C++ Tutorial

C++ Introduction

C++ is an object-oriented programming language. It was developed by Bjarne Stroustrup at AT&T Bell Laboratories. It is superset (extension) of C programming language.

Depending upon features supported by programming languages, they are classified into two different categories:

Object-based programming languages
Object-oriented programming languages

Object-based programming language

The language that supports programming using objects is called object-based programming language. Important features of object-based programming languages are:

Data encapsulation
Data hiding
Operator overloading
Automatic initialization

Object-oriented programming language

Object-oriented programming supports the features of object-based programming along with inheritance and dynamic binding.

C++ fully supports object-oriented programming. To understand Object-Oriented programming, we need to know the concept of a major pillar of it:

Object
Class
Data abstraction
Encapsulation
Polymorphism
Inheritance
Dynamic binding
Message passing

C++ is not a pure object-oriented language. Object-oriented means working with object and class, but in C++ program can be written without using class.

C++ Usages

C++ program is applied in a large number of different sector. Some of them are as follow:

Windows System
Real-time system
Object-oriented database
Artificial Intelligence
Device driver etc.

C++ Example

We have given online editor option with each C++ example. So, you can edit any example and see the changed output.

#include <iostream>    
using namespace std;    
int main() {    
   cout << "Hello C++ by TutorialAndExample";    
   return 0;    
}
