If you include <iostream>, then cout, cin and the like are declared inside the 'std' namespace. So the right way ( using that header, which is the standard ) could be:

#include <iostream>

using std::cout;
using std::endl;


int main( int argc, char** argv )
{
	cout << "Hi" << endl;

	return 0;
}

or better, IMHO

#include <iostream>

int main( int argc, char** argv )
{
	std::cout << "Hi" << std::endl;

}

Miguel.
