TIOBE's September 2020 computer Community index says that C++ is the computer language that is growing the fastest. Bjarne Stroustrup made C++ in 1979 as an extension of the C language. It is an object-oriented, general-purpose computer language.
Even though it's been around for almost 40 years, C++ is still the language that programmers and writers prefer. This article will discuss what makes C++ so popular, how it can be used in real life, and how to get a job in the area this article covers.
Simple things that will help you understand C++ better can be found in the movie below.
How do you program in C++?
Bjarne Stroustrup made C++ in 1979 as part of his Ph.D. project. It is an improved and expanded version of the computer language C. Bjarne made what he called "C with Classes" (later changed to C++) because he didn't like how the existing computer languages weren't good for big projects. He build what he wanted with C because it was already a general-purpose language that worked quickly and well.
C++ is a powerful, flexible, and all-purpose computer language. The free-form, statically-typed, multi-paradigm, and usually compiled computer language works best for programmers with some experience. If you want to start programming, though, you can learn the basics of C++ very quickly. These skills will help you a lot as you go through your job.
Why has C++ stayed popular and grown over the years?
You can find C++ almost anywhere. The language is used by about 4.4 million coders around the world. C++ code is used to power a lot of current systems, such as search engines, VR apps, databases, operating systems, web browsers, and even movies. C++ is used to make Adobe goods, Unreal Engine, and the Chrome and Firefox browsers. Because it is fast, it is often chosen in places where performance is important. Also, the most recent version of the C++20 standard has made it the language that developers use the most.
C++ is still a useful and popular language, so it's still worth learning in 2021. There are a lot of job openings in C++ in many fields, such as finance, application development, game development, virtual reality, and more.
Many people use C++ to build large software systems and programs that only need a small amount of resources. C++ is the only programming language that can directly change the hardware it runs on. So, programmers can change their code so that an app works well in any setting, even if the hardware doesn't have a lot of room or power. These kinds of C++ programs work quickly and well on a variety of devices, which makes C++ the best choice for many important tasks.
History and Background of C++
The first version of C++ came out in 1985, but it wasn't until 1998 that the first approved version, called C++98, came out. According to the next standard, C++03, which came out in 2003, its main goal was to fix bugs found in C++98 and make the language more consistent and portable.
Eight years later, in 2011, the next big change to the language came out. It was called C++11. After that, C++14 came out and fixed bugs and made some small changes to C++11 before the next big release, C++17. The new version of C++17 has a lot more standard libraries and a few new features. Since each version happens every three years, the next one will come out in 2020 and be called C++20.

Pros of using C++
It's too long for this piece to list all of the great things about C++ because it's such a strong programming language. If you are just starting out, though, here are some of the good things about it:
Speed up. Higher-level languages like Java and Python take a lot longer to run than low-level languages. Given that C++ is an expanded type of the low-level computer language C, it is one of the fastest programming languages out there.
How well it works. There is a standard template library (STL) in C++ that can be used a lot when writing code. Because these libraries contain efficient algorithms, the coder can save time and effort that would have been used to write code.
Having the freedom to pick out how to program. C++ is a multi-paradigm computer language because it can be used with about seven different ways of writing code. This means you don't have to use objects to choose a style that works for you.
Being able to break down big problems into smaller ones. C++ is partly an object-oriented computer language, which means that making objects can help you solve hard problems in a natural way. Besides that, C++ functions let you divide code into logical blocks that are clear, simple, and simple to test and change.
The ability to find and fix mistakes before they run. It is statically typed in C++, which means the compiler doesn't guess what the programmer writes. Bugs and mistakes can be found by the program before they are run, which can save time in the long run.
Practical Applications of C++
This part talks about the seven most common ways that C++ is used.
Systems for running
C++ was used to make most operating systems, such as Microsoft Windows, Apple Mac OS X, Symbian OS, and even mobile operating systems like IOS. Most of the time, operating systems need to be quick and good at using system resources. When you need to write an operating system, C++ is the best language for the job because it is fast and has many system-level methods.
The need to study distributed applications of the UNIX Operating System led to the creation of C++. The UNIX Operating System was the first OS to be built with a computer language like C.
Playing games
This is one of the main reasons why C++ is so popular in game development: it works well with hardware. C++ and its speed are used in games where images are an important part of the play. For multiplayer sessions to work, gaming needs a lot of features that use a lot of resources. C++ can make the best use of resources, support networking for multiple players, and handle the complexity of 3D games.
C++ was used to make well-known games like Counter-Strike and World of Warcraft, as well as game engines like Unreal Engine and gaming devices like the Xbox, PlayStation, and Nintendo Switch.
Applications with a GUI
The speed of C++ makes it a good choice for making many popular PC and GUI (Graphical User Interface) apps. Applications for Adobe systems like Illustrator, Photoshop, and Microsoft's Win Amp Media Player are all examples of this. They were all made with C++.
Browsers for the web
It's likely that your present web browser was made in C++. It runs the server services that get data from databases and turn code into web pages that you can interact with. Browsers can work quickly and with little delay when they use C++, so information doesn't take long to show up on our screens.
Many of the most famous web browsers we use today were made with C++.
The Internet Explorer
Chrome Google
Firefox by Mozilla
A Safari
The Netscape Navigator
The Opera
System for managing databases
C++ was used to make well-known database management tools like MySQL, Oracle, Postgres, and MongoDB. More than any other open-source database, MySQL is used by most businesses. These libraries are an important part of big apps made by companies like Adobe, Google, Netflix, and YouTube. C++ is great for managing data because it can handle files, is fast, reliable, and has functions, classes, and objects.
Cloud computing and applications that run on many computers
C++ is a language that is very close to the hardware, so it is naturally chosen for building cloud storage systems. It works with a lot of tools. So, big businesses that use cloud computing and spread applications use C++ because it supports multiple threads, which lets them build applications that run at the same time, and it can handle a lot of traffic on the hardware system.
Bloomberg is a distributed RDBMS application that gives investors correct news and information about the stock market in real time. Bloomberg's development environment and tools were written in C++.
Libraries
There are many built-in functions in the standard library of C++. When you do high-level math, performance and speed become important. Because of this, C++ is the main computer language used by most libraries. C++ is a great choice for a backend programming language because it has libraries for a lot of new and famous high-level libraries, such as Machine language libraries.
As an example, the Brain Team at Google made TensorFlow, a powerful, open-source machine learning library. It was built with C++ apps in the background.
In conclusion
Now that you know how to use a lot of different types of C++ programs, read about the career opportunities that we talked about in this piece. This will help you get started on the right path.
