c++ - ofstream 不会在文档文件夹中创建文件

Question

我正在尝试为我正在制作的游戏制作一个功能，将游戏中的数据保存到文件夹中的文本文件中，两者都具有用户提供的名称。我能够在我的项目文件夹中执行此操作，并希望它位于更通用的位置，所以我正在尝试文档文件夹。

但是，当我切换位置时，​​代码停止生成所需的结果，并开始在程序的主目录中创建文件和文件夹。 (文件不在文件夹内，仅供引用)

void Player::save()
{
system("mkdir \"C:\\Users\\Default\\Documents\\Ice Road\""); 
   //Make "Ice Road" folder in documents
std::string filename((name + ".txt")); 
   //make a name (inputed by the user earlier) to later be used to name a text file

std::string command("mkdir "); 
   //string to be combined with name to make folder
std::string commandString((command + name)); 
   //combine to make string command that creates folder
std::string newDir = ("C:\\Users\\Default\\Documents\\Ice Road\\" + name); 
   //string to set directory to newly created folder

std::ofstream saveStream;
   //open output stream for the saving process
SetCurrentDirectory("C:\\Users\\Default\\Documents\\Ice Road\\");
   //set the directory to the Ice Road documents folder (DOES NOT WORK)
system((commandString.c_str()));
   //create named folder for the save files.

SetCurrentDirectory(newDir.c_str());
   //set the directory to the newly created folder
saveStream.open(filename.c_str());
   //Create/open a text file that holds the data being saved
system("echo on");
   //turn on echo for debugging

saveStream << name << std::endl 
<< difficulty << std::endl 
<< health << std::endl 
<< warmth << std::endl 
<< hunger << std::endl 
<< packSpace << std::endl 
<< packUsed << std::endl;
saveStream.close();
   //input data to save file

system("dir");
   //show folder for debugging  
system("PAUSE");
   //wait for input
}

我如何获得此代码以在名为 Ice Road 的文档中创建一个文件夹，其中包含命名文件夹和命名文本文件？

(文档\冰路\你的名字\你的名字.txt)

我解决了这个问题。我最大的问题是我无法访问此文件夹 (UAC)，但因为我没有收到任何错误，所以我没有想到它。在那和其他一些调整之间，我让它工作如下所示，以管理员身份运行。

void Player::save()
{
std::string iceroad("C:\\Users\\Default\\Documents\\Ice Road");
    //Ice road directory, made into a string variable for easy usage, as recommended by Ben
system("mkdir \"C:\\Users\\Default\\Documents\\Ice Road\""); 
    //Make Ice Road folder in documents
std::string filename(iceroad + "\\" + name + "\\" + name + ".txt"); 
    //make a name (inputed by the user earlier) to later be used to name a text file, now using full address

std::string command("mkdir "); 
    //string to be combined with name to make folder
std::string commandString((command + name)); 
    //combine to make string command that creates folder
std::string newDir = (iceroad + "\\" + name); 
    //string to set directory to newly created folder, simplified

std::cout << filename;
    //debugging, as reccommended by Dietmar
std::ofstream saveStream;
    //open output stream for the saving process
SetCurrentDirectory(iceroad.c_str());
    //set the directory to the Ice Road documents folder
system("dir");
    //debugging, as recommended by Dietmar
system((commandString.c_str()));
    //create named folder for the save files.

SetCurrentDirectory(newDir.c_str());
    //set the directory to the newly created folder
saveStream.open(filename.c_str());
    //Create/open a text file that holds the data being saved
system("echo on");
    //turn on echo for debugging

saveStream << name << std::endl 
<< difficulty << std::endl 
<< health << std::endl 
<< warmth << std::endl 
<< hunger << std::endl 
<< packSpace << std::endl 
<< packUsed << std::endl;
saveStream.close();
    //inputs data to save file

system("dir");
    //show folder for debugging 
system("PAUSE");
    //wait for input
 }

感谢您的建设性批评，我确实将它们铭记在心并付诸实现。
