function
<cstdio>

remove

int remove ( const char * filename );
Remove file
Deletes the file whose name is specified in filename.

This is an operation performed directly on a file identified by its filename; No streams are involved in the operation.

Proper file access shall be available.

Parameters

filename
C string containing the name of the file to be deleted.
Its value shall follow the file name specifications of the running environment and can include a path (if supported by the system).

Return value

If the file is successfully deleted, a zero value is returned.
On failure, a nonzero value is returned.
On most library implementations, the errno variable is also set to a system-specific error code on failure.

/* remove example: remove myfile.txt */
#include <stdio.h>

int main ()
{
  if( remove( "myfile.txt" ) != 0 )
    perror( "Error deleting file" );
  else
    puts( "File successfully deleted" );
  return 0;
}


If the file myfile.txt exists before the execution and the program has write access to it, the file would be deleted and this message would be written to stdout:
File successfully deleted

Otherwise, a message similar to this would be written to stderr:
Error deleting file: No such file or directory
