Vectors and Multiple classes

[JMac89]

I have a vector of pointers to baseball players as indicated below

 vector<BaseballPlayer*> team;
         // stores information regarding a team

along with an iterator to traverse through the vector

vector<'NOT SURE WHAT TO DEFINE THIS AS'>::iterator Trav_Team;
         // iterator to traverse through a team

The purpose of this function is to store the different class objects into the vector which will later be used to print a player's information

void PlayerDatabase::load_team(ifstream &playerINPUT)
{
  Pitcher * ptrPitcher;
  Hitter  * ptrHitter;

  int pos;

  cout <<"Initializing team count = 0\n" << endl;


  char player_Position;
   // player's position on the team

  // while there is still input, continuing reading the file
  // and incrementing team count until EOF occurs
  while(playerINPUT >> player_Position)
   {
     /* check to see if the player is a pitcher or hitter */
         if(player_Position == 'P')
          {
                ptrPitcher = new Pitcher;
                ptrPitcher->load_player(playerINPUT);

                team.push_back(reinterpret_cast<BaseballPlayer*>(ptrPitcher));
                 //stores the Pitcher's information (object) into the team vector
          }
         else if(player_Position == 'H')
          {
                ptrHitter  = new Hitter;
                ptrHitter->load_player(playerINPUT);

                team.push_back(reinterpret_cast<BaseballPlayer*>(ptrHitter));
                 //stores the Hitter's information (object) into the team vector
          }

           team_count++;
            //increment total members on team and positioning

       cout <<"Loading member " << team_count << endl;
    }//end of while loop
}

When I create a routine to traverse through the team vector to print out the player information, if they are either a pitcher or hitter, it doesn't work, because the iterator is only of a certain type. How can I get the iterator access both the Pitcher and Hitter classes? Or if there is another method I'm not aware of.

If your Pitcher and Hitter classes are properly deriving from BaseballPlayer, it should work automatically. Furthermore, the reinterpret_cast should not be necessary.

vector<'NOT SURE WHAT TO DEFINE THIS AS'>::iterator Trav_Team;

In general the typename used to create the vector is the same that is used to create the iterator for that container type.

vector<int> values;
vector<int>::iterator iter;

vector<BasebalPlayer*> team;
vector<BasebalPlayer*>::iterator teamIter;

If you want more help you need to post more complete examples of what you are doing. Post a complete example preferrably as a single, compilable, unit with the three classes and a small main function that demonstrates the problem.
