1. Object-Oriented Programming Concepts: Introduction, comparision between procedural
programming paradigm and object-oriented proramming paradigm, basic concepts of objectoriented
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. 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. 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. 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

operators, overloading of various operators, type conversion - basic type to class type, class type to
basic type, class type to another class type.
