问题
I need help creating a Folder in AppData.
Lets say I want to create a Folder in %appdata% called "MyFolder", which has the text file test.txt
I tried to use <fstream> and do this;
ofstream file("%appdata%\MyFolder\test.txt");
but it didn't work..
回答1:
Things like %appdata% are OS specific, and Standard C++ has no direct means of dealing with them. You will have to write code to parse the file path, and extract values like %appdata% from the environment, or alternatively use non-standard functions to open the file, should such exist.
