Question

From this code:

int x = 5;
int other = 10;
vector<int*> v_ptr; 
v_ptr.push_back(&x);
v_ptr.push_back(&other);
v_ptr.push_back(&x);

Is there anyway I can know who points at x, from the x variable itself, so that I don’t have to search inside v_ptr for address of x? Is this possible in C++ or C++0x?

I read that when doing garbage collection, they look at memory and see if anything points at it or not, then make decisions to delete the unused variable, etc.

No. It is like asking a person if they know everyone who knows their address.
