This can be done at the file/folder level of the File System. Assuming you are using Windows, this would be done with NTFS. C/C++ isn't ideal for protection of files. In my opinion that's the responsibility of the File System, not a programming language.

This can be achieved with file permissions, which as no2pencil said, is not a programming language's responsibility.
There is another approach I can think of, which depends on the type of file. You can use encryption for this file, and make it only readable by your Own program (which can also write/edit that file). This way you can avoid the copy problem.
