Joined the design and development effort in 2007. Though it originated as a re-engineering of, D is a distinct language. It has redesigned some core C features, while also sharing characteristics of other languages, notably, and.The design goals of the language attempt to combine the performance and safety of with the of modern. D code is commonly as fast as equivalent C code, while also being shorter. The language as a whole is not, but does include optional attributes designed to check memory safety., and for allow faster, while, features and a -aware help reduce the occurrence of.
Contents.Features D is designed with lessons learned from practical C usage, rather than from a purely theoretical perspective. Although it uses many and C concepts it also discards some, and is as such not compatible with C and C source code. D has, however, been constrained in its design by the rule that any code that is legal in both C and D should behave in the same way.
D gained some features before C did, for example,. D adds to the functionality of C by also implementing, true, and a re-engineered syntax. D retains C's ability to perform and to add. C is replaced by Java-style with. On the other hand, D's declaration, statement and expression closely matches that of C.The typifies the differences between D and application languages like. An inline assembler lets programmers enter machine-specific within standard D code, a method often used by system programmers to access the low-level features of the needed to run programs that interface directly with the underlying, such as and.D has built-in support for documentation comments, allowing automatic.Programming paradigms D supports five main:, and.Imperative Imperative programming in D is almost identical to that in C. Functions, data, statements, declarations and expressions work just as they do in C, and the C runtime library may be accessed directly.
On the other hand, some notable differences between D and C in the area of imperative programming include D's loop construct, which allows looping over a collection, and, which are functions that are declared inside of another and may access the enclosing function's.Object-oriented Object-oriented programming in D is based on a single inheritance hierarchy, with all classes derived from class Object. D does not support multiple inheritance; instead, it uses Java-style, which are comparable to C's pure abstract classes, and, which separates common functionality from the inheritance hierarchy. D also allows the defining of static and final (non-virtual) methods in interfaces.Metaprogramming Metaprogramming is supported by a combination of templates, compile time function execution, and string mixins.
The following examples demonstrate some of D's compile-time features.Templates in D can be written in a more imperative style compared to the C functional style for templates. This is a regular function that calculates the of a number.

Contents.History Egyptian hieroglyphdoor, fishPhoenicianGreekEtruscanDRomanDThe Semitic letter may have developed from the for a fish or a door. There are many different that might have inspired this. In Semitic, Ancient Greek and Latin, the letter represented /d/; in the the letter was superfluous but still retained (see letter ). The equivalent is Delta,.The (lower-case) form of 'd' consists of a loop and a tall stroke. It developed by gradual variations on the majuscule (capital) form.
In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a at the top of the arc. This serif was extended while the rest of the letter was reduced, resulting in an angled stroke and loop. The angled stroke slowly developed into a vertical stroke.Use in writing systems.
