CBSE class 12 Computer Science C++ New Syllabus 2018-19

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 (::); 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 Inheritances, Base Class, Derived classes, protected
visibility mode; Single level inheritance, Multilevel inheritance and Multiple inheritance, Privatelyderived, 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 referencial
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 Systema and SQL
Common to both the options. Refer to unit 3 DATABASE AND SQL mentioned in case of Python for
further details.
Unit 4: Boolean Algebra
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;
Obtaining Sum of Product (SOP) and Product of Sum (POS) form the Truth Table, Reducing Boolean
Expression (SOP and POS) to its minimal form, Use of Karnaugh Map for minimization of Boolean
expressions (up to 4 variables);
Application of Boolean Logic: Digital electronic circuit design using basic Logic Gates (NOT, AND,
Use of Boolean operators (NOT, AND, OR) in SQL SELECT statements
Use of Boolean operators (AND, OR) in search engine queries.
Unit 5: Networking and Open Source Software
Evolution of Networking: ARPANET, Internet, Interspace Different ways of sending data across
the network with reference to switching techniques (Circuit and Packet switching).
Data Communication terminologies: Concept of Channel, Bandwidth (Hz, KHz, MHz) and Data
transfer rate (bps, Kbps, Mbps, Gbps, Tbps).
Transmission media: Twisted pair cable, coaxial cable, optical fiber, infrared, radio link,
microwave link and satellite link.
Network devices: Modem, RJ45 connector, Ethernet Card, Router, Switch, Gateway, wifi card.
Network Topologies and types: Bus, Star, Tree, PAN, LAN, WAN, MAN.
Network Protocol: TCP/IP, File Transfer Protocol (FTP), PPP, SMTP, POP3 Remote Login (Talent),
and Internet Wireless/Mobile Communication protocol such as GSM, CDMA, GPRS, and WLL.
Mobile Telecommunication Technologies : 1G, 2G, 3G and 4G
Electronic mail protocols such as SMTP, POP3
Protocols for Chat and Video Conferencing VOIP
Wireless technologies such as Wi-Fi and WiMax
Network Security Concepts:
Threats and prevention from Viruses, Worms, Trojan horse, Spams
Use of Cookies, Protection using Firewall.
India IT Act, Cyber Law, Cyber Crimes, IPR issues, hacking.
Introduction To Web services: WWW, Hyper Text Markup Language (HTML), Extensible Markup
Language (XML); Hyper Text Transfer Protocol (HTTP); Domain Names; URL; Website, Web
browser, Web Servers; Web Hosting, Web Scripting – Client side (VB Script, Java Script, PHP) and
Server side (ASP, JSP, PHP), Web 2.0 (for social networking)
of Python for further details.
