C++ Help

[JosefBud]

I got a C++ for dummies book and I have this code for it.. The program is on the CD it came with, but it was also in the book so I copied into my own. The one on the CD runs perfectly, but mine is poopy. I'm using Dev-C++. Here's the code:

//
// Program to 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 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;
}

and this is the log:

using namespace std;

you have to add aline before int main , "every time "
using namespace std;

if you want my advice try to use microsoft visual C++ , it is the best

Yes i tend to agree here
