Maybe this should have been posted to ...learn.c-c++, but here we go.

I'm trying to learn c++ and tried to obtain" c++ primer plus:teach yourself..."
(S.Prata). It's not going to be reprinted, so I thought I'd check out
"Thinking in c++" 2ed by Bruce Eckel (it's free at www.bruceeckel.com), but
the exampels seem to be completely incompatible with DJGPP.
Am I doing something wrong or is this correct?
An example is:

//: C18:Stype.cpp
// Type a file to standard output
#include <fstream>
#include <iostream>
#include "../require.h"
using namespace std;

int main(int argc, char* argv[]) {
  requireArgs(argc,  2); // Must have a command line
  ifstream in(argv[1]);
  assure(in, argv[1]); // Ensure file exists
  cout << in.rdbuf(); // Outputs entire file
} ///:~

Quest.: #include "../require.h"
	declare _and_ open 'in' at once
	assure
	rdbuf
???

Hope you can help me
Regards

Lasse
