Revision of C++ PROGRAMMING Taught in XI:
REVIEW: C++ covered In Class -XI
2.Include all the points
discussed during April-May 2013 class room transactions :
Object Oriented Programming:
Concept of Object Oriented Programming - Data
hiding, Data encapsulation, Class and Object, Abstract
class and Concrete class, Polymorphism
(Implementation of polymorphism using Function overloading
as an example in C++); Inheritance, Advantages of
Object Oriented Programming over earlier
programming methodologies,
Implementation of Object Oriented Programming
concepts in C++:
Definition of a class, Members of a class - Data
Members and Member Functions (methods), Using
Private and Public visibility modes, default
visibility mode (private); Member function definition: inside
class definition and outside class definition using
scope resolution operator (::); Declaration of objects
as instances of a class; accessing members from
object(s), Objects as function arguments - pass by
value and pass by reference;
Constructor and Destructor:
Constructor: Special Characteristics, Declaration
and Definition of a constructor, Default Constructor,
Overloaded Constructors, Copy Constructor,
Constructor with default arguments;
Destructor: Special Characteristics, Declaration and definition of destructor;
Inheritance (Extending Classes):
Concept of Inheritance, Base Class, Derived Class,
Defining derived classes, protected visibility mode;
Single level inheritance, Multilevel inheritance
and Multiple inheritance, Privately derived, Publicly derived
and Protectedly derived class, accessibility of
members from objects and within derived class(es);
