[QUOTE=galmca]i have tried everything[/QUOTE]But you forgot to copy and paste these attempts that we may correct them and instead assume that someone will drop in your lap exactly the code you are thinking of.

Neither. An array of [FONT=Courier New]char[/FONT] that ends with a terminating null byte is a c-style string. A single char thus can never be a string. And an uninitialized [FONT=Courier New]char data[];[/FONT] is an incomplete type. And [FONT=Courier New]'operator<<' not implemented in type 'istream' for arguments of type 'char *'[/FONT].

From a quick glance, I'd guess it might be related to the missing breaks for each case. Would you mind describing the error?

It prevents multiple inclusion of the header. That is, on a second attempt to [FONT=Courier New]#include "add.h"[/FONT], [FONT=Courier New]ADD_H[/FONT] would already be defined and thus the entire [FONT=Courier New]#ifndef[/FONT] block would be skipped.
