C++ getline只获取一部分信息

这是我的类，函数的定义和原型。。。。它们都在同一个main.cpp中 这是我的身体

class MovieData
{
private:
    string Title;
    string Director;
    int Year;
    int Time;

public:
    MovieData();
    void setTitle(string Title);
    void setDirector(string Director);
    void setYear(int Year);
    void setTime(int Time);
    string getTitle();
    string getDirector();
    int getYear();
    int getTime();
};

MovieData::MovieData()
{
    Title = "";
    Director = "";
    Year = 0;
    Time = 0;
}    

void MovieData::setTitle(string title)
{
    Title = title;
}    

void MovieData::setDirector(string director)
{
    Director = director;
}

void MovieData::setYear(int year)
{
    Year = year;
}

void MovieData::setTime(int time)
{
    Time = time;
}

string MovieData::getTitle()
{
    return Title;

    return Year;
}

int MovieData::getTime()

    return Time;
}

void readMovieData(MovieData *, int);
void MovieDatastats(MovieData *, int);

intmain（）
{
整数金额=0；
数量；
电影资料*pMovie；
pMovie=新电影数据[金额]；
cout在
cin>>amount；
之后，流中仍然有一个新行，因此当调用
getline（cin，title）
时，
title
将为空。然后使用默认参数调用
ignore（）
：streamsize n=1，int\u type delim=traits\u type:：eof（）

如果程序没有收到EOF，它将丢弃您输入的一个字符。您不需要在

getline（）之后调用
ignore（）
删除所有的
cin.ignore（）；
并添加这一行：
cin.ignore（一个大的数字，\n'）；
在
getline（cin，title）；
上面，它将工作。
您正在使用中断后系统（“暂停”）中断for循环
如果它不起作用，我会破坏它。如果它起作用，它将继续执行单个输入不会中断getline函数，在getline之后，您需要有一个cin.ignore（）来重置输入值。您需要通过调用
std:：cin.ignore（10000），\n'）；
在调用
getline（）之前忽略新行
。尝试调试，您会看到。谢谢！现在工作正常！您能解释一下cin。忽略（10000，“\n”）函数tho，这样我就可以学习=）看看这个
