The Semitic letter Dāleth may have developed from the logogram for a fish or a door. There are many different Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek and Latin, the letter represented /d/ ; in the Etruscan alphabet the letter was superfluous but still retained (see letter B ). The equivalent Greek letter is Delta, Δ .
D is an object-oriented , imperative , multi-paradigm system programming language created by Walter Bright of Digital Mars and released in 2001. Bright was joined in the design and development effort in 2007 by Andrei Alexandrescu . Though it originated as a re-engineering of C++ , D is a distinct language, having redesigned some core C++ features while also taking inspiration from other languages, notably Java , Python , Ruby , C# , and Eiffel .
