It should be the correct one, because b and &b return different values

@Tobias B. you can save &b to another one by using void* c=&b. means that its a raw pointer that point to pointer. also you can use int **c = &b. pointer to pointer.

#include <iostream> using namespace std; int a; int *b = &a; int main() { cout << b << endl; //pointer cout << &b; //points to pointer return 0; } But I dont know how to save &b to a variable.

Thank you, I told of this way, but I wasn't sure if it's the correct one. In C++11 there is "std::addressof(ptr)", which, I think, does the thing.
