? with cin and cout

It seems that with all the programs I make I always end up dumping them because first time I test run the cin and cout dont work and I'm tried of it and want to know what I'm doing wrong. This is usaly how my intro is.

Code:

---

#include <isostream>
using::cin;
using::cout;

---

It's iostream, not isostream.

Also,

Code:

---

using std::cin;
using std::cout;

---

Right, I'm blind. I knew these lines looked odd to me, but I just didn't see just how odd.
