C++ Question.

So I am starting with C++ and I am reading some books, I just started with the Hello World programs, so I want to make sure this is correct.

#include <iostream.h> //Tells the compiler that there will be a cout or cin.


main()
{
cout << "Hello World!";
return 0;
}

I would very much like all the feedback I can get, for I want to learn as much as I can.

 

That code doesn't work, try changing first line to:

Code:

#include <iostream> //Tells the compiler that there will be a cout or cin.
using namespace std;

Full code:

Code:

#include <iostream>
using namespace std;
 
main () {
  cout << "Hello World!";
  return 0;
}
