c++11 - how to maintain a pointer pointing to elements of vector? - 


 vector<int>vec(n,0);  int* ptr=vec;

can vector arrays or have have iterators.what want maintain pointer pointing elements of array.

i can think of couple of ways pointer elements of vector.

int* p = &(vec[0]);

or

int* p = vec.data();

however, unless know doing, don't recommend using pointers access elements of vector. use iterators access elements of vector. there not gained , lose preferring use pointers on iterators.
