getline: identifier not found
提问by Adam Fatyga
I have problem with getline().
I tried many examples and read other solutions, but that didn't solve my problem. I still have info 'getline: identifier not found'.
I included
<stdio.h> <tchar.h> <iostream> <conio.h> <stdlib.h> <fstream>and still nothing.
我有问题getline()。
我尝试了很多示例并阅读了其他解决方案，但这并没有解决我的问题。我还有资料'getline: identifier not found'。我包括
<stdio.h> <tchar.h> <iostream> <conio.h> <stdlib.h> <fstream>但仍然没有。
#include "stdafx.h"
using namespace std;
int main(int argc, _TCHAR* argv[])
{
string line;
getline(cin, line);
cout << "You entered: " << line << endl;
}
What do I need to do now? I use Win7 64bit, MSVS2013.
我现在需要做什么？我使用的是 Win7 64 位，MSVS2013。

Get used to simply reading the documentationfor the language features that you use.
cppreference is quite clear that std::getlinemay found in string.
习惯于简单地阅读您使用的语言功能的文档。
cppreference 很清楚，std::getline可以在string.
#include <string>

This should fix that:
这应该解决这个问题：
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
int main(int argc, _TCHAR* argv[]){
string line;
getline(cin, line);
cout << "You entered: " << line << endl;
}

#include <string>
Incidentally, "Murach's C++ Programming" textbook incorrectly states that getline() is in the iostream header (p. 71) which may lead to some confusion.
顺便说一句，“Murach 的 C++ 编程”教科书错误地指出 getline() 位于 iostream 标头（第 71 页）中，这可能会导致一些混淆。
