Introduction to C++ Programming language

Definition of C++

C++ is a case-sensitive, general purpose, and a free-form programming language that supports procedural, object-oriented, and generic programming. As it encapsulates both high and low-level language features, C++ is a middle-level language. A lot of platform like Windows, Linux, Unix, Mac, etc. supports C++ programming language.

Benefits of C++  Over C Language

1.   In C++, Stronger Type Checking is available.
2.  The OOPS features in C++ like Abstraction, Encapsulation, Inheritance, etc make it more worthy and useful for programmers.
3. C++ supports and allows user-defined operators (i.e Operator Overloading) and function overloading.
4.   The Concept of Virtual functions and also Constructors and Destructors for Objects.
5.  There is Exception Handling in C++.
6.  In C++ variable can be declared anywhere in the program, but must be declared before they are used.

History of C++ Programming Language

Bjarne Stroustrup developed C++ programming language in 1980 by at bell laboratories of AT&T (American Telephone & Telegraph), located in the U.S.A.
The founder of C++ language is Bjarne Stroustrup.
It is developed for adding a feature of Object Oriented Programming (OOP) in C without significantly changing the C component.
C++ programming is relatively called a superset of C, it means any valid C program is also a valid C++ program.

Usage of C++ Programming Language

There are several benefits of using C++ for developing applications and many applications product based developed in this language only due to its features and security. Below is the usage areas of C++  where it has been widely and effectively used.

1.Application

It is used in the development of new applications of C++. The applications based on the graphic user interface, which are highly used applications like adobe photoshop and others.

2.Operating System

It is also used for developing most of the operating systems for Microsoft and a few parts of the Apple operating system. Microsoft Windows 95, 98, 2000, XP, office, Internet Explorer and visual studio, Symbian mobile operating systems are mainly written in C++ language only.

3.Web browsers

The rendering engines of various web browsers are programmed in C++ simply because if the speed that it offers. The rendering engines require faster execution to make sure that users don’t have to wait for the content to come up on the screen. As a result, such low-latency systems employ C++ as the programming language.

4.Games

The C++ language is also used for developing games. It overrides the complexity of 3D games. It helps to optimize the resources. It supports multiplayer option with networking. Uses of C++ allows procedural programming for intensive functions of CPU and to provide control over hardware, and this language is very fast due to which it is widely used in developing different games or in gaming engines. C++ is mainly used in developing the suites of a game tool.

5.Databases

Postgres and MySQL– two of the most widely used databases are written in C++ and C, the precursor to C++. These databases are used in almost all of the well-known applications that we all use in our day to day life – Quora, YouTube, etc.

6.Compilers

The compilers of various programming languages use C and C++ as the backend programming language. This is due to the fact that both C and C++ are relatively lower level languages and are closer to the hardware and therefore are the ideal choice for such compilation systems.
