During the 1970s, while at Bell Labs, along with developing Unix(the base for modern day Linux*), Dennis Ritchie created the programming language C, based off of B, made by Ken Thompson, in order to be used with Unix. The language is quite simple and easy to learn(unlike some languages that are based off of it), and it is considered low level and manual memory management is required. Many languages are based off of C or inspired by it, shuch as C++, C#, D, Go, Java, JavaScript, Objective-C, Perl, PHP, Python, Ruby, Rust, and Swift.
