ofstream不起作用 [英] ofstream doesn't work

问题描述

#include "stdafx.h"
#include <string>
#include <iostream>
#include <fstream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	ofstream myfile;
	myfile.open("C:\\example.txt", ofstream::out);
        //doesn't create the file and myfile.is_open() returns false
	myfile << "Writing this to a file.\n";
	myfile.close();
}

当你需要提出这类问题时，这有点令人沮丧。

在Windows控制台应用程序中，如果我提供无路径，则ofstream不会在给定位置创建任何文件，但是，确实如此。

无论我是否使用构造函数或open函数，仍然无法正常工作

It's kinda frustrating when you have the need to ask questions of this kind.
Here it is, on a windows console application, ofstream is not creating any file at the given location, if I supply no-path, however, it does.
No matter if I use the constructor or the open function, still doesn't work

推荐答案

您的应用程序可能没有写入主硬盘根文件夹的权限。

Possibly your application has not the privileges for writing on the root folder of the main hard disk.
