CLASS AND OBJECT

C# class and object

Whenever we start programming in C# or Object based Compiler. Then we have to instantiate Object. Thus we use maximum Object to categories the program into small part to optimize its complexity and length.

CLASS

            “The class is also known as classification that is the specification or characteristic of any object.” 

Or

            “Information about any object is known as classification”.      

For example for an Object of student its name, roll no, and student ID may be its class.

CLASS MEMBERS

There are five class members who classify a class and classes classify the objects which are.

           1.    Constructors

           2.    Methods

           3.    Destructors

           4.    Instance variable

           5.    Properties  

SYNTAX

Public Class Classname

{

Public members;

}

Program examples of class and object.

OBJECT

            “Object is a physical instance that is classified by the class. Number of class makes an object”. Object is use to implement that program in real life.

For example suppose student is an object.

OBJECT INSTANTIATE SYNTAX

Classname Obj = new Classname ( );

 Let suppose student is a class. How the object could will be for class student.

Student Obj = new Student ( );

WHY WE USE OBJECT?

            Object is made due to the following reason.

            1.    To categories the program code into parts for better understands.

            2.    For the reusability of block of code.

            3.    To utilize less memory storage.

            4.    To overcome program complexity.

            5.    To manage the time to written codes.

            6.    To overcome the execution time of program.

            7.    To maintain the minimum length of program.
