According to Dennis Ritchie, people often assumed that they were created for the auto-increment and auto-decrement address modes of the DEC PDP-11, but this is historically impossible as the machine didn't exist when B was first developed. The B was designed for recursive, non-numeric, machine-independent applications, such as system and language software. Manage Existing Subscriptions During 1971 and 1972 B evolved into "New B" (NB) and then C.[2]. */, "Its name most probably represents a contraction of BCPL, though an alternate theory holds that it derives from Bon [Thompson 69], an unrelated language created by Thompson during the Multics days. However, the word is sometimes used to describe your friends or lovers and even to reply back to a compliment. The earliest PDP-7 implementations compiled to threaded code, and Ritchie wrote a compiler using TMG which produced machine code. [2][9], The typeless nature of B made sense on the Honeywell, PDP-7 and many older computers, but was a problem on the PDP-11 because it was difficult to elegantly access the character data type that the PDP-11 and most modern computers fully support. Examples might be simplified to improve reading and learning. B is a programming language developed at Bell Labs circa 1969. The following examples are from the Users' Reference to B by Ken Thompson:[3], This article is about a language developed at Bell Labs. be denoted with the Thompson's coworker Dennis Ritchie speculated that the name might be based on Bon, an earlier, but unrelated, programming language that Thompson designed for use on Multics.

It is the work of Ken Thompson with Dennis Ritchie. specification states that headings should be denoted with the For "b" language of Meertens and Pemberton, see, /* The following function will print a non-negative number, n, to, the base b, where 2<=b<=10. [10] However, it continues to see use on GCOS mainframes (as of 2014[update])[11] Unforgettable trips start with Airbnb. The BCPL to B transition also included changes made to suit Thompson's preferences (mostly along the lines of reducing the number of non-whitespace characters in a typical program). The typeless nature of the language was seen as a disadvantage, which led Thompson and Ritchie to develop an expanded version of the language supporting new internal and user-defined types, which became the C programming language.
