It does not even compile. What did you want to rename?

Solution 1

First of all tell us what your problem is, do not leave it to us to figure out.

You're missing a missing a comma (,) before myfile.txt and you need to enclose myfile.txt in double apostrophes (")

Sure, but it might not work, as it also needs path, most likely the same as the source file, so the same "append" needed.
When a file is without path it will be created in working directory, and this directory totally depends on how the user runs the application.
(Good for simple applications, especially command line based.)

Yeah I'm aware of that, and I expected that the OP were too

Solution 2

It won't compile. Must be int rename ( const char * oldname, const char * newname );, http://www.cplusplus.com/reference/clibrary/cstdio/rename/[^]. Calculate two file names separately and pass to the function.
