Why and where should you still use C/C++ languages?

From complex databases to self-driving cars, the usage area of C and C++ languages is surprisingly wide. Even today, with a myriad of new & robust programming tools, the two coding languages from 70s cannot be replaced. So what are the common applications of C & C++ today and why we still use them? Let’s find out in this article. When is C language used? What is C++ used for? 1. Operating systems Since C language was originally designed for system level programming, it’s no surprise that it’s commonly used to build operating systems and firmware. It’s close enough to the hardware layer to manipulate low-level code but also fast and energy-efficient. These factors make it a perfect fit for OS development. Above all, any operating system has to run fast and efficiently manage system resources. For example, are all written in C. As well as Android and iOS to some extent. Linux, Microsoft Windows, Mac OS A C developer can implement all the data structures himself, fine-tuning the smallest details of an operating system. Such increased flexibility makes C a commonly preferred option. And unlike other languages, C has no runtime dependencies. This means that a program could run directly on the hardware without requiring a memory manager, input or output layer. 2. Embedded systems programming C is the de-facto language when it comes to embedded systems engineering. Why so? C language consumes very few memory resources which makes the program run quickly. As a result, you can expect the embedded systems to perform in real time with no overhead. Mainly due to its’ high performance and ease of use. So you can compile an embedded program across various devices and platforms with little or no change at all. More so, since C code is highly portable, it is not tied to any specific microprocessor or a system. That’s why autonomous cars, smartwatches, IoT sensors and devices like coffee machines have firmware all written in C or C++. In connected systems, C lets you work directly with the memory resources and adjust every part of the code. So if you're choosing the right technology for your , consider these languages. IoT development project 3. Game & game engine development The performance is critical for a game, so the choice of a programming language is limited in this field. Since C++ is the fastest programming language for today, it turns out one of the best choices for 3D, multiplayer or other games. For instance, Counter-Strike, StarCraft: Brood War, Diablo I, World of Warcraft are all written in C++. Not to mention Xbox and PlayStation consoles which are based on C++ programming. The core of Unity game engine also used C++ development. And Unity is the most popular engine for building video games, targetting multiple OS at once. Even the most intensive game graphics can be handled with C++ software development. It lets you optimize and adjust how exactly the game memory resources and data structures will be used. As a result, you have complete control over the game development. 4. Desktop & cross-platform app development C++ can be also used to build desktop applications. All thanks to its’ superior cross-platform frameworks such as Qt. It allows you to target Windows, Linux, macOS, Android and embedded systems — all with a single codebase. So the app development with Qt turns out a great option if you want to cut the programming time & costs. Another feature-rich library SDL lets you build for Windows, Linux, Android, MacOS and iOS at the same time. By the way, Photoshop, Illustrator and Adobe Premiere are all written in C++. What are some other applications? to reduce the power consumption per user. Cloud storage systems, databases, device drivers and other types of software might use C++ development. Facebook converted some of its code from PHP to C++ language Consider also banking and other apps with high concurrency and low latency support. Or basically, anything that has to run fast with no issues. Summary Taking into account all of the above, we consider C/C++ languages good choices for: OS development Embedded systems programming Game development Database development Desktop & (using C++ framework). cross-platform development For example, in projects dealing with complex data types, software development with C++ prevents data overload or related issues. So if you’re asking: Why we still use C/C++? Here’s the short answer: C and C++ are flexible, extremely fast and efficient. And they are closer to machine code than any other language. That’s why, in some cases, these languages simply cannot be replaced. In fact, C is the second language by popularity as it closely follows Java according to Tiobe. Here’s our prediction: In the near future, C language will not leave the tech arena. Especially since the number of IoT connected devices is growing, and they heavily rely on the machine code and memory manipulation. Are you excited to see what’s coming?
