The C Language is currently one of the most widely used programming languages in the world. Designed as a tool for creating operating systems (the first Unix systems were constructed with its help), it quickly proved that it is suitable wherever you need high performance, speed, compactness and portability. Even though shortly after its release it was followed by a worthy descendant, the C + + language, it did not lose its importance, and it remains an essential tool for developers and designers in many applications.
Whenever a code strongly associated with the operation of equipment is created, the C language proves its flexibility and adaptability. Network card drivers, graphics card software, operating systems and micro-controllers – these things can be found all around you, on your desk and in your car, in the kitchen and in the garage, simply everywhere intelligent electronics functions – you are sure to find the work of programmers who write in “C”. The heart of Linux is nearly 15 million lines of code in “C”. There is no better evidence for the language’s longevity.
Even in places where modern software with much more powerful abilities works, the C language was, is and will be present, because it is the language in which run-times (run-time environments) are written, responsible for performance, economical memory usage and reliability. The “C” language niche extends from single-chip microcomputers controlling your coffee machine, to your laptop onto which you have just installed the latest graphics card drivers, to supercomputers that forecast the weather for your desired holiday.
