Procedure Oriented Programming |
Object Oriented Programming |
Divided Into |
In POP, program is divided into small parts called functions. |
In OOP, program is divided into parts called objects. |
Importance |
In POP,Importance is not given to data but to functions as well as sequence of actions to be done. |
In OOP, Importance is given to the data rather than procedures or functions because it works as a real world. |
Approach |
POP follows Top Down approach. |
OOP follows Bottom Up approach. |
Access Specifiers |
POP does not have any access specifier. |
OOP has access specifiers named Public, Private, Protected, etc. |
Data Moving |
In POP, Data can move freely from function to function in the system. |
In OOP, objects can move and communicate with each other through member functions. |
Expansion |
To add new data and function in POP is not so easy. |
OOP provides an easy way to add new data and function. |
Data Access |
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. |
Data Hiding |
POP does not have any proper way for hiding data so it is less secure. |
OOP provides Data Hiding so provides more security. |
Overloading
|
In POP, Overloading is not possible. |
In OOP, overloading is possible in the form of Function Overloading and Operator Overloading. |
Examples |
Example of POP are : C, VB, FORTRAN, Pascal. |
Example of OOP are : C++, JAVA, VB.NET, C#.NET. |
