    int size; // number of students


  public:
    Students() {
      this->size = 0;
    }


    Students(const Students &other) {
      this->size = other.getSize();
    }


    void setSize(int size) {
      this->size = size;
    }


    int getSize() const {
      return this->size;
    }
};


int main() {
  // Create object using default constructor
  Students students1;
  students1.setSize(10);
  cout << "Students 1 has size " << students1.getSize() << endl;


  // Create object using copy constructor
  Students students2 = students1;
  students2.setSize(20);
  cout << "Students 2 has size " << students2.getSize() << endl;
}
