This is because all of the iostream functions are declared inside a 
namespace called std. Two possible fixes follow:

either put the following line here, this will expose every thing in 
namespace std, so you don't need to do it explicitly each time you use 
something within std:

using namespace std;

or substitute the following here instead, this explicitly uses cout from 
namespace std, and so you would need to do it each time you used cout, 
cin, endl... etc:

std::cout << "Hello World!\n";
