Course Objective

Objective of this course is to make students familiar with the concepts of object-oriented programming

Concepts will be reinforced by their implementation in C++

What is Object-Orientation?

A technique for system modeling

OO model consists of several interacting objects

What is a Model?

A model is an abstraction of something

Purpose is to understand the product before developing it

Examples – Model

Highway maps

Architectural models

Mechanical models

Example – OO Model

Object-Orientation - Advantages People think in terms of objects

OO models map to reality

Therefore, OO models areeasy to developeasy to understand

What is an Object?An object is

Something tangible (Ali, Car)

Something that can be apprehended intellectually (Time, Date)

… What is an Object?An object has

State (attributes)Well-defined behaviour (operations)Unique identity

Example – Ali is a Tangible ObjectState (attributes)

NameAge

behaviour (operations)WalksEats

IdentityHis name

Example – Car is a Tangible ObjectState (attributes)

- Color- Model

behaviour (operations)- Accelerate - Start Car- Change Gear

Identity- Its registration number

Example – Time is an Object Apprehended IntellectuallyState (attributes)

- Hours - Seconds- Minutes

behaviour (operations)- Set Hours - Set Seconds- Set Minutes

Identity- Would have a unique ID in the model

Example – Date is an Object Apprehended IntellectuallyState (attributes)

- Year - Day- Month

behaviour (operations)- Set Year - Set Day- Set Month

Identity- Would have a unique ID in the model
