Hi, John. Thanks very much for replying.
I am doing some php3/MySQL stuff here. php3 uses a lot of C language, so I
figured just learn the whole C language. Got the C++ book by Stephen Davis,
and tried to install the GNU C++ for Windows/NT. (as if the dad of three
pre-teens can crash-learn anything!)
As a function check, I tried to compile this simple code below, also taken
from the CD ROM included with the book. But it stumbles over the included
file iostream.h. The compiler finds errors in iostream.h.
Downloading/installing GNU C++ from the DJGPP website yields essentially the
same results - compiler goes on about how screwed up isotream.h is.
Compiling the code on a UNIX platform presents no problems, only Win/NT. I
suspect that somewhere in the code for iostream.h, maybe some characters
(seen or unseen) might be getting garbled, so I've included the first few
lines of the included file and the first few lines of compile errors below.
Being a serious beginner at C/C++, I don't understand what's wrong with
having an ampersand in a statement where it is, especially not in one of
these '.h ' files, etc.
As I page through the delorie web site, it seems that lots of folks are
having problems with this file. The only thing that I can think of is that
maybe I used the wrong version of unzip. Maybe if I use pkunzip versus
WinZip, it might be better. I followed the instructions twice, enabling the
right things, etc. But on the face of what I've got, I'm stumped now. We've
got some test engineers, and they use C/C++ for component test programs.
They are stumped, too.
The first part of the results are included below.
Thanks for your attention and time, Kevin O'Dwyer

"HELLO WORLD" EXAMPLE FILE:
==========================
//
// Conversion - convert temperature from Celsius
// degree units into Fahrenheit degree
// units:
// Fahrenheit = Celsius * (212 - 32)/100 + 32
//
#include <stdio.h>
#include <iostream.h>
int main(int nNumberofArgs, char* pszArgs[])
{
// enter the temperature in Celsius
int nCelsius;
cout << "Enter the temperature in Celsius:";
cin >> nCelsius;
// calculate conversion factor for Celsius
// to Fahrenheit
int nFactor;
nFactor = 212 - 32;
// use conversion factor to convert Celsius
// into Fahrenheit values
int nFahrenheit;
nFahrenheit = nFactor * nCelsius/100 + 32;
// output the results
cout << "Fahrenheit value is:";
cout << nFahrenheit;
return 0;
}
FIRST FEW LINES OF iostream.h:
=========================

#pragma interface
#endif

typedef ios& (*__manip)(ios&);

extern ostream& flush(ostream& outs);
extern ostream& endl(ostream& outs);
extern ostream& ends(ostream& outs);
etc, etc, etc.......
FIRST FEW LINES OF COMPILE ERRORS:
