This document discusses object oriented software engineering and programming. It outlines the agenda which includes an introduction to procedural and object oriented approaches, comparing the two, and reviewing object oriented concepts, analysis, design and development. Key reasons given for using object oriented programming are that it makes code maintenance and modification easier through inheritance, improves understandability and ease of development for new programmers, and increases efficiency by freeing up unused memory. Core object oriented concepts covered are objects, classes, abstraction, encapsulation, inheritance, constructors, destructors, and polymorphism.

4. OBJECT ORIENTED PROGRAMING (REASONS)
 One reason to use Object-oriented Programming is
because it makes it easy to maintain and modify
existing code as new objects are created inheriting
characteristics from existing ones. This cuts down
the development time considerably and makes
adjusting the program much simpler.

5. OBJECT ORIENTED PROGRAMING (REASONS)
 Another reason to use Object-oriented
Programming is the ease of development and
ability for other developers to understand the
program after development. Well commented
objects and classes can tell a developer the
process that the developer of the program was
trying to follow. It can also make additions to the
program much easier for the new developer.

6. OBJECT ORIENTED PROGRAMING (REASONS)
 The last reason to use Object-oriented
Programming that I will mention here is the
efficiency of the language. Many programming
languages using Object-oriented Programming will
dump or destroy unused objects or classes freeing
up system memory. By doing this the system can
run the program faster and more effectively.

7. OBJECT ORIENTED PROGRAMING CONCEPTS
 Objects(different instances of classes)
 Classes (blueprint for objects)
 Abstraction(focus on the essentials and discard the
extra things)
 Encapsulation
 Inheritance
 Constructors and destructors
 Polymorphism
