1.1 Brief History of C

An Overview of C>>Brief History of C


C was invented and first implemented by Dennis Ritchie on a DEC PDP- 11 that used the UNIX operating system. C is the result of a development process that started with an older language called BCPL. BCPL was developed by Martin Richards, and it influenced a language called B, which was invented by Ken Thompson. B led to the development of C in the 1970s.


The ANSI C standard was finally adopted in December 1989, with the first copies becoming available in early 1990. The standard was also adopted by ISO (International Standards Organization), and the resulting standard was typically referred to as ANSI/ISO Standard C. The end result was the 1999 standard for C, usually referred to as C99. In general, C99 retained nearly all of the features of C89. Thus, C is still C!.
