I am just starting to learn C++ but can't seem to compile and run my first
program. I get the subject error at "cin > nCelsius " at line 9.  I am using
DJGPP in a RHID149 environment and followed all the instructions for setting
LFN=Y in DJGPP.ENV, SET DJGPP=C:\DJGPP\BIN in Autoexec.bat, FILES=55 in
config.sys (the only statement in config.sys).  I am running in a DOS Window
under Windows 98-2nd Ed. Rhide was run from "My Documents\Cplus" folder with
C:\DJGPP;C:\DJGPP\BIN in the PATH.

The file "iostream" was found in C:\DJGPP\lang\cxx-31. The file
"iostream.h", found in C:\DJGPP\cxx-31\backward gave error messages that
were eliminated when I used "iostream" in the #include statement.
I have read all the FAQs and still can't solve the problem. My installation
using Winzip unzipped all files into C:\DJGPP and its recursed
subdirectories using the following downloaded files:
    v2/djdev203.zip
    v2/faq230.zip
    v2/readme.1st
    v2/rhid149b.zip
    v2gnu/bnu213b.zip
    v2gnu/gcc31b.zip
    v2gnu/gpp31b.zip
    v2gnu/mak3791b.zip
    v2gnu/txi42b.zip

My program "conv.cpp" is as follows:

// C to F
include <stdio.h>
#include <iostream>
using std::cout;
using std::cin;
int main(int nNumberofArgs, char* pszArgs[])
{
  cout << "Input temperture in Celsius.\n";
  int nCelsius;
  cin > nCelsius;
  int nFahrenheit;
  nFahrenheit=9*nCelsius/5 + 32
  cout << "Temperature in Fahrenheit is ";
  cout << nFahrenheit
  return(0);
}

Anyone's help is appreciated.
