Demystifying C++: A Dive into High-Performance Programming

What Is C++? 

C++ is an object-oriented, generic programming language used to build software. It uses data fields with unique attributes (referred to as objects) instead of logic or functions. Objects refer to things like user accounts on a website, for example. This information includes data like a person’s name, email address and phone number. When you bundle this information together to create an object, it’s easy to replicate that information later on if you need to do so. 

When C++ was first designed, it was meant to be used for large systems and resource-constrained software but it has expanded over time. The latest version of C++ goes beyond object features to include functional and generic features as well, in addition to features for low-level memory manipulation. One of the biggest advantages of C++ is that it is very easy to scale, and it lets developers control how their applications use resources. 


What Is C++ Used For Professionally? 

C++ is the go-to language when developers need to build fast, reliable software because it is incredibly versatile and a great pick for more complex applications, embedded systems and also IoT (internet of things) devices. If building this software is beyond your possibilities, you can always contact our team to help you out. Let’s take a look at some of its main uses: 

  • Software Engineering. If you use apps on your smartphone or other devices, chances are you have run into ones created with C++. These include streaming services like Netflix, for example. 

  • OS Development. C++ was used to create Microsoft Windows, Mac OS X and iOS, meaning the most common operating systems in use today were crafted with this programming language. 

  • VR. Virtual reality uses C++ in a majority of its applications. 

  • Blockchain Technology. Bitcoin, probably the most well-known cryptocurrency, was developed using C++. 

  • Gaming. Games and consoles can be developed with C++. Lots of gaming companies use it as their main language for developing their apps and systems because it easily manipulates resources and can handle tougher 3D games and multiplayer networks easily. 

  • Web Browsers. Most browsers use C++ for rendering because they need to be super fast and responsive. Browsers like Mozilla Firefox are completely developed using C++ and Google apps like Chrome and Google’s file system are also partially written in C++.

  • Digital Banking. C++ is a go-to for banking applications because they require concurrency, multi-threading and high-performance across their interfaces. 

  • Cloud Systems. Large cloud storage systems work close to the hardware and require things like multithreading support, all of which makes C++ the perfect choice for implementing and maintaining them. 

There are other uses for C++, including compilers and embedded systems, but these are some of the main and most common examples of what this programming language is used for — and where you’re likely to have come across it in your day to day life.


C++: Concepts And How-to

Learning C++ doesn’t have to be complicated. Some of the basics include storing information, repeating different tasks through loops and collecting data from users. Let’s take a look at some of the basic concepts for C++ that you should keep in mind if you’re looking to explore this programming language. 

  • C++ Variables. Variables are the foundation of every programming language. They refer to one of the ways in which you can store information that you’ll need to use later. You can retrieve this data later by referring to a word that describes it, and once you’ve defined this you can repeat this action multiple times. 

  • C++ Control Structures. Code flow, or the way the code is read by a compiler (top to bottom and generally left to right) happens when a program runs. Sometimes, the program may need to jump to a different part of the code which could mean that it needs to re-run a specific piece of the code again or skip ahead to something else. Control structures are the rules that help decide and control program execution flow. 

  • C++ Data Structures. This refers to how information is stored and organized within the world of programming. Storing information using data structures is useful because it allows you to easily manipulate large amounts of text and it gives you the flexibility you need when you’re working with literally thousands of variables. C++ language contains several types of inbuilt data structures, including arrays. 

  • C++ Syntax. Syntax, much like its grammatical definition, refers to the layout of words, expressions and symbols in code. The combination of all of these elements gives you a specific, desired output that you need to create software that works correctly. You’ll need to follow the necessary set of rules to make sure that you don’t get errors in your code. 

  • C++ Tools. Programming tools let you work faster and more efficiently when you’re coding, and there is an endless amount available across various programming languages. One of the most well-known and more widely used is IDE, an Integrated Development Environment. This makes sure that your files and folders stay organized and keep the interface nice and neat. 

C++ is a popular programming language that offers several advantages and almost limitless possibilities for your coding experience. If you have never used it before, you have run across it in at least one application that you use on a daily basis. 

Learning more about C++ is easy thanks to the wide array of online courses and information available, some of which is free to use. C++ is a great choice whether you want to further your software developer career, grow professionally or simply want to learn more about one of the most widely used programming languages out there.
