Miért nem működik ez a C++ program? (forráskód lent)

//

// Program to convert temperature from Clelsius degree

// units into Fahrenheit degree units:

// Fahrenheit = Celsius * (212 - 32)/100 + 32

//

#include <cstdio>

#include <cstdlib>

#incluse <iostream>

using namespace std;

int main (int nNnumberofArgs, char* pszArgs[])

{

// enter the temperature in Celsius

int celsius;

cout << "Enter the temperature in Celsius:" ;

cin >> celsius;

// calculate conversion factor for Celsius

// to Fahrenheit

int factor;

factor = 212 - 32;

// use conversition factor to concert Celsius

// into Fahrenheit values

int fahrenheit;

fahrenheit = factor * celsius/100 + 32;

//output the results (followed by a NewLine)

cout << "Fahrenheit value is:" ;

cout << fahrenheit << endl ;

// wait until user is ready before terminating program

// to allow the user to see the program results

system("PAUSE") ;

return 0 ;

}

Szépen begépelgettem a C++ for dummies könyvből ( [link] ), mivel onnan tanulok :D
