Visual C++ not allowing iostream

I just started C++ I am reading the ebook Starting out with C++ 7th edition. I copied the code from the book and put it into Visual, under new project w32 console app with precompiled headers. Well When I use the iostream in the preprocessor directive line i get.. I searched around and do not understand why the iostream won't work, any help?

1>------ Build started: Project: dd, Configuration: Debug Win32 ------
1>  stdafx.cpp 1>  dd.cpp 1>c:\documents and settings\leon\my documents\visual studio 2010\projects\dd\dd\dd.cpp(24): fatal error
C1010: unexpected end of file while looking for precompiled header.
Did you forget to add '#include "StdAfx.h"' to your source?
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

    1 // This program calculates the user's pay.
    2 #include <iostream>
    3 using namespace std;
    4
    5 int main()
    6 {
    7 double hours, rate, pay;
    8
    9 // Get the number of hours worked.
    10 cout << "How many hours did you work? ";
    11 cin >> hours;
    12
    13 // Get the hourly pay rate.
    14 cout << "How much do you get paid per hour? ";
    15 cin >> rate;
    16
    17 // Calculate the pay.
    18 pay = hours * rate;
    19
    20 // Display the pay.
    21 cout << "You have earned $" << pay << endl;
    22 return 0;
    23 }

Try this: 

#include "stdafx.h"
#include "iostream"

(remove .h extension - VS2010 seems to not find the header file with that file extension)?

When you create the new project, instead of selecting "w32 console app", select "Empty Project", then create a new CPP file, and the code should work!

Include the following header ..

#include "stdafx.h"

In Visual C++, project can use what is called "pre-compiled headers". This is a technique to help speed up building of the project. For this to work you need to #include the file "stdafx.h" as the first thing you do in the source file.

So add this line before the inclusion of iostream:

#include "stdafx.h"

When you build again it should work.

It's not because of iostream, but because you forgot to include stdafx.h.

The error is pretty clear on that. If you build projects with precompile headers, you have to include stdafx.h at the beginning of your implementation files.
