I am having problem compiling my project

[datateknikk]

What is wrong here?
I get error on both "#include <iostream>" and "using namespace std;"

// This program calculates the user's pay.
#include <iostream>
using namespace std;
int main()
{
double hours, rate, pay;
// Get the number of hours worked.
cout << "Hvor mange arbeidstimer? ";
cin >> hours;
// Get the hourly pay rate.
cout << "Hva er timesbetalingen? ";
cin >> rate;
// Calculate MVA.
// cout << "Hva er MVA i prosenter";
// cin >> tax;
// Calculate the pay.
pay = hours * rate * 1.25;
// Display the pay.
cout << "Du har tjent KR: " << pay << endl;
return 0;
}

Someone that can rewrite this code for me?
And send to [e-mail]
