_ Design of reusable components

Object Characteristics

1. An identity (a reference to a memory block that holds its state and behavior).

2. A state (its data, property, field sand attributes).

3. A behavior (method or methods that can manipulate the state of the object). Procedure
oriented language
Procedure oriented language । A Jarge program in =C‘splits into the simpler functional

blocks and statements. =C‘ is called procedure oriented language.

Object Oriented Language Characteristics

* A large program in objected oriented language C++ or Java, splits into the logical groups

(also known as classes).

٠ Each class defines the data and functions (methods) of using data.

٠ Each class can inherit another class element.

٠ A set of these groups (classes) then gives an application program of the Embedded

System

٠ Each group has internal user-level fields for data and has methods of processing that data
at these fields

* Each group can then create many objects by copying the group and making it functional.

* Each object is functional. Each object can interact with other objects to process the user's
data.

* The language provides for formation of classes by the definition of a group of objects

having similar attributes and common behavior. A class creates the objects. An object is
