to the system function for deleting files (unlink, erase
or del).

#include <stdio.h>
main ()
{
if( remove( "myfile.txt" ) == -1 )
perror( "Error deleting file" );
else
puts( "File successfully deleted" );
return 0;
}
If the file example.txt existed before the execution and we
had write access to it the file will be deleted and this message will
be written to stdout:
File successfully deleted

Error deleting file: No such file or directory
