c++ - What exactly is nullptr? - Stack Overflow
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
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++?
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.
Better types in C++11 - nullptr, enum classes... - Cprogramming.com
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++ Tutorial: C++11/C++14 nullptr and strongly types enumerations...
nullptr. The constant 0 has had the double role of constant integer and null pointer constant. The ambiguity inherent in the double meaning of 0 was dealt with in C by the use of the preprocessor...
C++ - nullptr | c++ Tutorial
C++ nullptr. Example. C++11. Note that nullptr is not itself a pointer. The type of nullptr is a fundamental type known as std::nullptr_t.
nullptr in C++11 | 打字猴
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)。
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++
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.
C++11: nullptr - On C++ and other OOPscenities
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...
C++ 2011: nullptr
typedef decltype(nullptr) nullptr_t; The nullptr_t type It is possible to use 0 (NULL) and nullptr interchangeably (which is important for compatibility), like in the following examples
c++ - Custom nullptr_t class - Code Review Stack Exchange
I tried to write a nullptr_t class based on the official proposal to be used in C++03 only. The only differences with the proposal are that we can compare two nullptr_t instances and that it is...
(this == nullptr) // can this ever be true? : cpp_questions
According to the cpphints blog, (this == nullptr) [can no longer be true without preceding undefined...
