stupid g++ question

The subject says it all. 
#include <iostream.h>
#include <string>
using namespace std;
int main()
        string s;
        s = "Hello, world!";
        cout << s << "\n";
There are better ways of doing this, but the addition of using namespace std; solves the problem. 
Apparently, Red Hat 7.2 (gcc 2.96) solves this either as a compiler default or by altering the 
header files. 
Of course, I could have opened by eyes when I looked at the string header file, (actially, 
bits/basic_string.h, where string is actually defined within namespace std. 
It's been about 4 years since I have done any profesisonal C++ coding.  Jerry Feldman
