Re: templated deletePointer in for_each algorithm

I'm afraid these are raw pointers, I have no option to use a smart
pointer. After some messing around, I arrived to the following code
which gets rid of my adapter. In the code, I do at least know when I
have a vector or a map, so I can use the separate functions
"deleteMapPointer" and "deleteVecPointer". It would, of course, be nicer
to overload a single "deletePointer" function. But someone a lot smarter
than me will have to work that out...

#include <iostream>
#include <string>
#include <vector>
#include <map>
#include <utility>
#include <algorithm>

template <class T>
void deletePointer(T* &myPointer){
   delete myPointer;
   myPointer = NULL;
}

template <class T>
void deleteMapPointer(typename T::value_type &myPair){
   delete myPair.second;
   myPair.second = NULL;
}

template <class T>
void deleteVecPointer(typename T::value_type &myVal){
   delete myVal;
   myVal = NULL;
}

using namespace std;
void print (string * elem){
   cout<<*elem<<" ";
}

void printPointer(string * p){
   cout<<hex<<p<<" ";
}

int main (int argc, char * const argv[]) {
   string * pMyString = new string;
   *pMyString = "hello";
   cout << "Heres the newed string :"<<*pMyString<<endl;
   cout << "with pointer value :"<<hex<<pMyString<<endl;
   //Deletion with resetting the pointer:
   deletePointer(pMyString);
   //
   cout << "The string has been deleted, and now.."<<endl;
   cout << "the pointer value is :"<<hex<<pMyString<<endl;
   //set up map and vector
   typedef map<int, string*> MapType;
   MapType myMap;
   typedef vector<string *> VecType;
   VecType myVec;
   typedef string * PString;
   for (int i(0);i not_eq 10; ++i){
      PString pString=new string;
      PString pString2=new string;
      *pString = "burt";
      *pString2 = "smith";
      myVec.push_back(pString);
      myMap.insert(make_pair(i,pString2));
   }
   for_each(myVec.begin(),myVec.end(),print);
   cout<<endl;
   for_each(myVec.begin(),myVec.end(),printPointer);
   cout<<endl;
   for_each(myVec.begin(),myVec.end(),deleteVecPointer<VecType>);
   for_each(myVec.begin(),myVec.end(),printPointer);
   cout<<endl;
  for_each(myMap.begin(),myMap.end(),deleteMapPointer<MapType>);
   cout<<hex<<myMap[2]<<endl;
   string myFalse("burt");
    return 0;
}
