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;
}
