C 23
C++23, formally ISO/IEC 14882:2024, is the current open standard for the C++ programming language that follows C++20. The final draft of this version is N4950. In February 2020, at the final meeting for C++20 in Prague, an overall plan for C++23 was adopted: planned features for C++23 were library support for coroutines, a modular standard library, executors, and networking. The first WG21 meeting focused on C++23 was intended to take place in Varna in early June 2020, but was cancelled due to the COVID-19 pandemic, as was the November 2020 meeting in New York and the February 2021 meeting in Kona, Hawaii. All meetings until November 2022 were virtual while the November 2022 meeting until the final meeting in February 2023 was hybrid. The standard was technically finalized by WG21 at the hybrid meeting in Issaquah in February 2023. Modern "Hello, world" Example After many library changes applied to the working draft, the new "Hello, world" program will be import std; ...

Caudron C
The Société des Avions Caudron was a French aircraft company founded in 1909 as the Association Aéroplanes Caudron Frères by brothers Gaston and René Caudron. It was one of the earliest aircraft manufacturers in France and produced planes for the military in both World War I and World War II. From 1933 onwards, it was a subsidiary of Renault. Alphonse (Gaston) (1882–1915) and René Caudron (1884–1959) Born in Favières, Somme to parents who farmed nearby in Romiotte, the Caudron brothers were educated at a college in Abbeville. Gaston, as Alphonse was always known, intended to become an engineer but his education was cut short by health problems; René was interested in the development of mechanics and was a sportsman. After military service in an artillery regiment, they returned to work on the farm. They began to build their first aircraft, a large biplane, in August 1908. Initially unable to obtain an engine, they flew it as a glider, towed by a horse, and tested it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Short C-23 Sherpa
The Short C-23 Sherpa is a small military transport aircraft built by Short Brothers. It was designed to operate from unpaved runways and make STOL, short takeoff and landings (STOL). It features a large squared fuselage with a full-width rear cargo door/ramp. The ''C-23A'' and ''C-23B'' are variants of the Short 330 and the ''C-23B+'' is a variant of the Short 360. 60 aircraft were used, it was finally retired from US Army in 2014, but remains in international service. Although it went on to be used for other uses, it was originally the winner of an early 1980s competition for a light cargo aircraft to deliver cargo, especially aviation parts in Western Europe (EDSA). While the C-23 was a new production, as was the C-23B, the C-23B+ were actually Shorts 360, with the tail and rear fuselage of a C-23. One of the differences between the C-23 and C-23B, is that the latter had cabin windows. The aircraft has a substantial amount of civilian use and was also operated by the U.S. Fo ...

Sauber C23
The Sauber C23 was a Formula One racing car designed by Sauber for the 2004 Formula One season. The C23 was driven by Giancarlo Fisichella, who left his previous team Jordan to join Sauber. Felipe Massa, who was a regular driver for Sauber in 2002, returned to Sauber after spending a year as a test driver for Ferrari. Neel Jani was the team's test driver. Overview The car was a direct evolution of the Sauber C22. For this purpose, Ferrari's car from the previous year, the Ferrari F2003-GA, was used as a model. In terms of design, care was taken to make the car lighter and more test than last year's car. For the first time, the Sauber car was equipped with the same Ferrari engine type as Ferrari itself and not, as before, with the respective previous year's engine. The engine was designated the Petronas 04A. The fuel also came from Petronas and the car raced with Bridgestone tyres. The Sauber C23 was unveiled on January 12 in Salzburg at Hangar-7, Red Bull's owned aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C23 Tragedy
The ''C23'' tragedy refers to an incident where the ''Swift''-class patrol boat ''C23'' of the Maritime Squadron of the Armed Forces of Malta (AFM) was severely damaged in an explosion while dumping illegal fireworks off Qala in Gozo, Malta, on 7 September 1984. Seven people – five soldiers and two policemen – were killed, and the only survivor of the incident was severely injured. The patrol boat ''C23'' was repaired and it returned to service, later being renamed ''P23''. It was decommissioned in 2010 and it now remains at the AFM base at Hay Wharf as a memorial to those killed in the explosion. Background The patrol boat ''C23'' was originally built as ''PCF 813'', a Mark II Patrol Craft Fast for the United States Navy. It was one of two Swift boats which were donated to Malta, the other being ''PCF 816''. Both boats arrived in Malta's Grand Harbour on 6 February 1971 on board the USS ''Wood County'', and were designated as ''C-6823'' and ''C-6824'' respectively. The ...

C23 (C Standard Revision)
C23, formally ISO/IEC 9899:2024, is the current open standard for the C programming language, which supersedes C17 (standard ISO/IEC 9899:2018). It was started in 2016 informally as C2x, and was published on October 31, 2024. The freely available draft most similar to the one published is document N3220 (see Available texts, below). The first WG14 meeting for the C2x draft was held in October 2019, virtual remote meetings were held in 2020 due to the COVID-19 pandemic, then various teleconference meetings continued to occur through 2024. In C23, the value of __STDC_VERSION__ changes from 201710L to 202311L. The common names "C17" and "C23" reflect these values, which are frozen prior to final adoption, rather than the years in the ISO standards identifiers (9899:2018 and 9899:2024). Features Changes integrated into the latest working draft of C23 are listed below. Standard Library New functions * Add memset_explicit() function in to erase sensitive data, where memory stor ...

Bishop's Opening
The Bishop's Opening is a chess opening that begins with the moves: :1. e4 e5 :2. Bc4 White attacks Black's f7-square and prevents Black from advancing the d-pawn to d5. By ignoring the beginner's maxim "develop knights before bishops", White leaves their f-pawn unblocked, preserving the possibility of f2–f4. The f2–f4 gives the Bishop's Opening an affinity with the King's Gambit and the Vienna Game, two openings that share this characteristic. The Bishop's Opening can transpose into either of these openings, and in particular a favorable variation of the King's Gambit, but with care Black can circumvent this. Transpositions into the Giuoco Piano and the Two Knights Defense and other openings are also possible. The ''Encyclopaedia of Chess Openings'' assigns the Bishop's Opening the codes C23 and C24. History and use The Bishop's Opening is one of the oldest openings to be analyzed; it was studied by Lucena and Ruy Lopez. Later it was played by Philidor, whose ...

Caldwell 23
NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster. It has an H II nucleus. The object is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in larger apertures. In 1999, the Hubble Space Telescope imaged NGC 891 in infrared. In 2005, due to its attractiveness and scientific interest, NGC 891 was selected to be the first light image of the Large Binocular Telescope. In 2012, it was again used as a first light image of the Lowell Discovery Telescope with the Large Monolithic Imager. Supernova SN 1986J was discovered on August 21, 1986 at apparent magnitude 14.
