c++ - What exactly is nullptr? - Stack Overflow
https://stackoverflow.com/questions/1282295/what-exactly-is-nullptr
int* x = nullptr; myclass* obj = nullptr; Still, I am not getting how nullptr works. C++11 corrects this by introducing a new keyword to serve as a distinguished null pointer constant: nullptr.
nullptr_t - C++ Reference
https://www.cplusplus.com/reference/cstddef/nullptr_t
Even though nullptr_t it is not a keyword, it identifies a distinct fundamental type: the type of nullptr. As such, it participates in overload resolution as a different type. This type is only defined for C++ (since...
What exactly is nullptr in C++?
https://www.tutorialspoint.com/what-exactly-is-nullptr-in-cplusplus
The nullptr denotes the pointer literals. It is a prvalue of type std::nullptr_t. It has implicit conversion property from nullptr to null pointer value of any pointer type and any pointer to member type.

nullptr, by the way, is not only declared to be a pointer and convert implicitly to all pointer types (and Regardless of all this--the rule of thumb for C++11 is simply to start using nullptr whenever you would...
Migrating from C to C++: NULL vs nullptr - Embedded Artistry

nullptr is a new keyword introduced in C++11. nullptr is meant as a replacement to NULL. nullptr provides a typesafe pointer Because of this ambiguity, I recommend switching exclusively to nullptr.
The Null Pointer Constant nullptr - ModernesCpp.com

The nullptr can be used to initialize a pointer of type long int (line 18). You can observe that in the lines 22 - 25. If the nullptr has to decide between a long int and a pointer, it will decide for a pointer...

C++11引進的nullptr是用來代表null pointer的值,它用來和integer 0做區隔。 原因是‧在於C++03/C99裡,NULL是由integer 0來做的(#define成0的macro)。
Null pointers

nullptr is an explicit null pointer constant. In C++, initializing null pointers with 0 or NULL have the following problems: It is impossible to distinguish between a null pointer and integer 0 for overloaded...
6.7a — Null pointers | Learn C++
https://www.learncpp.com/cpp-tutorial/6-7a-null-pointers/
C++ will implicitly convert nullptr to any pointer type. So in the above example, nullptr is implicitly converted to an integer pointer, and then the value of nullptr assigned to ptr.

Because it cannot decide if NULL is actually a pointer (because it is a 0) or an integer (because NULL is… a 0). C++11 introduces nullptr; a keyword that unambiguously represents a pointer pointing to...
