The C language is mother and grandmother of a whole range of modern languages, like C++, PHP, C#, Java, Objective C, Swift, JavaScript and others. Development of the language is continuing, and the latest version, from December of 2011, is called C11. C is still in heavy use, mostly for embedded systems, realtime applications and operating systems on small devices.
