Including iostream.h

I'm completly new to C++, downloaded it today, and have a problem: getting started. I tried a little tutorial first and copied this code:

Code:

---

// my first program in C++

#include <iostream.h>

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

---

in the Source Files > test.cpp window. Then I pressed F5 and got this error report:

Quote:

---

------ Build started: Project: Test, Configuration: Debug Win32 ------

As you see the problem is that iostream.h doesn't exist. How can I get it? Is it part of a compiler or something? I use Visual C++ 2005 Express Beta.

The latest C++ standard dictates that you remove the .h extension from all header files, and for files also standard in C, you precede the file name with 'c'. Then you, need to specify the name space you are using. There are several different ways of doing this, personally, I find the best method is to simply add the line, "using namespace std;" after my #include's. This should fix the problem - you'll find compilers will react different depending on when they were released.

Code:

---


#include <iostream>

using namespace std;

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

Thanks! It works... But the program closes immidately. What's the code for 'sleeping' or waiting for a key? And it starts in a command line window, how can you edit it so it's in a 'normal' window?

It's in the FAQ

Okay, I'll just check FAQ's before asking these questions from now on. :)

You are writing console based apps, thats why the console window (command line window) opens when you run your program. You aren't doing anything wrong here, thats what the majority of the sample programs are written in. It allows you to focus on learning the language without having to worry about the windows API.


I hope you have fun learning the language and feel free to post your questions so we can help you out along the way. Just mind
the forum guidelines

Happy Coding!!

To manage Windows programs, you'll need to learn the Windows API, or one of it's many wrappers. It's quite complicated and requires a pretty good knowledge of C/C++. Just keep learning the tutorials, and when you're done with those, check out Forger's Tutorial. It's one of the best I've seen - just google and you should find a copy.

Yeah, I heard about API. I'm just going to practise 'easy' things in C++, console based. When I know all the basic stuff I will switch to something harder. Another thing: I think I'll make this my 'standard forum' for asking C++ related questions. I like it here :).
