How do i rename or remove a file?

Also to add, std::rename and std::remove are throwing compile errors
saying rename and remove are not members of std, even after including
<cstdio> library.

Show us the code.

These function's take arguments that are filenames and have type
char const *, they don't have anything to do with fstream's or

First close any open fstream's you have associated with the file,
then call

std::rename( "oldname", "newname" ); or
std::remove( "oldname" );

Replace "oldname"/"newname" with the appropriate literals or
char const *varaible, or use std::string's c_str() member:

std::string name = "filename";

std::ifstream ifs( name.c_str() );

// read something from ifs;

ifs.close();

std::remove( name.c_str() );

How are you calling them, whats the error and what compiler are you
using. Prefereably post some actual code (cut & paste) that doesn't
compile.

HTH.
