C++ in linux?

This may sound as an completely stupid question. But I'm really confused.

I want to program in C++ for Linux. I'm using Eclipse now, and I installed the C/C++ Development Tools.

I wanted to compile something really simple:

Code:

---

#include <iostream>
using namespace std;

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

return 0;
}

---

What should I do to get this to work?

I think most Linux distros include the g++ compiler (my Ubuntu has it) already installed. Find a good text editor (I use SCiTE) and compile it with g++

Ah, it works now.
Thank you!
