C++ Halp

So I've been coding C++ for a long time and I just got Visual C++ 2008 Express Edition.
The thing is everything I do including hello world seems to be 'out of date'.
So is it worth relearning because of this or should I just go with an older version?

Example of out of date. Does anyone know why?

#include <iostream>
using namespace std;
int main(){
cout << "Hello World!\n";
system("Pause");
}

system("Pause");
ONE WORD, THE FORCED UNPORTABILITY OF THE CODE, THREAD OVER
