    Learn about Dennis Ritchie, the co-inventor of UNIX and the developer of C, two foundations of modern computing. He received many awards, including the Turing Award and the National Medal of Technology, and worked at Bell Labs for four decades.

  2. 5 days ago · C Programming at Wikibooks. C ( pronounced / ˈsiː / – like the letter c) [6] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs.

  3. 2 days ago · The C language developed by Dennis Ritchie in 1972. In 1970, Ken Thompson built upon BCPL to create a typeless language called B. Subsequently, Dennis Ritchie at AT&T Bell Labs took charge of the C language’s development in 1972, drawing inspiration from the foundations laid by BCPL and B.

  4. Jun 10, 2024 · C is a middle-level programming language developed by Dennis Ritchie during the early 1970s while working at AT&T Bell Labs in the USA. The objective of its development was in the context of the re-design of the UNIX operating system to enable it to be used on multiple computers.

  5. 1 day ago · C was developed at Bell Labs by Dennis Ritchie, initially outlined between 1972 to 1973. The primary purpose was to rewrite the UNIX operating system, initially written in assembly language, into a high-level language that could still directly access low-level hardware modules. Thus came the birth of C, leading to UNIX becoming one of the first ...

  6. Jun 20, 2024 · In 1969 a team led by computer scientists Ken Thompson and Dennis Ritchie created the first version of UNIX on a PDP-7 minicomputer, which was chosen mainly because of Thompson’s familiarity with the system from his hobby work on it.
