因为它试图对 int * 重新定义操作符 ++ 的含义。 References vs. const pointers C++ 中不允许定义”const reference”, 因为一个reference天生就是const。也就是说,一旦将一个reference绑定到一个对象,就无法再将它重新绑定到另一个不同的对象。在声 明一个reference之后没有写法可以将它重新绑定到另外一个对象。...

As you know, an address of an object in C++ can be stored either through a reference or through a pointer. Although it might appear that they represent similar concepts, one of the important differences is that you can reassign a pointer to point to a different address, but you cannot do...
First, as a general rule, prefer references over pointers. Even if you have to use pointers, as in references aren't an option, then something likestd::unique_ptrorstd::shared_ptrwould be better to use. Now, the most common use case for pointers / references are to prevent copies. Her...
the stack, and since the address is the same as the variable it references. More onstack vs heap. This implies that there is a real address of a reference that the compiler will not tell you. [c]int x = 0; int &r = x; int *p = &x; int *p2 = &r; assert(p == p2);[/...
A pointer cannot point to a reference or to astructthat contains references, because an object reference can be garbage collected even if a pointer is pointing to it. The garbage collector does not keep track of whether an object is being pointed to by any pointer types. ...

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...
