C was created by Dennis Ritchie at Bell Labs in the early 1970s as an augmented version of Ken Thompson's B. [3] Another Bell Labs employee, Brian Kernighan, had written the first C tutorial, [4] and he persuaded Ritchie to coauthor a book on the language. [5]
A successor to the programming language B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. [9] During the 1980s, C gradually gained popularity.
Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...
The Portable C Compiler (also known as pcc or sometimes pccm - portable C compiler machine) is an early compiler for the C programming language written by Stephen C. Johnson of Bell Labs in the mid-1970s, [1] based in part on ideas proposed by Alan Snyder in 1973, [2] [3] and "distributed as the C compiler by Bell Labs... with the blessing of Dennis Ritchie."
Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. [3] He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson. [3]
Feedback from Thompson's Unix development was also instrumental in the development of the C programming language. Thompson would later say that the C language "grew up with one of the rewritings of the system and, as such, it became perfect for writing systems". [18] In 1975, Thompson took a sabbatical from Bell Labs and went to his alma mater ...
He worked at Bell Labs and contributed to the development of Unix alongside Unix creators Ken Thompson and Dennis Ritchie. Kernighan's name became widely known through co-authorship of the first book on the C programming language (The C Programming Language) with Dennis Ritchie. Kernighan affirmed that he had no part in the design of the C ...
Was the head of Bell Labs Large-scale Programming Research department, from its creation until late 2002 and created the C++ programming language. Brian Kernighan Helped to create Unix , AWK , AMPL and authored along with Dennis Ritchie influential The C Programming Language book.
