problem with .h files in include

[flamewavetech]

im a C/C++ begginer just startin out. i got a book with some stuff and it says i need the following .h files

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/time.h>
#include <sys/socket.h>
#include <netdb.h>
#include <netinet/in.h>
#include <netinet/ip.h>
#include <netinet/ip_icmp.h>

but my compiler says there "not found". anyone know whats goin on?

id also appreciate some tutorials on how to use the internet with C++

I think all files that are in a subdirectory are linux specific.

How to use the internet depends on the OS. In windows, there is the winsock API.
Internet is definitely an advanced topic.
