Procedural Oriented ProgrammingObject-Oriented Programming

In procedural programming, the program is divided into small parts called functions.In object-oriented programming, the program is divided into small parts called objects.

Procedural programming follows a top-down approach.Object-oriented programming follows a bottom-up approach.

There is no access specifier in procedural programming.Object-oriented programming has access specifiers like private, public, protected, etc.

Adding new data and functions is not easy.Adding new data and function is easy.

Procedural programming does not have any proper way of hiding data so it is less secure.Object-oriented programming provides data hiding so it is more secure.

In procedural programming, overloading is not possible.Overloading is possible in object-oriented programming.

In procedural programming, there is no concept of data hiding and inheritance.In object-oriented programming, the concept of data hiding and inheritance is used.

In procedural programming, the function is more important than the data.In object-oriented programming, data is more important than function.

Procedural programming is based on the unreal world.Object-oriented programming is based on the real world.

Procedural programming is used for designing medium-sized programs.Object-oriented programming is used for designing large and complex programs.

Procedural programming uses the concept of procedure abstraction.Object-oriented programming uses the concept of data abstraction.

Examples: C, FORTRAN, Pascal, Basic, etc.Examples: C++, Java, Python, C#, etc.
