大家都知道,标准容器中是“按值”存放并操纵存放于其中的实例的,不允许在标准容器中存放“引用” 。 vector<int&> a; 编译过后,会出现一大堆的错误,但是我们可以很容易找到“pointer to reference is illegal”之类 的字眼儿,即“指向引用的指针”是非法的:因为容器中很可能有“T* t”之类的底层存储指针,那么...
REFERENCE_BY_POINTER 参数 参数说明 1 正在降低其引用计数的对象的对象类型。 2 正在降低其引用计数的对象。 3 预留 4 预留 原因 对象的引用计数对于对象的当前状态是非法的。 每当驱动程序使用指向对象的指针时,驱动程序都会调用内核例程,以将对象的引用计数加一。 使用指针完成驱动程序后,驱动程序将调用另一个内核...
Until when C++ comes along, then we have a new "reference" : int a = 10; int i =& a; // or int i = &a; i am not sure about the syntax. i = 20; // now both a and i are 20 so this type of reference is an implicit pointer... it points to a, but you don't use...

it is possible to create a pointer to a pointer, but not a pointer to a reference or reference to reference(will collapse). it is possible to create an array of pointers, but not an array of references. pointer can be assignednullptr, whereas a reference must be bound to an existing ob...

c) there is no such thing as a null reference (at least not in the sense a pointer can be null). Creating or accesing a reference implies a valid target. That too is guarenteed. int& r; // illegal int n; int& r_n = n; ... r_n = 4; // modifies n transparently since r_...
