How to include other Libs, very newbish question !

Hello everyone!!
i have a very easy question to ask! I havn't used any other libs in such along time i fogot how to even include them....

i always was using

#include <iostream.h>

then i tried to use vectors in a sorting program but i typed in

Code:

---

#include <iostream.h>
#incldue <vector.h>

---

still nothing worked....

then i used

#include <iostream>
#include <vector>

still it said File coudn't be found....

SO what do i have to use?

do i have to type in

#include <iostream.h>
#include <vector>
using namespace::std;

or is that how u even write it?
i am not use to using namespace std so can someone give me an example?

I'm currently running VC++6.0, i'm using console by the Way!!
:D

You should avoid using iostream.h. Instead use

Code:

---

#include <iostream>
#include <vector>
#include <string>

using namespace std;
...
