classes A and B. B has a private member int x and it should declare a friend function in the header for B to change A, however B's Header sould know A (inlude "a.h")and A's header should know B. but when i do so i get the error include nested level 363

I do I make a string member for a class.

i must use namespace std in order to make it work but then i get the familiar problem of using namespace in header file - I do I set the conflict)

 MSDN example:
// Declare and initialize variables
hostent* remoteHost;
char* host_name;
unsigned int addr;

//----------------------
// User inputs name of host
printf("Input name of host: ");
host_name = (char*) malloc(sizeof(char*)*16);
fgets(host_name, 16, stdin);

// If the user input is an alpha name for the host, use gethostbyname()
// If not, get host by addr (assume IPv4)
if (isalpha(host_name[0])) {   /* host address is a name */
  host_name[strlen(host_name)-1] = '\0'; /* NULL TERMINATED */
  remoteHost = gethostbyname(host_name);
}
else  { 
  addr = inet_addr(host_name);
  remoteHost = gethostbyaddr((char *) &addr, 4, AF_INET);
}

if (WSAGetLastError() != 0) {
  if (WSAGetLastError() == 11001)
  printf("Host not found...\nExiting.\n");
}
else
  printf("error#:%ld\n", WSAGetLastError());

// The remoteHost structure can now be used to
// access information about the host

What about justified or blocked style text for the multi line option?
