c++ - Create a vector of pointers to abstract objects -

i'm sure there's better way this.

i'm trying create class hashtable given size @ instantiation, can't given size @ design time, can't use array internal representation of table, far know.

so here's i'm trying do:

#include <vector> #include <iostream> #include "nodes.h"  using namespace std;  template <class t> class hashtable{  protected:     vector<* tablenode<t>> mytable;     //other protected methods go here  public:     hashtable(int size){         mytable = vector<* tablenode<t>>(size,null);     }  //the rest of class }; 

from i've seen, vector best data structure use here, because let me give size in constructor, , lets me use mytable[index] style notation access contents. however, vs2010 doesn't use of vector<* tablenode<t>> , can't blame it. so, how create array or vector or whatever of pointers tablenode<t> elements?

move asterisk around:

vector<tablenode<t>*> mytable;  mytable = vector<tablenode<t>*>(size,null);
