C is a procedural programming language. It was initially designed by Dennis Ritchie in the year 1972. It was mainly developed as being a system programming language to write an operating-system. The main highlights of C language include low-level access to memory, a basic set of keywords, and clean style, these characteristics make C language ideal for system programmings like an operating-system or compiler development.
Lots of the C projects which exist today were started decades ago.
The UNIX operating system’s development began in 1969, and its code was rewritten in C in 1972. The C language was really created to move the UNIX kernel code from assembly to your higher level language, which will perform the same tasks with fewer lines of code.
Oracle database development began in 1977, and its code was rewritten from assembly to C in 1983. It became just about the most popular databases in the world.
In 1985 Windows 1. was introduced. Although Windows source code is not really publicly available, it’s been stated that its kernel is mainly written in C, with many parts in assembly. Linux kernel development began in 1991, which is also developed in C. Another year, it absolutely was released under the GNU license and was applied within the GNU Operating System. The GNU operating-system itself was started using C and Lisp programming languages, lots of its components are written in C.
But C programming isn’t limited to projects that started decades ago, when there weren’t as much programming languages as today. Many C projects remain started today; there are several good reasons for that.
How is the World Powered by C? Despite the prevalence of higher-level languages, C consistently empower the entire world. The subsequent are the systems which are employed by millions and they are programmed in the C language.
Microsoft Windows – Microsoft’s Windows kernel is developed mostly in C, with a few parts in assembly language. For years, the world’s most used operating system, with about 90 percent from the market share, has become powered by way of a kernel printed in C.
Linux – Linux is additionally written mostly in C, with many parts in assembly. About 97 percent from the world’s 500 most powerful supercomputers run the Linux kernel. It is also used in many computers.
Mac – Mac computers are also powered by C, because the OS X kernel is written mostly in C. Every program and driver in a Mac, as in Windows and Linux computers, is running on the C-powered kernel.
Mobile – iOS, Android and Windows Phone kernels can also be printed in C. They may be just mobile adaptations of existing Mac OS, Linux and Windows kernels. So smartphones you make use of every day are running on a C kernel.
The world’s most popular databases, including Oracle Database, MySQL, MS SQL Server, and PostgreSQL, are coded in C (the initial three of those actually in C and C ). Databases are employed in every kind of systems: financial, government, media, entertainment, telecommunications, health, education, retail, social networks, web, and the like.
3D movies are made with applications that are generally written in C and C . Those applications need to be very efficient and fast, since they handle a huge amount of data and do many calculations per second. The greater efficient unscon are, the less time it will take for that artists and animators to generate the movie shots, and also the more cash the company saves.
Embedded Systems – Imagine that you wake up one day and go shopping. The alarm clock that wakes you up is likely programmed in C. Then you certainly make use of microwave or coffee maker to make your breakfast. They are also embedded systems and they are probably programmed in C. You switch on your TV or radio as you eat your breakfast. Those will also be embedded systems, powered by C. When you open your garage door using the remote control you might be also employing an embedded system that is probably programmed in C.
