PROCEDURAL ORIENTED PROGRAMMING VS OBJECT ORIENTED PROGRAMING
- 1. TAE 2 Subject: Object Oriented Programming Topic: Procedure Oriented Programming vs. Object Oriented Programming Guided by: Ms. Diksha Bhoyar Group No : 06 (SCOB48) Uttam Singh
- 2. Procedure Oriented Programming Object Oriented Programming Program is divided into parts called objects. OOP has access specifiers named Public, Private, Protected, etc. Provides Data Hiding so provides more security. In OOP, overloading is possible in the form of Function Overloading and Operator Overloading. 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 OOP are : C++, JAVA, VB.NET, C#.NET. In POP, program is divided into small parts called functions. POP does not have any access specifiers (I.e) by default it is public only. POP does not have any proper way for hiding data so it is less secure. In POP, Overloading is not possible. In POP, Most function uses Global data for sharing that can be accessed freely from function to function in the system. Example of POP are : C, VB, FORTRAN, Pascal.
- 3. REAL TIME EXAMPES OF POPS AND OOPS WITH SOME SITUATION Suppose that we suddenly need to add a bus form, that records the following information: Color, Engine Size, Transmission Type Number of passengers Procedural: We need to recreate the entire form, repeating the code for Color, Engine Size, and Transmission Type. OOP: We simply extend the vehicle class with a bus class and add the method, number Of Passengers.
- 4. SITUATION 2 If the client in vehicle company wants to change the colors of all the vehicles for some reason. Procedural: We have to change three different forms: cars, trucks, and buses color differently one by one for the client as its follows procedure step by step . OOP: We change the color method in the vehicle class and because the car, truck, and bus classes all are inherited from one derived class they are automatically updated.
- 5. Procedure Oriented Programming Object Oriented Programming Advantages It is easy to understand. It models the real world(i.e) it can be easily extended. It offers reusability (i.e) already created classes can be reuse without having to write them again. These are easier to test and maintain. Disadvantages It needs a proper planning and proper designing Program designing is sometime tricky. Advantages Its relative simplicity, and ease of implementation of compilers and interpreters. An easier way to keep track of program flow. Needs only less memory. Disadvantages Data is exposed to whole program, so no security for data. The does not offer the ability to re-use the same code at different places. Difficult to relate with real world objects. Difficult to create new data types reduces extensibility.
