Smart Pointers :
"In C++, an object that implements the functionality of a pointer and additionaly performs some action whenever an object is accessed through it. Smart pointers are implemented by overloading the pointer-derefrence(->) operator".

above is about smart pointers,
but
how to overload the -> operator?
how to implement a "smart pointers"?
and are "smart pointers" useful?
are the FAQ of "smart pointers".
in this part I show that how to overload the -> operator by this example:




  class sp1

  {

       public:

           int data;

           sp1* operator ->() { return this;};

  };



  int main()

  {

       sp1 t;

       cin >> t.data;

       cout << t->data;

  }

see that (->) operator work the same as (.) operator.
NOTE:
(.) oprator can't be overloaded.
GoodLuck.

You dont explain the part about the pointer being smart, how is that part used and how would one benefit from it in a program. kind of brief description.

still good effort
