What was the original purpose of developing the C language?

The C programming language was originally developed for and implemented as the system programming language for the Unix operating system. It was created by Dennis Ritchie at Bell Labs between 1972 and 1973. The main purpose was to provide a more efficient and flexible way to write operating system code. Before C, the Unix operating system was written in assembly language, which was difficult to understand, modify, and port to different computer architectures. C provided a higher-level language that was closer to human language, which made the code easier to understand, modify, and port. It also provided direct access to memory and low-level hardware operations, which made it possible to write efficient code that ran as fast as assembly language code.
