Difference between Objective-C and Virtual function

Objective-C vs. Virtual function

Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. In object-oriented programming such as is often used in C++ and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically.

C++

C++ (pronounced "C plus plus" and sometimes abbreviated as CPP) is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup.

Class (computer programming)

In object-oriented programming, a class defines the shared aspects of objects created from the class.

Dynamic dispatch

In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time.

Execution (computing)

Execution in computer and software engineering is the process by which a computer or virtual machine interprets and acts on the instructions of a computer program.

Interface (object-oriented programming)

In object-oriented programming, an interface or protocol type is a data type that acts as an abstraction of a class.

Java (programming language)

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.

Method (computer programming)

A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message.

Multiple inheritance

Multiple inheritance is a feature of some object-oriented computer programming languages in which an object or class can inherit features from more than one parent object or parent class.

Object-oriented programming

Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

Pointer (computer programming)

In computer science, a pointer is an object in many programming languages that stores a memory address.

Polymorphism (computer science)

In programming language theory and type theory, polymorphism is the use of a single symbol to represent multiple different types.

Runtime system

In computer programming, a runtime system or runtime environment is a sub-system that exists both in the computer where a program is created, as well as in the computers where the program is intended to be run.

Software design pattern

In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code.
