Difference Between Procedure Oriented Programming (POP) & Object Oriented Programming (OOP)

Procedure Oriented ProgrammingObject Oriented Programming
1Programs are divided into small parts called functions.Programs are divided into parts called Class.
2Importance is not given to data but to functions as well as sequence of actions to be done.Importance is given to the data rather than procedures or functions because it works as a real world.
3POP follows Top Down approach.OOP follows Bottom Up approach.
4POP does not have any access specifier.OOP has access specifiers named Public, Private, Protected, etc.
5Data can move freely from function to function in the system.Objects can move and communicate with each other through member functions.
6To add new data and function in POP is not so easy.OOP provides an easy way to add new data and function.
7Most 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.
8It does not have any proper way for hiding data, so it is less secure.OOP provides Data Hiding. so provides more security.
9Overloading is not possible.In OOP, overloading is possible in the form of Function Overloading and Operator Overloading.
10Example of Procedure Oriented Programming are : C, VB, FORTRAN,Pascal.Example of Object Oriented Programming are :C++, JAVA, VB.NET, C#.NET.
