Unable to print the value of nullptr on screen

Question

I was reading about nullptr and doing workout on g++ and also on VS2010.

When I did

#include 
using namespace std;

aut         


        

Answer 1

The pointer literal is the keyword nullptr. It is a prvalue of type std::nullptr_t.

Type nullptr_t should be convertible to T*, but compiler has no operator << for nullptr_t and don't know to which type you want to convert nullptr.

You can use this

cout << static_cast(nullptr) << endl;
