History. BCPL was first implemented by Martin Richards of the University of Cambridge in 1967. [1] BCPL was a response to difficulties with its predecessor, Cambridge Programming Language, later renamed Combined Programming Language (CPL), which was designed during the early 1960s.
23 maj 2024 · Early C. 1969: B created, based on BCPL, to replace PDP-7 assembler as the system programming language for Unix. added operators ++, --, compound assignment, remained a typeless language like BCPL. 1971: NB ("new B") created when porting B to PDP-11.
The C programming language was devised in the early 1970s as a system implementation language for the nascent Unix operating system. Derived from the typeless language BCPL, it evolved a type structure; created on a tiny machine as a tool to improve a meager programming environment, it has become one of the dominant languages of today.
This paper describes how the programming language BCPL developed from the work on the design and implementation of CPL. It shows that BCPL is essentially just CPL with all the difficult bits removed and with just a few extensions. The CPL project lasted from early 1962 to December 1966 and the first outline of BCPL appeared in 1966.
2 lut 2024 · History of C language - Dennis Ritchie developed C using BCPL and B as its predecessors. The goal was to create a language that would provide low-level memory access while still offering high-level abstractions for system programming.
In 1967, Martin Richards developed a language called BCPL (Basic Combined Programming Language). BCPL was derived from ALGOL. In 1970, Ken Thompson created a language using BCPL called B.
