[Dev-C++] newbie problems

[Dario G. <gr...@bi...>]

hi to all.
i'm a newbie of c++.
i ve installed dev-c on a win 2000 pro system.
i wrote a simple program as "hello world" as this:

#include <iostream>
using namespace std;
int main ()
{
cout << "hello world";
return 0;
}

but when i compile this program, dev-c gives me 2 errors:
1) iostream is no such file or directory;
2) cout undeclared in first use.

i've tried to use the old standard:

#include <iostream.h>
...etc...

but the result is the same.

which is the problem?
the same response is gived using gcc under linux red hat 7.3.
thankyou for help.
