./write_on_stderr

A binary that writes on standard error the first given argument (the same behavior as echo but with only one argument) and exits with an error status code given as second argument. If no argument is given, it writes the string "write on stderr" and exit with status 1.

	}
	else
	{
		write(2, "write on stderr\n", 16);

	if (argc == 3)
		return (atoi(argv[2]));
