#
The pointer literal is the keyword nullptr.
It is a prvalue of type std​::​nullptr_­t.
[ Note
:
std​::​nullptr_­t is a distinct type that is neither a pointer type nor a pointer-to-member type; rather, a prvalue of this type is a null pointer constant and can be converted to a null pointer value or null member pointer value.
