如何阅读包括空格在内的整行？ [英] How to read whole line including white space?

问题描述

我正在创建一个程序，要求用户输入一些信息，然后将其输入到文本文件中，但我无法弄清楚如何读取整行中的空格。当用户输入包含空格的行时，只有第一个单词出现在文本文件中。任何人都可以帮我解决这个问题吗？在此先感谢。


这是我的程序：

I am making a program that asks the user to enter some information and then enters it into a text file, but I can''t figure out how to read a whole line with spaces in it. When the user enters a line with spaces in it, only the first word appears in the text file. Can anyone help me figure this out? Thanks in advance.

这是我的计划：


#include< iostream>

#include< ; fstream>

#include< string>

使用命名空间std;


int main（）

{

string line;

ofstream myfile（" playlist.txt"）;

if（myfile.is_open（））

{

cout<< 输入艺术家：";

cin>> line;

myfile<< line<< endl;

cout<< 输入相册：;

cin>> line;

myfile<< line<< endl;

cout<< 输入曲目：;

cin>> line;

myfile<< line<< endl;

cout<< 输入歌曲：;

cin>> line;

myfile<< line<< endl;

cout<< 输入流派：";

cin>> line;

myfile<< line<< endl;

myfile.close（）;

}

else

cout<< 无法打开文件。;


返回0;

}




当我输入2pac for artist和Greatest Hits for album时，它跳过用户应该进入音轨的部分并转到歌曲，所以我输入了I Get Around的歌曲，它跳过了类型部分。


以下是它的作用：


输入艺术家：2pac

输入专辑：Greatest Hits

输入曲目：输入歌曲：我到处走走

输入流派：


这是输出它的文本文件：


2pac

I am making a program that asks the user to enter some information and then enters it into a text file, but I can''t figure out how to read a whole line with spaces in it. When the user enters a line with spaces in it, only the first word appears in the text file. Can anyone help me figure this out? Thanks in advance.

Here is my program:

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

int main ()
{
string line;
ofstream myfile("playlist.txt");
if(myfile.is_open())
{
cout << "Enter artist: ";
cin >> line;
myfile << line << endl;
cout << "Enter album: ";
cin >> line;
myfile << line << endl;
cout << "Enter track: ";
cin >> line;
myfile << line << endl;
cout << "Enter song: ";
cin >> line;
myfile << line << endl;
cout << "Enter genre: ";
cin >> line;
myfile << line << endl;
myfile.close();
}
else
cout << "Unable to open file.";

return 0;
}



When I enter 2pac for artist and Greatest Hits for album, it skips the part where the user is supposed to enter the track and goes to the song so I enter the song I Get Around, and it skips the genre part.

Here is what it does:

Enter artist: 2pac
Enter album: Greatest Hits
Enter track: Enter song: I Get Around
Enter genre:

Here is the text file it outputs it to:

2pac
Greatest
Hits
I
Get

Can somebody please help me?

你应该使用getline（）函数。从输入流中取整行：

You should use the getline() function. That takes a whole line from an input stream:

我也使用了这样的getline函数：

I''ve also used the getline function like this:
