Why do we use C language?

C language was initially used for systemdevelopment work in particular the programs that make-up theoperating system. C was adopted as a system developmentlanguage because it produces code that runs nearly as fastas code written in assembly language. Today C is themost widely used System ProgrammingLanguage.
