUBLIC 
    unsigned int phonenumber; 
    string address; 

    contact(){//Constructor 
     name= "Noname"; 
     phonenumber= 0; 
     address= "Noaddress"; 
    } 

    /*void input_contact_name(string s){//function to take contact name 
     name=s; 
    } 
    void input_contact_number(int x){//function to take contact number 
     phonenumber=x; 
    } 
    void input_contact_address(string add){//function to take contact address 
     address=add; 
    }*/ 
}; 

int main(){ 
    contact *d; 
    d= new contact[200]; 
    string name,add; 
    int choice;//Variable for switch statement 
    unsigned int phno; 
    static int i=0;//i is declared as a static int variable 
    bool flag=false; 
    cout<<"\tWelcome to the phone Directory\n";//Welcome Message 
    cout<<"Select :\n1.Add New Contact\n2.Update Existing Contact\n3.Delete an Existing Entry\n4.Display All Contacts\n5.Search for a contact\n6.Exit PhoneBook\n\n\n";//Display all options 
    cin>>choice;//Input Choice from user 
    while(!flag){//While Loop Starts 
     switch(choice){//Switch Loop Starts 
     case 1: 
      cout<<"\nEnter The Name\n"; 
      cin>>name; 

      d[i].name=name; 
      cout<<"\nEnter the Phone Number\n"; 
      cin>>phno; 
      d[i].phonenumber=phno; 
      cout<<"\nEnter the address\n"; 
      cin>>add; 
      d[i].address=add; 
      i++; 

      flag=true; 
     } 
    } 
    return 0; 
} 

但是如果我进入其姓分离的名称，代码绕过下一CINS并退出。有人能帮我解释为什么会发生这种情况吗？ 当我输入10位数字单元号时，会发生同样的情况。 在此先感谢

使用std::getline()而不是operator>>来提取包含空格的std::string。
