     Thats one way. Here's another with explicit qualification:

#include <iostream>
int main()
{
  std::cout << "Hello, world!" << std::endl;
}

     Here's another with the compatibility header:

#include <iostream.h>
int main()
{
  cout << "Hello, world!" << endl;
}

     Here's another with using declarations:

#include <iostream>
using std::cout;
using std::endl;

int main()
{
  cout << "Hello, world!" << std::endl;
}

    Should continue to work. iostream.h looks basically like:

// file: iostream.h
#include <iostream>
using std::cout;
using std::endl;
using std:istream;
...... (all names are 'used')
