Introduction

C++ is a general-purpose object-oriented programming (OOP) language , developed by Bjarne Stroustrup in 1979 at Bell Labs in Murray Hill, New Jersey. It provides the facilities of Encapsulation, Inheritance, Abstractions, Data hiding, polymorphism etc.It is one of the most popular languages which is used to develop system or application software, drivers, client-server applications and embedded firmware.

              C++ is considered as an intermediate-level language because it supports both high- level and low-level language features. Initially, the language was called "C with classes" as it had all the properties of the C language with an additional concept of "classes." However, it was renamed C++ in 1983. It is pronounced "see-plus-plus."


C++ is an extension of the C language, therefore it possible to develop program in two ways:-
1)In a C style
2)In object-oriented style


In certain scenarios, it can be coded in either way and in hybrid way. The main highlight of C++ is a collection of predefined classes, which are data types that can be instantiated multiple times. The language also facilitates declaration of user-defined classes. Classes can further accommodate member functions to implement specific functionality. Multiple objects of a particular class can be defined to implement the functions within the class. Objects can be defined as instances created at run time. These classes can also be inherited by other new classes which take in the public and protected functionalities by default.

C++ includes several operators such as comparison, arithmetic, bit manipulation and logical operators. One of the most attractive features of C++ is that it enables the overloading of certain operators such as addition. A few of the essential concepts within the C++ programming language include polymorphism, virtual and friend functions, templates, namespaces and pointers.

Real-World Applications of C++

1. Games:

C++ overrides the complexities of 3D games, optimizes resource management and facilitates multiplayer with networking. The language is extremely fast, allows procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines. For instance, the science fiction game Doom 3 is cited as an example of a game that used C++ well and the Unreal Engine, a suite of game development tools, is written in C++.

2. Graphic User Interface (GUI) based applications:

Many highly used applications, such as Image Ready, Adobe Premier, Photoshop and Illustrator, are scripted in C++.

3. Web Browsers:

With the introduction of specialized languages such as PHP and Java, the adoption of C++ is limited for scripting of websites and web applications. However, where speed and reliability are required, C++ is still preferred. For instance, a part of Google's back-end is coded in C++, and the rendering engine of a few open source projects, such as web browser Mozilla Firefox and email client Mozilla Thunderbird, are also scripted in the programming language.

4. Advance Computations and Graphics:

C++ provides the means for building applications requiring real-time physical simulations, high-performance image processing, and mobile sensor applications. Maya 3D software, used for integrated 3D modeling, visual effects and animation, is coded in C++.

Database Software:

C++ and C have been used for scripting MySQL, one of the most popular database management software. The software forms the backbone of a variety of database-based enterprises, such as Google, Wikipedia, Yahoo and YouTube etc.

6. Operating Systems:

C++ forms an integral part of many of the prevalent operating systems including Apple's OS X and various versions of Microsoft Windows, and the erstwhile Symbian mobile OS.

7.Enterprise Software:

C++ finds a purpose in banking and trading enterprise applications, such as those deployed by Bloomberg and Reuters. It is also used in development of advanced software, such as flight simulators and radar processing

8.Compilers:

A host of compilers including Apple C++, Bloodshed Dev-C++, Clang C++ and MINGW make use of C++ language.

Advantages of C++

1)C++ is a highly portable language and is often the language of choice for multi-device, multi-platform app development.

2)C++ is an object-oriented programming language and includes classes, inheritance, polymorphism, data abstraction and encapsulation.

3)C++ has a rich function library.

4)C++ allows exception handling, and function overloading which are not possible in C.

5)C++ is a powerful, efficient and fast language. It finds a wide range of applications from GUI applications to 3D graphics for games to real-time mathematical simulations.

How to Learn C++ Programming

Learning C++ programming definitely isn't an overnight thing.It will takes some time and need a large amount of hard work and dedication.Follow the steps to learn c++ :-

1)Learn about Fundamental & history of C++ .

2)Then install a C++ compiler and possible IDE such as Turbo c,Bloodshed Dev-C++ IDE and compiler etc.

3)Then Learn how to use your IDE efficiently.

4)Then Select Your Guide and Tutorials such as "www.prinfohub.in".

5)Learn from other developers.

6)Work through problems using the concepts you have learned.

7)Help others who need help.

Now that you have learned about C++, you should start helping other newbies online with their problems and get them started on the same journey you had! Don't get frustrated if the person who asked you for help doesn't want to listen to your advice: someone else could learn from the answer you provide even if the original poster didn't.
