PART-A
1. Object-Oriented Programming Concepts: Introduction, comparision between procedural programming
paradigm and object-oriented proramming paradigm, basic concepts of object-oriented programming —
concepts of an object and a class, interface and implementation of a class, operations on objects, relationship
among objects, abstraction, encapsulation, data hiding, inheritance, overloading, polymorphism, messaging.
[2]
2. Standard Input/Output: Concept of streams, hierarchy of console stream classes, input/output using
overloaded operators >> and << and memberv functions of i/o stream classes, formatting output, formatting
using ios class functions and flags, formatting using manipulators. [3]
3. Classes and Objects: Specifying a class, creating class objects, accessing class members, access specifiers,
static members, use of const keyword, friends of a class, empty classes, nested classes, local classes, abstract
classes, container classes, bit fields and classes. [4]
4. Pointers and Dynamic Memory Management: Declaring and initializing pointers, accessing data through
pointers, pointer arithmetic, memory allocation (static and dynamic), dynamic memory management using new
and delete operators, pointer to an object, this pointer, pointer related problems - dangling/wild pointers, null
pointer assignment, memory leak and allocation failures. [5]
5. Constructors and Destructors: Need for constructors and destructors, copy constructor, dynamic
constructors, explicit constructors, destructors, constructors and destructors with static members, initializer
lists. [2]
6. Operator Overloading and Type Conversion: Overloading operators, rules for overloading operators,
overloading of various operators, type conversion - basic type to class type, class type to basic type, class type
to another class type. [4]
PART-B
7. Inheritance: Introduction, defining derived classes, forms of inheritance, ambiguity in multiple and multipath
inheritance, virtual base class, object slicing, overriding member functions, object composition and delegation,
order of execution of constructors and destructors. [5]
8. Virtual functions & Polymorphism: Concept of binding - early binding and late binding, virtual functions,
pure virtual functions, abstract clasess, virtual destructors. [3]
9. Exception Handling: Review of traditional error handling, basics of exception handling, exception handling
mechanism, throwing mechanism, catching mechanism, rethrowing an exception, specifying exceptions.
[2]
10. Templates and Generic Programming: Template concepts, Function templates, class templates, illustrative
examples. [3]
11. Files: File streams, hierarchy of file stream classes, error handling during file operations, reading/writing of
files, accessing records randomly, updating files.
