Program Won't Compile

[Stumped]

Not sure why this won't compile. It says error on line 2

//
// program to convert temperature from Celcius degree
// units into Farenheit degree units:
// Fahrenheit = Celsius * (212 - 32)/100 + 32
//
   #include <cstdio>
   #include <cstdlib>
   #include <iostream>
   using namespace std:
    
   int main(int nNumberofArgs, 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 conversion factor to convert Celsius
   // into Fehrenheit values
       int fahrenheit;
       fahrenheit = factor * celsius/100 + 32;

        // output the results (followed by a NewLine)
    cout << "Fahrenheit value is:";
    cout << fahrenheit << endl;

        // to allow the user to see the program results
    system("PAUSE");
    return 0;

This is a joke isn't it ? ( my count is 9 )

   using namespace std;

Not a joke. Why. I don't know what I'm doing. It was what I was told to enter.

If you put a semicolon after "using namespace std" the program compiles and runs ok. If your compiler tells you that this is line 2 throw it away.
