Advantages of OOPS Concepts: OOPS provides many features for both Program Designer and Program User. Programs developed by OOPS have the following characteristics:

  • Data has importance rather than procedures in the problem. That is, in OOPS the data is kept at the primary level and the functions of the operations performed on the data are kept at the secondary level.
  • The problem is divided into Objects rather than divided into Functions.
  • The data structure is designed in such a way that characterizes the object.
  • Functions of the operations that are performed on the data have been combined with the data structure of the object, which is called  Encapsulation  .
  • Only the functions associated with the data can be accessed, so that the data remains hidden for external functions. This process is called Data Hiding in  OOPS  .
  • Objects communicate with each other through functions. This process is called  Message Passing  .
  • If required, the new Data and Operations to be performed on the data can be added to the object. This process is called Inheritance in OOPS   .
  • OOPS Approach in Program Design is called Bottom-Up Approach .
  • Using Inheritance , a Programmer avoids writing the same Coding again and again. He  is able to reuse a written Coding repeatedly . Reuse of coding makes it easier for the programmer to develop the program and it becomes easier to maintain the program.
  • Since the Program in OOPS Data fully Outer World Hide lives. Only authorized Member Functions to access the data are able to access that data. Since no unauthorized External Function Access is able to access the program's data, the data is protected by Accidental Modifications.
  • Multiple Instances of the same Object can be Exist simultaneously in the same Program without any interference.
  • By dividing the program into objects, the program is able to represent Real World Concepts logically much better in Computer.
  • Upgrade, Modify and Change Application based on OOPS is quite simple and convenient.
  • Solutions to very complex problems can also be developed and managed in an easy way on the basis of OOPS Concept.

Object Oriented Languages

Concepts of OOPS to as "C" or "Pascal" Procedural Languages may be fully Implement. But when we try to implement the concepts of OOPS in a procedural language like "C", then we have to face many other Compiler related limitations. Whereas when using a compiler designed keeping in mind the OOPS like "C ++", we do not have to face these kinds of problems. Regarding implementing OOPS also, we can divide Programming Languages ​​into two parts-

Object-Based Programming Language

Visual – Basic of Microsoft Company is an Object Based Programming Language. This type of Programming Languages   supports Encapsulations  and  Object Identity . The main features of Object Based Programming Languages ​​are Encapsulation, Data Hiding and Access Mechanism, Automatically Initialize and Clear Objects and Operator Overloading . Object-based programming languages ​​do not support Inheritance and Dynamic Binding. Languages ​​that make it possible to use Programming using Objects are called Object-Based Programming Languages.

Object-Oriented Programming Language

Object Oriented Programming has all the features of Object Based Programming along with Inheritance and Dynamic Binding . "C ++" is a hybrid language, as it supports Procedural Programming as well as Object Oriented Programming.
