Difference Between Procedural and Object-Oriented Programming

By Mohit Uniyal|Updated : April 22nd, 2022

Difference Between Procedural and Object-Oriented Programming: There are various levels of the programming language used to develop applications. Procedural and Object-oriented programming languages are high-level languages. Both languages follow varied approaches to the development of the program. The major difference between Procedural and Object-oriented programming is that POP follows a top-down approach whereas OOPs follow a bottom-up approach. 

Procedural oriented programming is also known as POP and Object-oriented programming is known as OOP. In the coming sections will see in detail the difference between Procedural and Object-Oriented Programming along with a few examples.

What is Procedural-Oriented Programming?

Before learning about the difference between Procedural and Object-Oriented programming we will first learn about Procedural-Oriented programming or POP in brief. It is the programming language that is based on structured programming. The code in POP is written in order to break down the tasks into data structures, subroutines, and a collection of variables. 

POP is the oldest form of programming language. The codes in the POP generally carry sequences of procedural steps that will be performed during the running of the program. Examples of Procedural-Oriented programming are C, BASIC, PASCAL, COBOL, FORTRAN, etc. 

What is Object-Oriented Programming?

 The Object-Oriented programming or OOP is another type of high level programming language. The OOP is based on the concept of object. It one of the most widely used programming language. The Object in OOP are instances of classes which are known as the blueprint of object.

The Object-Oriented programming is most popular programming language which carries data as attributes and code as methods. The popular example of OOP are Java, C++, C#, Python, Objective-C, Scala, PHP, JavaScript, Dart, Swift, Ruby, Perl, etc. 

Let us now see the some differences between the Procedural and Object-Oriented programming in the coming section.

Difference Between Procedural and Object-Oriented Programming

Altough there are various similarities between Procedural and Object-Oriented Programming such as both are programming language which carry data types like string, float, etc. Here is the list of difference between the Procedural and Object-Oriented programming in the table provided below:

Access modifiers are not supported.Access modifiers are supported.
Functions are preferred over data.Security and accessibility is preffered.

If size of the problem is small, POP is preffered.If the size of the provble is big, OOP is preffered.

FAQs

  • The major difference Between Procedural and Object-Oriented Programming is that procedural-oriented programming language is procedure dependent and OOPs is object dependent. Both of the programming languages are different with respect to flow approach as well.

  • Object-Oriented Programming or OOP is a high level programming language which is based on concept of object. OOPs is widely used nowadays and follow bottom-up approach. Example of OOP are  Java, C++, C#, Python, Objective-C, Scala, PHP, JavaScript, Dart, Swift, Ruby, Perl, etc.

  • Procedural-Oriented Programming is also a type of high level programming language which is based on the concept of procedure. POP uses top-down approach. A few examples of POP are C, BASIC, PASCAL, COBOL, FORTRAN, etc. 

  • As per the approach, the major difference between Procedural and Object-Oriented programming is that POP follows a top-down approach whereas OOPs follow a bottom-up approach. The approach of both the programming language is opposite to each other.

  • Along with various differences between the two, there are a few similarities between Procedural and Object-Oriented Programming which are:

    • Both the languages carry primitive data types.
    • Both use basic loops and statements.
    • The approaches of both the language are different but solves the same purpose of executing and running the program in order to complete the given task.
