UNIT 1: OBJECT ORIENTED PROGRAMMING IN C++

REVIEW: C++ covered In Class -XI, 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);

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(),

PART A: Accounting for Partnership Firms and Companies

Unit 1. Accounting for Partnership firms - Fundamentals

• Partnership : features, Partnership deed.
• Provisions of the Indian Partnership Act 1932 in the absence of partnership deed.
• Fixed v/s fluctuating capital accounts, division of profit among partners, guarantee of profits, past adjustments (relating to interest on capital, interest on drawing, salary and profit sharing ratio), preparation of P&L Appropriation account.
• Goodwill: nature, factors affecting and methods of valuation - average profit, super profit, and capitalization
