Simple hello world problem

[Kris Munch]

New to MacOSX, and just installed the Mac Developer suite so I could 
use gcc. However, when creating the simple hello world program, I 
cannot get it to compile:

#include <iostream>
#include <stdio.h>

int main()
{
         cout << "TESTING.." << endl;
         return 0;
}


I get these errors:
myprog.cc: In function `int main()':
myprog.cc:6: `cout' undeclared (first use this function)
myprog.cc:6: (Each undeclared identifier is reported only once for each
    function it appears in.)
myprog.cc:6: `endl' undeclared (first use this function)


Like it doesn't know where the includes are, an cannot figure out what 
cout is. Can anyone help?
