Why file is not created in /etc/ directory

Please find the code sample

void createFile(const std::string& FileName, const std::string& Content)
ofstream of(FileName.c_str());
const std::string testFile = "/etc/testFile";
const std::string EmptyContent = "";
createFile(testFile, EmptyContent);

File is not creating at /etc/ directory. I think this is related to permissions. What extra I have to add in the code to work.


There's nothing extra that you can add to this program to "make it work". If an arbitrary program can write to /etc, this would toss the traditional POSIX security model out the window.

In order to be able to write to /etc, your program must be executed as root.
