C

C is a general-purpose, imperative programming language developed by Dennis Ritchie at Bell Labs in the early 1970s to build the Unix operating system. It gives low-level access to memory and maps efficiently to machine instructions, which makes it fast and portable across nearly every platform. C also shaped a whole family of later languages, including C++, C#, Objective-C, Java, and Swift, which share much of its syntax and style.
