Why should I use a pointer rather than the object itself?

Question

I\'m coming from a Java background and have started working with objects in C++. But one thing that occurred to me is that people often use pointers to objects rather than t

Answer 1

I will include one important use case of pointer. When you are storing some object in the base class, but it could be polymorphic.

Class Base1 {
};

Class Derived1 : public Base1 {
};


Class Base2 {
  Base *bObj;
  virtual void createMemerObects() = 0;
};

Class Derived2 {
  virtual void createMemerObects() {
    bObj = new Derived1();
  }
};

So in this case you can't declare bObj as an direct object, you have to have pointer.
