Functional Programming and Procedural Programming Video & Lesson Transcript

These languages are the exception to the common ground between procedural and functional languages. The programming paradigm where everything is represented as an object is known as a truly object-oriented programming language. Smalltalk is said to be the first truly object-oriented programming language. The procedure-oriented programming paradigm, on the other hand, works with extremely small memory. Object-oriented programming is a programming paradigm that stores data and code in “objects” .

In this article we’re going to take a look at programming paradigms, a fancy title to describe popular ways or styles to organize your programming. In object-oriented programming, you still have to write out the lyrics and music notes of the song, but only once, and then any band can use the lyrics and music at any time. From now on, every other program can call the same object and play the song.

This article will not join into those discussions though – instead, we’ll dive into three very important ways of writing code and compare them. The use of objects makes it possible to lessen and _____ code. _____ is extensible templates for creating objects, providing initial values for state and implementations of its behavior. OOP is known as a problem-solving approach in which data computation is carried out in terms of _____.

By the same token, procedure calls correspond to function application.

• If you want a computer to do something, you should provide step-by-step instructions on how to do it.
• There do exist a few esoteric functional languages that eschew structured programming precepts for the sake of being difficult to program in .
• You can think of a class as a concept and the object as the embodiment of that concept.
• One of the most important characteristics of procedural programming is that it relies on procedures that operate on data – these are two separate concepts.
• Procedural programming is also referred to as imperative programming.
• Object-oriented components were added to C to become C++, which is therefore both a procedural and object-oriented language.

Inputs are usually specified syntactically in the form of arguments and the outputs delivered as return values. The core concept of OOP is to separate concerns into entities which are coded as objects. Each entity will group a given set of information and actions that can be performed by the entity. See that we’re telling the program to iterate through each element in the array, compare the item value with 5, and if the item is bigger than 5, push it into an array. Moreover, these terms are used a lot in the coding world, so having a basic understanding will help you better understand other topics as well.

#Procedural Programming

The meaning of oriented is interested in a particular kind of thing or entity. In layman’s terms, it is a programming pattern that rounds around an object or entity. Object-oriented programming and procedural programming both are used to develop the applications. These two are important concepts, and it is also important to know the difference between them.

Object-oriented programming has become the dominant programming paradigm in today’s software development, but procedural programming languages are still widely used. Procedural programming is a programming paradigm, derived from imperative programming, based on the concept of the procedure call. Procedures simply contain a series of computational steps to be carried out.

Differences between Procedural and Object Oriented Programming

The focus of procedural programming is to break down a programming task into a collection _____. In logic programming, a program is a set of premises, and computation is performed by attempting to prove candidate theorems. From this point of view, logic programs are declarative, focusing on what the problem is, rather than on how to solve it. Both allow the reuse of the same code in various parts of the programs, and at various points of its execution. C++, Python, and Java are well-known examples of languages that support the OOP paradigm.

It follows a step-by-step approach in order to break down a task into a set of variables and routines via a sequence of instructions. Object-oriented programming is a top-down method of programming that uses the notion of objects to interact with the actual world. The majority of widely used programming languages, such asC++, Python, and Java, employ a variety of paradigms, including the object-oriented programming paradigm. The procedural-oriented programming paradigm is developed from the imperative programming model, whereas the declarative programming paradigm is related to the OOP paradigm.

Procedural-oriented languages use a top-down approach to problem-solving, breaking down a huge complicated problem into smaller sections that may be explored separately. In procedural programming, the fundamental strategy is to break down a difficult problem into smaller parts that are easier to comprehend, handle, and manage. Procedural programming refers to a series of instructions that inform a computer what it should do step-by-step to achieve the task. I’m a full stack dev (javascript | typescript | react | react native | node) and computer science student. Here I write about the things I learn along my path to becoming the best developer I can be. Functional programming takes the concept of functions a little bit further.

• See that we’re telling the program to iterate through each element in the array, compare the item value with 5, and if the item is bigger than 5, push it into an array.
• This makes it possible to create more complicated behavior with less code.
• What declarative programming does is to hide away that complexity from the direct view of the programmer.
• In object-oriented programming, you organize your code by creating objects, and then you can give those objects properties and you can make them do certain things.
• OOP is known as a problem-solving approach in which data computation is carried out in terms of _____.
• Two of the most important programming paradigms are procedural programming and object-oriented programming.

JavaScript’s filter, map, reduce and sort functions are good examples of declarative code. Imperative programming consists of sets of detailed instructions that are given to the computer to execute in a given order. It’s called “imperative” because as programmers we dictate exactly what the computer has to do, in a very specific way. When it comes to writing good code, you can dive into highly philosophical discussions about what exactly good code looks like and which programming paradigm you should follow.

Functional Programming

Procedural programming languages are also imperative languages, because they make explicit references to the state of the execution environment. This could be anything from variables to something like the position of the “turtle” in the Logo programming language. OOPs, provide the ability to simulate real-world events much more effectively. We can provide the solution to real-world problems if we are using the Object-Oriented Programming language. OOPs, provide data hiding, whereas, in Procedure-oriented programming language, global data can be accessed from anywhere. During the program’s execution, a procedure can be called at any point, either by other procedures or by itself.
