This article focuses on discussing the differences between procedural and object-oriented programming.
Procedural Programming
Procedural Programming can be defined as a programming model which is derived from structured programming, based upon the concept of calling procedure. Procedures, also known as routines, subroutines or functions, simply consist of a series of computational steps to be carried out. During a program’s execution, any given procedure might be called at any point, including by other procedures or itself.
Languages used in Procedural Programming:
FORTRAN, ALGOL, COBOL,
BASIC, Pascal and C.
Object-Oriented Programming
Object-oriented programming can be defined as a programming model which is based upon the concept of objects. Objects contain data in the form of attributes and code in the form of methods. In object-oriented programming, computer programs are designed using the concept of objects that interact with the real world. Object-oriented programming languages are various but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types.
Languages used in Object-Oriented Programming:
Java, C++, C#, Python,
PHP, JavaScript, Ruby, Perl,
Objective-C, Dart, Swift, Scala.
Procedural Programming vs Object-Oriented Programming
Below are some of the differences between procedural and object-oriented programming:
Procedural Oriented Programming Object-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. Code reusability absent in procedural programming, Code reusability present in object-oriented programming. Examples: C, FORTRAN, Pascal, Basic, etc. Examples: C++, Java, Python, C#, etc.

Difference between Procedural and Non-Procedural language
Procedural Language: In procedural languages, the program code is written as a sequence of instructions. User has to specify "what to do" and also "how to do" (step by step procedure). These instructions are executed in the sequential order. These instructions are written to solve specific problems. Examples of Procedural languages: FORTRAN, COBOL,

Difference between Function Oriented Design and Object Oriented Design
1. Function Oriented Design : Function oriented design is the result of focusing attention to the function of the program. This is based on the stepwise refinement. Stepwise refinement is based on the iterative procedural decomposition. Stepwise refinement is a top-down strategy where a program is refined as a hierarchy of increasing levels of deta

Difference Between Object-Oriented Testing and Agent-Oriented Testing
Agent-oriented Testing is defined as the application of agents like software or intelligent or multi-agent systems, etc. to software testing problems by tackling and automating complex testing tasks. This testing is considered an extension of the object-oriented testing process. There is a growing need for agent-oriented systems to tackle complex p

Difference between Functional Programming and Object Oriented Programming
A programming paradigm is a style, or “way, ” of programming. Programming paradigms differ from one another based on the features and the style they support. There are several features that determine a programming paradigm such as modularity, objects, interrupts or events, control flow etc. Every programming paradigm has its own advantage so, it be

Difference between Row oriented and Column oriented data stores in DBMS
Row-oriented and column-oriented data stores are two different approaches to storing and organizing data in relational database management systems (RDBMS).

Difference between Procedural and Declarative Knowledge
Procedural Knowledge: Procedural Knowledge also known as Interpretive knowledge, is the type of knowledge in which it clarifies how a particular thing can be accomplished. It is not so popular because it is generally not used. It emphasize how to do something to solve a given problem. Let's see it with an example: var a=[1, 2, 3, 4, 5]; var b=[]; f

Design Goals and Principles of Object Oriented Programming
The fundamental goal of dealing with the complexity of building modern software naturally gives rise to several sub-goals. These sub-goals are directed at the production of quality software, including good implementations of data structures and algorithms. The article focuses on discussing design goals and principles of Object Oriented Programming.

Object-Oriented Programming in Ruby | Set 1
When we say object-oriented programming, we mean that our code is centered on objects. Objects are real-life instances that are classified into various types. Let’s take an example to understand this better. If we consider a rose as an object, then the class of the rose will be flower. A class is like the blue-print of an object and describes the a
