Question

C++ 读文件 getline

#include "stdafx.h"
#include "iostream"
#include "fstream"

#include "string.h"
using namespace std;

void main(){
ifstream ifs("input.txt");
ofstream ofs("output.txt");
string temp;
int tempr,tempt;
while(!ifs.eof()){
getline(ifs,temp);
cout<<temp<<endl;
cin.get();
错误是
error C3861: “getline”: 找不到标识符
error C2679: 二进制“<<”: 没有找到接受“std::string”类型的右操作数的运算符(或没有可接受的转换)

Answer 1

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

void main()
{
ifstream ifs("input.txt");
ofstream ofs("output.txt");
string temp;
int tempr,tempt;
while(!ifs.eof())
{
getline(ifs,temp);
cout<<temp<<endl;
}
cin.get();
}

Answer 2

#include "stdafx.h"
#include "iostream"
#include "fstream"文件包含错误
#include "stdafx.h"
#include "iostream.h"
#include "fstream.h"
或
#include <stdafx>
#include <iostream>
#include <fstream>
