- 2. Need of Object Oriented Programming DEPARTMENT OF COMPUTER ENGINEERING , SCOE,KOPARGAON 2 Why Do We Need Object‐Oriented Programming? • Object Oriented Programming was developed because limitations were discovered in earlier approaches to programming. • To appreciate what OOP does, we need to understand what limitations are there in earlier programming and how they differ from traditional programming languages.
- 3. POP Vs OOP DEPARTMENT OF COMPUTER ENGINEERING , SCOE,KOPARGAON 3 Procedure Oriented Programming Object Oriented Programming • In POP, program is divided into small parts called functions. • In OOP, program is divided into parts called objects. • POP does not have any access specifier. • OOP has access specifiers named Public, Private, Protected, etc • POP does not have any proper way for hiding data so it is less secure • OOP provides Data Hiding so provides more security • In POP,Overloading is not possible. • In OOP, overloading is possible in the form of Function Overloading and Operator Overloading. • In POP, most function uses Global data for sharing that can be accessed freely from function to function in the system. • In OOP, data can not move easily from function to function, it can be kept public or private so we can control the access of data. • Example of POP are : C, VB, FORTRAN, Pascal • Example of OOP are : C++, JAVA, VB.NET, C#.NET.
- 4. Features of OOP DEPARTMENT OF COMPUTER ENGINEERING , SCOE,KOPARGAON 4 • Data binding • Class & Object • Message passing • Encapsulation • Inheritance • Polymorphism • Abstraction • Method overloading • Method overriding • Exception handling (Due to these all features provided by OOP it makes OOP as best programming approach)
