有没有办法为指针的几个派生类有效地制作模板 function？

Question

#include <iostream>
#include <string>
#include <typeinfo>
#include <vector>
//Bird, bug, Fish, and lion are all derived from Animal.h
#include "Bird.h"
#include "Bug.h"
#include "Fish.h"
#include "Lion.h"
#include "animal.h"

//Main problem here
template <typename T>
void interact(T* classname) {
  cout << "Do you want to spank the animal or order it to "
          "do unique action? Type \"Spank\" if you want to spank it or type "
          "\"unique\" if you want "
          "it to do something unique."
       << endl;
  string action;
  std::cin >> action;
  for (int i = 0; i < action.size(); i++) {
    action[i] = toupper(action[i]);
  }
  if (action == "UNIQUE")
    cout << classname->unique() << endl;

  else if (action == "SPANK")
    cout << classname->makeNoise() << endl;

  else {
    cout << "You typed wrong";
  }
}


int main() {
  // Make a zoo.
  std::vector<Animal *> zoo;

  // Explanation to the GAMERS.
  std::cout << "Hello fellow cool kids! It's time to make a game!" << endl
       << "For our game today, we will be making a zoo! THat's right, "
          "everyone's favorite thing!"
       << endl;
  std::cout << "There are 4 types of animal in this zoo, because the god of this "
          "program decided so."
       << " Anyways, there's Bird, Fish, Lion, and bug." << endl;

  // while loop to add animal to zoo.
  string k;
  bool l=true;
  string name;
  int age;
  string noise;
  while (l) {
    std::cout
        << "So, what would you like to add?(Type \"Bird\", \"Fish\", \"Lion\", "
           "or \"Bug\") You can add any amount of animal you want! At least "
           "until you type \"stop\"."
        << endl;
    std::cin >> k;
    for (int i = 0; i < k.size(); i++) {
      k[i] = toupper(k[i]);
    }
    if(k=="STOP"){
      break;
    }
    std::cout << "Please enter name, age, and what noise it makes. (we need this "
            "for attraction)."<<endl;

    std::cin >> name;
    std::cin >> age;
    std::cin >> noise;



    // Push bird
    if (k == "BIRD") {
      zoo.push_back(new Bird(name, age, noise));
      std::cout << "You added " << name << " into the zoo!"<<endl;
    }
    // Push fish
    else if (k == "FISH") {
      zoo.push_back(new Fish(name, age, noise));
      std::cout << "You added " << name << " into the zoo!"<<endl;
    }
    // Push Lion
    else if (k == "LION") {
      zoo.push_back(new Lion(name, age, noise));
      std::cout << "You added " << name << " into the zoo!"<<endl;
    }
    // Push bug
    else if (k == "BUG") {
      zoo.push_back(new Bug(name, age, noise));
      std::cout << "You added " << name << " into the zoo!"<<endl;
    }
     else {
      std::cout << "Type properly please." << endl;
    }
  }

  std::cout << "Congratulations, you finished typing in animals. ";

  string stop;
  l=true;
  while (l==true) {
    std::cout << "Type in name of animal you want to interact with." << endl;
    std::cin >> name;
    for (int i = 0; i < zoo.size(); i++) {
      if (typeid(*zoo[i]) == typeid(Fish))
        if (dynamic_cast<Fish *>(zoo[i])->getName2() == name) {
          interact(dynamic_cast<Fish *>(zoo[i]));
        }

        else if (typeid(*zoo[i]) == typeid(Lion))
          if (dynamic_cast<Lion *>(zoo[i])->getName2() == name) {
            interact(dynamic_cast<Lion *>(zoo[i]));
          }

          else if (typeid(*zoo[i]) == typeid(Bug))
            if (dynamic_cast<Bug *>(zoo[i])->getName2() == name) {
              interact(dynamic_cast<Bug *>(zoo[i]));
            }

            else if (typeid(*zoo[i]) == typeid(Bird))
              if (dynamic_cast<Bird *>(zoo[i])->getName2() == name) {
                interact(dynamic_cast<Bird *>(zoo[i]));
              } else {
                std::cout << "Name does not exist. Please type again.";
              }
    }
    std::cout<<"What a nice interaction that was! if you want to stop playing type stop, else type anything!"<<endl;
    std::cin>>stop;
    for (int i = 0; i < stop.size(); i++) {
      stop[i] = toupper(stop[i]);
    }
    if(stop=="STOP"){
      std::cout<<"Thank you for playing, good bye!";
      return 0;
    }
  }
  return 0;
}

我想制作一个 function ，它可以通过传递指向这些类的指针与所有不同的派生类进行交互，但是当我尝试这样做时总是会出现许多类型的错误。 Bird、Bug、Fish 和 Lion 都有 unique() 和 makeNoise()，（但在 Animal.h 中不存在 unique，makeNoise 是虚拟的）。

请帮忙！
