No, in C++, using nullptr is one way to get a null pointer. It is not,
however, the only way:

"A null pointer constant is an integral constant expression (5.19)
rvalue of integer type that evaluates to zero or an rvalue of type
std::nullptr_t. A null pointer constant can be converted to a pointer
type; the result is the null pointer value of that type..." (4.10p1).

Note that nullptr is an rvalue of type std::nullptr_t, but other things
can also have that type. Also, null pointers can be created by
conversion from null pointer constants, but they can also be generated
by other means.
