Answer 1

#include <bits/stdc++.h>


using namespace std;






class Fruit


{


public:


  static int fruitCounter;


  Fruit()


  {


    fruitCounter++;


  }


  ~Fruit()


  {


    fruitCounter--;


  }


};






class Apples: public Fruit


{


public:


  static int applesCounter;


  Apples():Fruit()


  {


    applesCounter++;


  }


  ~Apples()


  {


    applesCounter--;


  }






};






class Mangoes: public Fruit


{


public:


  static int mangoesCounter;


  Mangoes():Fruit()


  {


    mangoesCounter++;


  }


  ~Mangoes()


  {


    mangoesCounter--;


  }


};






int Fruit::fruitCounter = 0;


int Apples::applesCounter = 0;


int Mangoes::mangoesCounter = 0;






int main()


{


  Apples firstApple,secondApple,thirdApple;


  Mangoes firstMango,secondMango,thirdMango,fourthMango;


  cout << "Total number of fruits: " << Fruit::fruitCounter << endl;


  cout << "Number of apples: " << Apples::applesCounter << endl;


  cout << "Number of mangoes: " << Mangoes::mangoesCounter << endl;


  return 0;


}
