What is protocol-oriented programming?

Protocol-Oriented Programming is a new programming paradigm ushered in by Swift 2.0. In the Protocol-Oriented approach, we start designing our system by defining protocols. We rely on new concepts: protocol extensions, protocol inheritance, and protocol compositions. In Swift, value types are preferred over classes.

What is the difference between object oriented programming and functional programming?

In functional programming, data cannot be stored in objects and it can only be transformed by creating functions. In object-oriented programming, data is stored in objects. In functional programming, it requires always a new object to execute functions and it takes a lot of memory for executing the applications.

What is the difference between oops and pops?

The key difference between OOP and POP is that an OOP divides a program into smaller objects, whereas POP divides a program into smaller procedures or functions to arrive at the results of the problem.

What is the difference between object and function?

An object is a collection of functions and data. A function is a collection of commands and data. When a bunch of functions work together to perform a certain task we may call this community of functionality an object.

Why is oops used?

Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

What is difference between protocol and delegate?

We can say Protocol as a set of rules. That rules can be optional or required like we have to use in protocol. Delegates is a message passing technique in objective C and swift. An object has to take care of that message.

What is object-oriented programming (OOP)?

Object-oriented Programming is a programming language that uses classes and objects to create models based on the real world environment. In OOPs it makes it easy to maintain and modify existing code as new objects are created inheriting characteristics from existing ones.

What is the difference between procedural programming and object oriented programming?

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

What is the difference between object oriented languages and object based languages?

Object Based languages are different from Object Oriented Languages: Object Based Languages Object based languages supports the usage of object and encapsulation. They does not support inheritance or, polymorphism or, both. Object based languages does not supports built-in objects. Javascript, VB are the examples of object bases languages.

What are the different types of programming languages?

Java, C++, C#, Python, PHP, JavaScript, Ruby, Perl, Objective-C, Dart, Swift, Scala. In procedural programming, program is divided into small parts called functions. In object oriented programming, program is divided into small parts called objects.
