How to create a directory in C++
提问by user1143336
i just found a little piece of code that let me create a directory with windows API without using system(). The only problem is that i can't create directory in subdirectory. For example
我刚刚找到了一小段代码，可以让我在不使用 system() 的情况下使用 Windows API 创建一个目录。唯一的问题是我无法在子目录中创建目录。例如
#include<windows.h>
int main(){
CreateDirectory ("C:\random", NULL);
return 0;
}
Create a folder named random in C.
在 C 中创建一个名为 random 的文件夹。
But if i do
但如果我这样做
#include<windows.h>
int main(){
CreateDirectory ("C:\Users\morons", NULL);
return 0;
}
It creates in C che folder named Usersmorons and not the folder morons under Users. Any suggest?
它在名为 Usersmorons 的 C che 文件夹中创建，而不是在用户下的文件夹 morons。有什么建议吗？

You will need admin access to create or delete a folder in C:\Users. Make sure that you are running the .exe as admin, to ensure you have these privileges. If you do not, then CreateDirectory will fail.
您将需要管理员访问权限才能在 C:\Users 中创建或删除文件夹。确保您以管理员身份运行 .exe，以确保您拥有这些权限。如果不这样做，则 CreateDirectory 将失败。
To get the error that is returned, use GetLastError. For a reference on the errors that may return, please take a look at the "Return value" section at
要获取返回的错误，请使用 GetLastError。有关可能返回的错误的参考，请查看“返回值”部分

Also, the code you are looking for is
此外，您正在寻找的代码是
CreateDirectory ("C:\Users\morons", NULL);
As there needs to be a "\\" before "morons"
因为在“白痴”之前需要一个“\\”

You need another backslash in there:
你需要另一个反斜杠：
CreateDirectory ("C:\Users\morons", NULL);

Making a windows application cross-platform, was using CreateDirectory()c++17 standard now has std::filesystem::create_directories
制作跨平台的 windows 应用程序，使用CreateDirectory()c++17 标准现在有std::filesystem::create_directories
#include<iostream>
#include <filesystem>
int main()
{
std::filesystem::create_directories("C:\newfolder\morons");
}
Needs changes in makefile to -std=c++17and updating to a GCC compiler that supports c++17.
需要更改生成文件-std=c++17并更新到支持 c++17 的 GCC 编译器。
