Difference Between Procedure Oriented Programming (POP) & Object Oriented Programming (OOP)
| 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 areal 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. |
