Program Won't Compile

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

Code:

---

//
// 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;

        // wait until user is ready before terminating program
        // to allow the user to see the program results
    system("PAUSE");
    return 0;
}

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

Code:

---

  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.
