i was reading a tutorial on random numbers: #include <windows.h> #include <iostream> using namespace std; I know what the first two lines refer to and do but what does the third line do? A comment says: "This is for the standard functionality of iostream" <----????? What about me? What about Raven?

When you use "iostream" instead of "iostream.h", you must put "using namesapce std" to avoid name conflicts.
