Unit No.Unit NameMarks

Unit 1: Object Oriented Programming in C++ (50 Theory + 40 Practical) Periods
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, Member 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 (::); 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 Inheritances, Base Class, 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, 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 (), read (), put (), write(), getline() and close() functions; Detecting end-of-file (with or without using eof() function), tellg(), tellp(), seekg(), seekp();

Introduction to Pointer, Declaration and Initialization of Pointer; Dynamic memory allocation/deallocation 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 structure: De-reference/Deference operator: *, ->; self referential structure;

Unit 2: Data Structures: (42 Theory + 36 Practical) Periods
Introduction to data structure- array, stack queues primitive and non-primitive data structure,
linear and non-linear structure, static and dynamic data structure.

One and two Dimensional arrays: Sequential allocation and address calculation;
One dimensional array: Traversal, Searching (Linear, Binary Search), Insertion of an element in an array, deletion of an element from an array, Sorting (Insertion, Selection, Bubble)
Two-dimensional arrays: Traversal Finding sum/difference of two NxM arrays containing numeric values, Interchanging Row and Column elements in a two dimensional array;

Stack (Array and Linked implementation of Stack):
Introduction to stack (LIFO: Last in First out Operations)
Operations on stack (PUSH and POP) and its Implementation in C++, Converting expressions from INFIX to POSTFIX notation and evaluation of Postfix expression;
Queue: (Array and Linked Implementation)
Introduction to Queue (FIFO: First in First out operations)
Operations on Queue (Insert and Delete and its Implementation in C++, circular queue using array.

Unit 3: Database Management System and SQL: (20 Theory + 20 Practical) Periods
Data base Concepts: Introduction to data base concepts and its need.
Relational data model: Concept of domain, tuple, relation, key, primary key, alternate key,
candidate key;
Relational algebra: Selection, Projection, Union and Cartesian product;
Structured Query Language:
General Concepts: Advantages of using SQL, Data Definition Language and Data Manipulation Language;
SQL functions: SUM ( ), AVG ( ), COUNT ( ), MAX ( ) AND MIN ( ); Obtaining results (SELECT query) from 2 tables using equi-join, Cartesian product and Union
Note: Implementation of the above mentioned commands could be done on any SQL supported software on one or two tables.

Unit 4: Boolean Algebra: (16 Theory + 0 Practical) Periods
Role of Logical Operations in Computing.
Binary-valued Quantities, Boolean Variable, Boolean Constant and Boolean Operators: AND, OR, NOT; Truth Tables; Closure Property, Commutative Law, Associative Law, Identity law, Inverse Law, Principle of Duality, Idempotent Law, Distributive Law, Absorption Law, Involution Law, DeMorgan’s Law and their applications;
