What's wrong with this C++ program?

I'm simply trying to start learning C++, and this hello world thing isn't working. What's wrong with the code? This tutorial says I'm doing it right, but it keeps telling me line 5 is wrong.





#include %26lt;iostream.h%26gt;





int main()


{


cout %26lt;%26lt; "Hello World!\n";


return 0;


}

What's wrong with this C++ program?
Make the cout line the following:


std::cout %26lt;%26lt; "Hello World!" %26lt;%26lt; std::endl;
Reply:you forgot to add the line : using namespace std;


under the include directive


this lets the compiler know what cout means
Reply:If you are using Visual C++ compiler, then try


#include "iostream.h"
