Dennis Ritchie and Ken Thompson are the two computer scientists who developed the C language. They were both employees of Bell Labs. They started working on the language, and they wanted to create a system that would allow programmers to write machine-independent programs. It was originally designed to be a system programming language, but it is now widely used in many applications. The language has been revised and extended over time and is now used to write large-scale applications that are not limited to system programming. As a result, the C programming language is one of the oldest high-level languages in use today. It was first introduced by Dennis Ritchie and Ken Thompson in the 1970s.
