stl - Get vector of pointers from vector in C++ -

is there easy way of creating vector of pointers elements of vector?

i.e. easier below

std::vector<t*> fn(std::vector<t> &v) {   std::vector<t*> r;    (int = 0; < v.size(); i++)   {     r.push_back(&v[i]);   }    return r; } 

edit: incoming vector reference

as @benoit suggested, bad idea store these pointers. if really want it, can use std::transform this:

template<class t> struct address {     t* operator()(t& t) const     {         return &t;     } };   template<class t> vector<t*> fn(vector<t>&  v) {   vector<t*> r;   transform(v.begin(), v.end(), back_inserter(r), address<t>());   return r; }   int main( void ) {     vector<int> a;     a.push_back(0);     fn(a); }
