  Constructor (1. Default, 2. copy, 3. move)
  Assignment Operator(4. Copy, 5. move assigment operator)
  6. Destructor
Characteristics of OOPS
  1. Polymorphism
  |- Static(CompileTime)
    |- Templates(Class, Function, Variadic Templates, Template Parameter Pack)
    |- Operator Overloading
  |- Dynamic(Runtime): Virtual Functions
 2. Association: Composition , Aggregation
 3. Generalization = Inheritance
 4. Abstraction
 5. Classes, Objects, Data hiding
 6. Encapsulation
Exception Handling
