Information:  - The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed and developed at 40,000 rpm. It was admitted for aviation service on May 29, 1961 after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees.  - The Agusta A.115 ( registration I - AGUC ) was a prototype helicopter flown in 1961 in Italy . It was essentially a Bell 47J - 3 with an unclad , tubular tail boom , and powered by a Turbomeca Astazou II turboshaft engine . No production ensued .  - A turboprop engine is a turbine engine that drives an aircraft propeller. In contrast to a turbojet, the engine's exhaust gases do not contain enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller.  - A turboshaft engine is a form of gas turbine which is optimized to produce shaft power rather than jet thrust.  - The Pyrenees (, , , , or ) is a range of mountains in southwest Europe that forms a natural border between France and Spain. Reaching a height of altitude at the peak of Aneto, the range separates the Iberian Peninsula from the rest of continental Europe, and extends for about from the Bay of Biscay (Cap Higuer) to the Mediterranean Sea (Cap de Creus).

Information:  - C++ (pronounced "cee plus plus") is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation.  - Dennis MacAlistair Ritchie (September 9, 1941  October 12, 2011) was an American computer scientist. He created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system. Ritchie and Thompson received the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Bill Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. He was the "R" in K&R C, and commonly known by his username dmr.  - IMAGE (from Imager for Magnetopause-to-Aurora Global Exploration), or Explorer 78, was a NASA MIDEX mission that studied the global response of the Earth's magnetosphere to changes in the solar wind. It was launched March 25, 2000 by a Delta II rocket from Vandenberg AFB and ceased operations in December 2005.  - Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.  - Kenneth Lane "Ken" Thompson (born February 4, 1943), commonly referred to as ken in hacker circles, is an American pioneer of computer science. Having worked at Bell Labs for most of his career, Thompson designed and implemented the original Unix operating system. He also invented the B programming language, the direct predecessor to the C programming language, and was one of the creators and early developers of the Plan 9 operating systems. Since 2006, Thompson has worked at Google, where he co-invented the Go programming language.  - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial.  - Generic programming is a style of computer programming in which algorithms are written in terms of types "to-be-specified-later" that are then "instantiated" when needed for specific types provided as parameters. This approach, pioneered by ML in 1973, permits writing common functions or types that differ only in the set of types on which they operate when used, thus reducing duplication. Such software entities are known as "generics" in Ada, Delphi, Eiffel, Java, C#, F#, Objective-C, Swift, and Visual Basic .NET; "parametric polymorphism" in ML, Scala, Haskell (the Haskell community also uses the term "generic" for a related but somewhat different concept) and Julia; "templates" in C++ and D; and "parameterized types" in the influential 1994 book "Design Patterns". The authors of "Design Patterns" note that this technique, especially when combined with delegation, is very powerful but also quote the following   - Kenneth Cutts Richard Cabot Arnold is an American computer programmer well known as one of the developers of the 1980s dungeon - crawling video game Rogue , for his contributions to the original Berkeley ( BSD ) distribution of Unix , for his books and articles about C and C++ ( e.g. his 1980s -- 1990s Unix Review column , `` The C Advisor '' ) , and his high - profile work on the Java platform . He has two sons , Jareth and Cory .    What object entity has the relation of 'date of birth' with the subject 'ken arnold'?
