Unit 1: Object Oriented Programming in C + +
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 classes.
Data File Handling:	Need for a data file, Types of data files-Text file and Binary file. Text File: Basic file operations on text file: Creating/Writing text into file, Reading and Manipulation of text from an already existing text File (accessing sequentially) Binary File: Creation of file, Writing data into file, Searching for required data from file, Appending data to a file, Insertion of data in sorted file, Deletion of data from file, Modification of data in a file; Implementation of above mentioned data file handling in C + +; Components of C + + to be used with file handling: Header file: Fstream. h; ifstream, ofstream, fstream classes; Opening a text file in in, out, and app modes Using cascading operators (>> <<) for writing text to the file and reading text from the file; open (), get (), put (), getline () and close () functions; Detecting end-of-file (with or without using eof () function); Opening a binary file using in, out, and app modes; open (), read (), write () and close () functions; Detecting end-of-file (with or without using eof () function); tellg (), tellp (), seekg (), seekp () functions.
Pointers:	Introduction to Printer, Declaration and Initialization of Pointers; Dynamic memory allocation/de-allocation operators: New, delete; Pointers and Arrays: Array of Pointers, Pointer to an array (1 dimensional array), Function returning a pointer, Reference variables and use of alias; Function call by reference. Pointer to structures: De-reference/Deference operator: *, → self referencial structures.
